ACE1202 Product Family
Arithmetic Controller Engine (ACEx™)
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 de-
tection 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.
