This month's issue:
Tower Semiconductor joined the ARM Foundry Program. eSilicon and Micrel Semiconductor licensed ARM cores.
Atmel announced the availability of its new 16-bit, 32K Smart Card Flash micro controller, the AT90SC3232CS, incorporating Atmel's latest high security architecture. Security features include RSA, DFA/DPA/SPA resistant, DES/TDES co-processor, true RNG (Random Number Generator), firewalls, and environmental protections.
The AT90SC3232CS incorporates 32K bytes of Flash program memory, 32K bytes of EEPROM and 3K bytes of RAM and a SPI interface. Hardware triple DES (Data Encryption Standard) and Elliptic Curve Cryptography (ECC) support, complete the cryptographic features of this device.
Atmel claims this to be "the industry lowest power 8-bit FLASH microcontroller". Further down you'll find three contestants that also lay claim to the industry's lowest power consumption in their respective categories. If low power is what you want, you might also want to check out Texas Instruments low-power MSP430 family, which uses a 16-bit core, or the offerings of Micronas (ROM based).
The new micro controller family is called Mega 169 and consumes 300uA at 1us instruction time, equaling 2MIPS/mW of throughput. A software programmable oscillator can be slowed down to 32KHz reducing current consumption to 20uA in this mode. In HALT mode current consumption drops to 500nA.
The first member of the family features an integrated 24*4 LCD controller. Atmel offers the STK502 expansion module ($99), which together with the STK500 starter kit ($79) allows you to evaluate programs and test the capabilities of the device.
...and another gem from Atmel's marketing department: This device's USB interface is "USB 2.0 compliant" and of course it's "the industry's first". Now, if you thought this means the interface operates at 480Mbps, think again. USB2.0 specifies three speed modes: Low-Speed (1.5Mbps), Full-Speed (12Mbps) and High-Speed (480Mbps). A device is compliant to the spec as soon as it supports one of those speed modes, so any USB device in the world is "USB2.0 compliant", as the spec is backward compatible to the USB1.1 spec. Canon is pulling the same stunt with their USB scanners. So watch out for those "USB2.0 compliant" devices - if 480MBs is what you want or need make sure it says that USB2.0 High-Speed mode is supported.
The AT43USB351M comes
with 24 Kbytes of on-chip mask program ROM and 1 Kbytes of internal SRAM. It
includes a 10 bits A -to-D converter with 12 channels, a PWM with two outputs,

The device features a 24-bit (16MB) external memory interface and hardware math accelerator for 16/32 bit multiply/divide. It comes in a 100 pin LQFP package and costs $8.89 in 1000 unit quantities.
EM Microelectronic has released the EM6625 and EM6626 masked ROM microcontrollers with a built-in 4 MUX LCD driver. The EM6625/26 circuits consume only 1.6uA in active mode and 0.4uA in the standby mode (LCD off) and 0.2uA in sleep mode. They also include a melody generator that can be used for basic sound generation, a 10-bit universal counter with PMW function, SPI interface and a low voltage detector with 8 software selectable trigger levels. The EM6625/26 microcontrollers' supply voltage ranges from 1.2V to 3.6V. ROM size is 4k*16 bits and RAM 128*4 bits. The EM6625 drives 20 segments, three or four times multiplexed, while the EM6626 drives 32 segments, three or four times multiplexed.
With a typical power consumption of 200mW at 173MIPS throughput, the SH7705 achieves 0.865MIPS/mW.
The SH7705 incorporates a SuperH® 32-bit RISC SH-3 CPU core that operates with a large 32-kilobyte (32KB), one-cycle access cache memory. The device's USB interface supports full-speed mode (12Mbs), an integrated USB transceiver eliminates the need for an external transmitter IC. Other peripheral functions provided are: a 2-channel high-speed serial interface with a 64-byte first in first out (FIFO), memory management unit (MMU), bus state controller (BSC), which provides glue less interfaces for various kinds of memory such as synchronous DRAM and a 4-channel direct memory access controller (DMAC). The SH7705 also offers timers, a real-time clock (RTC), 4-channel 10-bit analog-to-digital converter (ADC) and an IrDA (Infrared Data Association) Version. 1.0 interface for infrared communication.
The device comes in a 100MHz or 133MHz version in 208 pin LQFP or CSP packages and pricing ranges from $12.15...$15.00 in 10k unit quantities.
The new MyVP (My
Virtual Processor) technology announced by Infineon is based on a series of
innovations that make it possible
A 10X improvement in
performance can be seen in cost-sensitive embedded systems, where processors
running at speeds of 400 megahertz (MHz) are paired with low-cost external Flash
memory at 40 MHz. In such a scenario a processor can waste 90 percent of its
time waiting for instructions from that slow memory. With MyVP technology, an
embedded processor acts like multiple separate “virtual” processors. When one
processor task is forced to wait, the other “virtual” processor takes over,
making efficient use of 100 percent of the chip’s
The PIC16F630 and
PIC16F676 devices offer a typical standby current of 100nA at 2.0V and a wide
operating voltage range from
Available today in
14-pin TSSOP, PDIP and SOIC packages, pricing in high volume is $0.79 cents each
for the PIC16F630 and $0.91 cents each for the PIC16F676.
With 6 new devices offering 100nA standby current, Microchip claims to provide "industry leading power management" with its nanoWatt technology. Unfortunately they fail to provide any data on the devices current consumption when they are actually doing something (i.e. in active mode) in the press release. We would say that the majority of micros in the market fall into the "nanoWatt" category when the clock is switched off.
The new PIC18FXX20
family offers a flexible clock system with six enhanced "software controlled"
power-managed modes. Additional features include a new low-current watchdog
timer, a 2-speed start-up from a reset or sleep mode and a new fail-safe clock
monitor that is used to detect an external clock failure.
include 18-pin PDIP and SOIC, 20-pin SSOP, 28-pin PDIP, SOIC, Quad Flat No-Lead
(QFN) and 44- and 40-pin PDIP, TQFP, QFN packages. The PIC18FXX20 family is
priced between $1.80 and $3.50 in volume manufacturing quantities depending on
device, temperature range, package and operating voltage.
