ACE1202 Product Family Arithmetic Controller Engine (ACEx鈩? for Low Power Applications

PRELIMINARY

August 2001

ACE1202 Product Family

Arithmetic Controller Engine (ACEx鈩?

for Low Power Applications

General Description

The ACE1202 (Arithmetic Controller Engine) family of

microcontrollers is a dedicated programmable monolithic inte-

grated circuit for applications requiring high performance, low

power, and small size. It is a fully static part fabricated using

CMOS technology.

The ACE1202 product family has an 8-bit microcontroller core, 64

bytes of RAM, 64 bytes of data EEPROM and 2K bytes of code

EEPROM. Its on-chip peripherals include a multi-function 16-bit

timer, watchdog/idle timer, and programmable undervoltage de-

tection circuitry. The on-chip clock and reset functions reduce the

number of required external components. The ACE1202 product

family is available in 8- and 14-pin SOIC and DIP packages.
