Atmel Announces 802.11b MAC with Integrated Baseband for Wireless Applications

Atmel Corporation released  three new parts to its family of Wireless LAN products. This family, called Fast-VirtualNet(TM), are single chip baseband Media Access Controllers (MAC) supporting three popular system interfaces: PCMCIA or Compact Flash (AT76C504), USB (AT76C505) and PCI or mini-PCI (AT76C506).

The AT76C504/505/506 chips incorporate an ARM7TDMI® processor to control the on-chip peripherals, manage the internal memory and allocate data queue buffers as well as communicate through the PCMCIA, USB or PCI buses.


Cygnal Flash Microcontroller with  CAN Bus, 12-bit DAC & A/D,  High Voltage Amplifier and Temp Sensor

The C8051F040 has an integrated CAN 2.0B controller with 32 message objects, each with its own filter mask. Integrated analog peripherals include two 12-bit DAC’s, a 12-bit 100KSPS ADC, a +/- 60V common-mode input range programmable gain differential amplifier, comparators, reference, and a temperature sensor.

Based on a 8051 CPU the chip delivers up to 25MIPS at 25MHz. Two UART’s, SPI® bus, and SMBus® serial interfaces are included. On-chip memory resources consist of 64K bytes in-system programmable FLASH and 4352 bytes RAM. The device features on-chip JTAG debug circuitry.

Packaged in either a 100-pin or 64-pin TQFP, C8051F040 family devices start at $16.05 in 1,000 piece quantities.

Hitachi Low Power SH-3 Controllers with USB, IrDA and Super Small Package

The 32-bit SH-3 CPU has a performance of 173 MIPS at 133 MHz operation with power consumption of 1mW/Mhz. The peripheral set on the SH7705 includes 32kByte cache memory, a USB 1.1 transceiver, high-speed serial interfaces with a 64-byte FIFO (First In First Out), a Memory Management Unit,  external memory access controller, and an IrDA Version 1.0 interface for infrared communication.

The new processor is available in two packages, a 28 mm x 28 mm, 208-pin LQFP and a 12 mm x 12 mm, 208-pin Chip Scale Package (CSP).


Microchip Licenses RF Transceiver Technology from Adcon Telemetry

Microchip has licensed a direct sequence spread spectrum (DSSS) transceiver utilizing Adcon's IEEE 802.15.4/ZigBee-compliant transceiver technology.

The agreement enables Microchip to develop products specifically for the low-power wireless, consumer, appliance and home-automation markets.

The ZigBee standard defines "lowest-cost and lowest-power consumption" communications for household appliances and building automation, and is a cost-effective alternative to Bluetooth for all applications involving small volumes of data transmitted over longer distances.


Microchip offers Wireless Sensor Solution

Microchip has partnered with Future Electronics to offer a “Wireless Sensor Solution” reference design kit that provides an easy-to-adopt RF solution.

The reference design kit is a self-contained “working prototype” that highlights Microchip’s rfPIC™ UHF transmitter and the PIC16C925 microcontroller with an LCD driver. The kit includes all of the necessary design files, schematics, PCB layout files, software, and supporting circuitry needed to easily and efficiently design a wireless sensor application.

The core of the transmitter board is Microchip’s rfPIC12C509AF microcontroller which features an RF transmitter with ASK or FSK modulation, PLL and VCO capable of transmissions in the 310-440MHz range, making it ideal for remote control and intermittent RF links. The engine on the receiver board is a PIC16C925 microcontroller with a built-in 32-segment LCD driver to display the sensor reading.

The kit is available from Future Electronics.


Motorola Coldfire CAN/Ethernet Reference Design

The RDM5272C3CAN reference design, based on the ColdFire MCF5272 Version 2 integrated microprocessor, is designed to enable system designers to quickly employ the Ethernet local area network technology alongside CAN technology for distributed control applications. The kit includes schematics, application note, initialization and driver software. The board features: 4MB SDRAM, 2MB FLASH, 10/100 Ethernet, 2 serial ports, USB port.


Texas Instruments Upper-Level Bluetooth Stacks for TMS320C54x DSPs

TROY Wireless, a division of TROY Group, Inc. and Stonestreet One announced that they both have available standard Bluetooth upper-level software for TI's TMS320C54x DSPs.

The new Bluetooth upper-level stacks provide a standard interface that links application-specific Bluetooth profiles with the C54x DSP host processor. Running the stack directly on the DSP eliminates the need for a separate microprocessor and memory for the Bluetooth protocol processing, thereby reducing the cost, size, and power consumption of a DSP- based device.
