ACE8001 Product Family
Arithmetic Controller Engine (ACExTM)
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.
