ACE1501 Product Family Arithmetic Controller Engine (ACEx鈩? for Low Power Applications

December 2003

ACE1501 Product Family

Arithmetic Controller Engine (ACEx鈩?

for Low Power Applications

General Description

The ACE1501 (Arithmetic Controller Engine) family of microcon-

trollers 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 ACE1501 product family 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 multifunction

16-bit timer, a watchdog/idle timer, and programmable under-

voltage detection circuitry. On-chip clock and reset functions

reduce the number of required external components. The

ACE1501 product family is available in 8- and 14-pin SOIC,

TSSOP and DIP packages.
