1 / 33 page ©2002 Fairchild Semiconductor Corporation 1 www.fairchildsemi.com October 2002 ACE1502 Product Family Rev. 1.7 ACE1502 Product Family Arithmetic Controller Engine (ACEx™) for Low Power Applications 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.
