ACE1101

ACE1101 Product Family Arithmetic Controller Engine (ACEx™) for Low Power Applications PRELIMINARY August 2001 ACE1101 Product Family Arithmetic Controller Engine (ACEx™) for Low Power Applications General Description The ACE1101 (Arithmetic Controller Engine) family of microcontrollers 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 product family 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 under-voltage detection circuitry. On-chip clock and reset functions reduce the number of required external components. The ACE1101 product family is available in 8-pin TSSOP, 8-pin DIP and 14-pin DIP packages.
