ACE1202M

运算器引擎（ ACEx⑩ ）针对低功耗应用 Arithmetic Controller Engine ACEx⑩ for Low Power Applications

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.
