ACE1001 Product Family Arithmetic Controller Engine (ACEx™) for Low Power Applications
ACE1001 Product Family
Arithmetic Controller Engine (ACEx™)
for Low Power Applications
General Description
The ACE1001 is a member of the ACEx (Arithmetic Controller
Engine) family of microcontrollers. It is a dedicated programmable
monolithic integrated circuit for applications requiring high perfor-
mance, low power, and small size. It is a fully static part fabricated
using CMOS technology.
The ACE1001 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 programmable
undervoltage detection circuitry. The on-chip clock and reset
functions reduce the number of required external components.
The ACE1001 product family is available in 8-pin SOIC and
TSSOP packages.
