Analog Devices Pairs 24-bit Sigma-Delta ADCs with ARM7 Core

The ADuC706x family expands ADI's precision analog microcontroller portfolio by incorporating two 24-bit sigma-delta analog-to-digital converters (ADCs) and a host of analog peripherals with a 32-bit ARM7 core to create a solution for precision sensing applications. The combination of small size, low operating power and Analog Devices' data conversion design expertise distinguishes the ADuC706x, eliminating the complexity, cost and performance degradation issues associated with discrete mixed-signal solutions.

Designed for 4–20 mA loop-powered applications in factory automation and for precision instruments, the ADuC706x family includes the ADuC7060, ADuC7061 and ADuC7062.
The devices feature an ADC noise performance of just 60 nV -- 20% better than the nearest competing part -- and offer five times more processing power for a given clock rate. In addition to the 24-bit sigma-delta ADCs and ARM7 core with eight interrupt priority levels, the new precision analog microcontrollers incorporate 32 Kbytes of flash memory and 4 Kbytes of SRAM, a programmable gain amplifier, multiplexers, buffers, an auxiliary 24-bit ADC for cold junction compensation and interfacing to thermocouple applications, and SPI, UART and I2C ports. The devices consume just 2.6 mA with all peripherals activated.

The ADuC7060, available in a 7 mm × 7 mm 48-pin chip-scale (QFN) package, offers more analog-input channels and general-purpose I/Os than other devices in the family. The ADuC7061 and ADuC7062 come in 5 mm × 5 mm 32-pin chip-scale (QFN) packages, ideal for space-constrained applications. The ADuC7062 does not include the auxiliary ADC channel.

The ADuC706x family is available in sample quantities and will be in full factory production in November 2008. The ADuC7060, ADuC7061 and ADuC7062 precision analog microcontrollers are priced at $4.90, $3.95 and $3.40 respectively, in 1,000-unit quantities.

Atmel Announces ARM7-based MCU with FPGA Interface to Multi-layer AHB

Atmel announced the AT91CAP7E, the industry's first ARM7-based MCU with a direct FPGA interface. The AT91CAP7E is a standard microcontroller with an FPGA interface that makes the FPGA look and work like it is on the internal bus of the MCU. It provides customers with a two-chip, no-NRE, FPGA-plus ARM7 solution and offers an engineering-free migration path to a lower cost, and a lower-power customizable MCU.

The CAP7E includes a six-layer advanced high-speed bus (AHB), peripheral DMA controller and 160 Kbytes of on-chip SRAM. On-chip peripherals include USB 2.0 full speed device, SPI master and slave, two USARTs, three 16-bit timer counters, an 8-channel/ 10-bit analog to digital converter, plus a full-functioned system controller including interrupt and power control and supervisory functions. The FPGA interface on the CAP7E provides the FPGA with direct access to the CAP7E's on-chip AHB and peripheral DMA controller. This architecture eliminates FPGA-induced bus contention, off-loads MCU-to-FPGA communications from the CPU, and frees up the external bus interface for external memory access.

The FPGA interface on Atmel's CAP7E provides the FPGA with two AHB masters, four AHB slaves, a special direct AHB slave interface to an external RAM through the FPGA, and a programmable ROM that remaps the external RAM to emulate and debug the ROM code. Fourteen advanced peripheral bus (APB) slaves, two full-duplex DMA channels and 32-bit programmable I/O may be hardware selected to share I/O. An on-chip priority interrupt controller provides up to 13 encoded interrupts and two additional un-encoded interrupts for DMA transfers.

The same C compilers, real-time operating systems, in-circuit emulators and integrated development environments used with Atmel's AT91SAM ARM-based MCUs can be used with CAP.

Atmel's AT91CAP7E is available now and is priced at US$9.50 in quantities of 10,000 units in a 225 BGA package.

Atmel Introduces New picoPower tinyAVR MCUs

Atmel announced two new low-power 32-pin tinyAVR microcontrollers -- the ATtiny48 and ATtiny88 devices -- which have 4 and 8 Kbytes of Flash memory, respectively. These AVR microcontrollers consume less than 240 uA at 1.8V and 1 MHz, and below 100 nA in power-down mode.

The new tinyAVR microcontrollers utilize Atmel's picoPower technology that eliminates unnecessary power consumption. They have a zero-power brown-out detection circuitry that can be turned off during sleep modes, a power reduction register that powers down individual peripherals, and digital input disable registers that remove leakage current on ADC input pins.

The ATtiny48/88 operates from 1.8 to 5.5 volts and features a 10-bit ADC, SPI, I2C interface, internal temperature sensor, and have up to 12 MIPS throughput at 12 MHz. Like all the other AVR microcontrollers, the ATtiny48/88 features an on-chip debug system.

All tinyAVR microcontrollers use the standard AVR microcontroller development tools. The AVR Studio AVR integrated development environment is available free of charge on Atmel's web site.

Samples for the ATtiny48 are available now. The ATtiny88 will be available in Q3 2008 in QFN32, QFN28, TQFP32 and PDIP28 packages. Volume prices for 10,000 units are $0.80 for the ATtiny48 and $1.04 for the ATtiny88.

Freescale Unveils MC13224 Single-chip IEEE 802.15.4/ZigBee Platform

Freescale is now sampling the next-generation MC13224 device in its single-chip IEEE 802.15.4/ZigBee Platform-in-Package (PiP) family. This family is based on IEEE 802.15.4 technology, known for its benefits in the areas of cost, performance and efficiency for real-time remote monitoring and control.

