ACE1101 Arithmetic Controller Engine (ACEx™) for Low Power Applications
ACE1101
Arithmetic Controller Engine (ACEx™)
for Low Power Applications
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 onchip 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.
