Low power microcontrollers

[firmy]

Hi,
Any suggestion on a low power micro controller (32-bit running an RTOS) that is available in the market. This is to be used for a battery powered mobile application hence power consumption of the micro is very critical.

Maybe some ARM core based , ie from Atmel, Philips.
Hitachi also have good controllers.

Microchip has LF series of micros.

Hi

I can recomend you to use the MSP430 from TI but it's 16 bit only it have a capability to run RTOS {up to 16 mips with the MSP430F2xx} and you can find many free one


All the best

Hi firmy:
We've designed several hand-held products with Samsung 32bit Arm920 based chip S3C2410. there's photos of S3C2410 on our web. It has a good power effciency. Freescale i.MX or i.MX21 is also very good for hand held applications.

Hi,

You're looking for a 32 bit processor, but the most low power microcontroller that I know is the the TI MSP430 devices. In active mode the power current is up to 200uA and in low power mode is 2uA. And you can also use a real time OS with MSP430 deevices. It's very ease to program. The MSP lose only in the instruction cicle, 125ns, and all structions spend around 3 or 4 cilcles.

Is it.

Renesas have good microcontrollers with huge capabilites. The development tools not very expensive! Try at: www.renesas.com

USE MSP430 family...from TI

warning #1 - the same answer as proposed above by emanuelcsm

Try Renesas Super Low Power family.