This latest addition to the MC1322x family is designed for a range of wireless applications, including energy management, commercial building automation, industrial control and monitoring and home entertainment control. The family supports existing protocols, such as SMAC, IEEE 802.15.4 MAC, ZigBee stack and Synkro network protocol stack, with the ability to support the WirelessHART specification, ISA100 and 6LoWPAN.

The MC13224 device is based on the IEEE 802.15.4 specification and designed to provide a highly integrated, total solution with premier processing capabilities and very low power consumption. Freescale has done this by integrating the essential components of an IEEE 802.15.4 based application within a single package, requiring designers to add only an antenna and crystal.

The MC13224 contains a 32-bit ARM7 microcontroller, a fully compliant IEEE 802.15.4 transceiver, flash, RAM and ROM, high-performance peripherals, balun and RF matching components. This is all integrated into a small-footprint land-grid array (LGA) package that virtually eliminates the need for external RF matching components.

Typical transmit currents of 28 mA and receive currents of 21 mA can even be lower with MCU bus stealing enabled. With receive sensitivity of up to -100 dBm and maximum output power of +5 dBm, the MC1322x offers the highest link margin of any device currently available in the industry. On-board power supply regulation is provided for source voltages from 1.8 Vdc to 3.6 Vdc, and can operate over an extended temperature range up to +105C.

The MC1322x family is engineered to double the expected battery life for current IEEE 802.15.4 and ZigBee protocol solutions, in many cases exceeding the shelf life of batteries. It does this by providing numerous low-current modes to maximize battery life with sleep or restricted-performance operation, and also contains an on-board buck converter that takes advantage of the operating characteristics of Lithium-ion or NiCad batteries.

MC1322x development kits are orderable now. Production quantities are expected to be available in September. Suggested resale pricing for the MC13224V in 10,000 resale quantities is $4.99 (USD).

With more than 50 percent more processing performance and double the Flash and RAM memory of previous 1xx, 2xx or 4xx generations, the F5xx devices help systems perform demanding tasks while operating from very limited power sources. A wake-up time of less than 5 microseconds with full status retention from both standby and sleep modes provides full performance on demand and instant reaction to events like external interrupts. Multi-channel DMA permits data exchange with peripherals while the core remains in low-power modes.

A true 32-bit real-time clock with an alarm requires just 1.5 uA of standby current, enabling batteries to operate without servicing for 20 years or longer. A new, cutting-edge power management module offers flexibility to choose the optimum core voltage dynamically for lowest power vs. performance requirements while enabling accurate power-on-reset and supply voltage supervision with monitoring. A unified clock system offers a selection of clocks to achieve the right mix of power and precision, including an option for operation without a crystal.

Intelligent, high-performance digital and analog peripherals consume no power when not in operation, and future F5xx devices will include peripherals such as RF, USB, encryption and LCD interfaces. A new high-resolution timer will offer advanced processing capabilities to enable applications like voice-activated home security systems. Up to 1 MB of linear memory mapping enables robust user interfaces, as well as applications for ZigBee and other low-power RF sensor networks.
F54xx devices offer up to 16 kilobytes of RAM and up to 256 KB Flash, doubling Flash and RAM available on previous MSP430F2xx, F1xx and F4xx devices. The new devices offer read/erase/write capability down to 1.8 V. For applications based on two AAA batteries, Flash write is possible down to the battery end-of-life voltage of 0.9 V for each battery.

The MSP430F5xx generation is 100 percent instruction set compatible with earlier-generation MSP430 devices. MSP430F5438IPZ devices are sampling now and MSP430F5437IPN, F5436IPZ, F5435IPN, F5419IPZ and F5418IPN will be released in August 2008, with additional F5xx introductions scheduled for the coming months. Package options include both 80- and 100-pin TQFPs -- the latter with additional general-purpose I/Os.

Winbond  Releases W79E8213 8-bit Controllers

Winbond is introducing new versions of the W79E8213 8-bit controllers. W79E8213 feature the Winbond 8051 core, which is capable of executing a single command in 4 clock cycles. It has a built-in 4K flash memory and is highly integrated with peripheral functions (e.g. 10-bit ADC, Buzzer, PWM, and internal restoration). The key features include fast execution, high noise immunity, and stability. They are all suitable for common embedded applications that require high performance in small packages.

The product's design calls for a small package that contains sufficient I/O and memory capacity for the desired application. Unique solutions can be used with this series of products such as power controller, motor controller, air conditioner, and treadmill machines. In-circuit programming functions can be used to directly program and update the system while it is still online.

Zilog Introduces Enhanced Zatara ARM9-Based ASSP

Zilog has added a new product to its Zatara family of ARM9-based ASSPs for secure transactions. Offering the very latest PCI PED certification, the new product offers customers more design flexibility, and meets the needs of those customers who require a more integrated security system. It also showcases a new on-chip Dual-Role USB OTG controller and several new security enhancements that strengthen the overall security system against tampering and other attacks.

The new Zatara ZA9L1 ASSP, as it has been designated, is an ARM9-based, 32-bit RISC SoC solution designed for a variety of security-critical applications, including payment, identity, healthcare, access control, e-government, and e-administration.

All of Zilog's Zatara ASSPs are EMV and PCI PED pre-certified for point-of-sale applications, helping customers streamline the system certification process.

The new Dual-Role USB OTG cuts the time it takes for developers to design trusted devices. It eliminates the need for an external USB controller. The reduced external component count cuts total system costs, reduces power consumption, and streamlines time-to-market.

Since the Zatara ASSP is based on ARM core technology, designers can fully take advantage of a wide variety of tools and third-party support available for ARM-based architectures.
