General Description

The ACE1101 (Arithmetic Controller Engine) 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 ACE1101 has an 8-bit microcontroller core, 64 bytes of RAM, 64 bytes of data EEPROM and 1K bytes of code EEPROM. Its on chip peripherals include a multi-function 16-bit timer, watchdog/idle timer, and programmable undervoltage detection circuitry. On-chip clock and reset functions reduce the number of required external components. The ACE1101 is available in an 8-pin TSSOP package.
