General Description
The ACE1202 (Arithmetic Controller Engine) family of microcontrollers is a dedicated programmable monolithic inte grated circuit for applications requiring high performance, low power, and small size. It is a fully static part fabricated using CMOS technology.
The ACE1202 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 multi-function 16-bit timer, watchdog/idle timer, and programmable undervoltage detection circuitry. The on-chip clock and reset functions reduce the number of required external components. The ACE1202 product family is available in 8- and 14-pin SOIC and DIP packages.
