ACE1502 Product Family Arithmetic Controller Engine (ACExTM) for Low Power Applications
The ACE1502 (Arithmetic Controller Engine) family of microcontrollers is a dedicated programmable monolithic integrated circuit for applications requiring high performance, low power, and small size. 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 undervoltage 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.
