ACE1202 Arithmetic Controller Engine (ACEx™) for Low Power Applications

January 2000

General Description

The ACE1202 (Arithmetic Controller Engine) is a dedicated pro­grammable monolithic integrated circuit for applications requiring
high performance, low power, and small size. It is a fully static part
fabricated using CMOS technology.

The ACE1202 has an 8-bit microcontroller core, 64 bytes of RAM,
64 bytes of data EEPROM and 2K bytes of code EEPROM. Its on­chip peripherals include a multi-function 16-bit timer, watchdog/
idle timer, and programmable undervoltage detection circuitry.
On-chip clock and reset functions reduce the number of required
external components. The ACE1202 is available in 8- and 14-pin
SO and DIP packages.
