General Description
The ACE1001 is a member of the ACEx (Arithmetic Controller Engine) family of microcontrollers. It 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 ACE1001 product family has an 8-bit core processor, 64 bytes of RAM, 64 bytes of data EEPROM and 1K bytes of code EEPROM. Its on-chip peripherals include a programmable 8-bit timer with PWM output, watch-dog/idle timer, and programmable undervoltage detection circuitry. The on-chip clock and reset functions reduce the number of required external components. The ACE1001 product family is available in 8-pin SOIC and TSSOP packages.
