ACE8001 Product Family Arithmetic Controller Engine (ACEx™) for Low Power Applications

November 2002

ACE8001 Product Family

Arithmetic Controller Engine (ACEx™)

for Low Power Applications

General Description

The ACE8001 is a member of the ACEx (Arithmetic Controller

Engine) family of microcontrollers. It is a dedicated programma-

ble monolithic integrated circuit for applications requiring high

performance, low power, and small size. It is a fully static part

fabricated using CMOS technology.

The ACE8001 product family has an 8-bit core processor, 64

bytes of RAM, 64 bytes of data EEPROM and 1K bytes of code

EEPROM. Its on-chip peripherals include a programmable 8-bit

timer with PWM output, watch-dog/idle timer, and programma-

ble undervoltage detection circuitry. The on-chip clock and reset

functions reduce the number of required external components.

The ACE8001 product family is available in 8-pin SOIC and

TSSOP packages.
