ACE1101 Arithmetic Controller Engine (ACEx™) for Low Power Applications

PRELIMINARY

May 1999

ACE1101

Arithmetic Controller Engine (ACEx™)

for Low Power Applications

General Description

The ACE1101 (Arithmetic Controller Engine) is a dedicated pro-

grammable monolithic integrated circuit for applications requiring

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

fabricated using CMOS technology.

The ACE1101 has an 8-bit microcontroller core, 64 bytes of RAM,

64 bytes of data EEPROM and 1K bytes of code EEPROM. Its on-

chip 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 ACE1101 is available in an 8-pin

TSSOP package.
