ACE1001 Product Family
Arithmetic Controller Engine (ACEx™)
for Low Power Applications
I 8-bit Timer1 with PWM output
General Description
I On-chip oscillator
— No external components
— 1µs instruction cycle time
The ACE1001 is a member of the ACEx (Arithmetic Controller
Engine)familyofmicrocontrollers. Itisadedicatedprogrammable
monolithic integrated circuit for applications requiring high perfor-
mance, low power, and small size. It is a fully static part fabricated
using CMOS technology.
I On-chip Power-on Reset
I Brown-out Reset
I Programmable read and write disable functions
I Memory mapped I/O
TheACE1001productfamilyhasan8-bitcoreprocessor,64bytes
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.
