ACE1502 Datasheet, PDF (1/33 Pages) Fairchild Semiconductor – Arithmetic Controller Engine for Low Power Applications
ACE1502 Product Family
Arithmetic Controller Engine (ACEx™)
for Low Power Applications
October 2002
General Description
The ACE1502 (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 ACE1502 product family has an 8-bit microcontroller core,
64 bytes of RAM, 64 bytes of data EEPROM and 2K 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
ACE1502 product family is available in 8- and 14-pin SOIC,
TSSOP and DIP packages.
