need advice on low cost mcu

[artem]

I need to choose 4-8 bit mcu with flash and eeprom (similar to Atmel's tiny
series ) more than 3 - 4 GPIO . The most important criteria is cost - needs to be less than 1 usd .


Thanks in advance

The Pic 12f629 or 675 are 8-pin devices,and if you use the internal 4m clk,you have 6 i/o pins.
Should be about a buck.

Dear Artem,

TI's MSP430F1101A microcontroller has 1K flash and 128 byte RAM.
It's small, low power, has 14 GPIO and cost about 0.99$ for 1000pcs.
And - It's 16 bit.

Atmel also makes the 4-bit MARC4 MCUs.
MARC4 are made both in flash and ROM versions.
I think they are cheaper than Atmel's 8-bit Tiny AVR family.
It's the only 4-bit MCU I have seen with flash program memory.
The flash devices are In-System programmable.

You can use Motorola (Freescale now) MC68HC908QT1. 8 pin, 5 I/O + input only. Metrowerks C compiler free up to 4k. $0.70 @1k.

Microchip will soon launch 6 pin PIC10F20X in SOT23 case!!!

dear friend, could you please tell me where I can find the materals on this? Thanks.

Microchip has just introduced the worlds smallest and first 6-pin MCU, with 4 I/O pins:

Introducing the PIC10F Family – The World’s Smallest Microcontroller
**broken link removed**
Microchip continues to push the limits of the 8-bit microcontroller with its latest innovation, the PIC10F family of 6-pin microcontrollers. This family of microcontrollers packs the high performance of the PIC® microcontroller architecture into the ultra-small form factor of a SOT-23 package for highly space-constrained and extremely low-cost applications.

Atmel's 8-pin AVR's ATtiny11, ATtiny12, ATtiny13 and ATtiny15L are similar 8-pin MCU's with 6 I/O's:

The new ATtiny13 has configurable 128 kHz / 4.8 MHz / 9.6 MHz internal oscillator and can run up to 20 MHz with external oscilator.
AVR doesn't divide the clock by 4 like PIC does.
A PIC with a 4 MHz clock runs at the same speed as an AVR with 1 MHz clock.
