ACE1202 Product Family Arithmetic Controller Engine (ACExTM) for Low Power Applications
ACE1202 Product Family
Arithmetic Controller Engine (ACExTM)
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.
