ACE1202

Arithmetic Controller Engine (ACEx™)

for Low Power Applications

I 16-bit multifunction timer with difference capture

General Description

I On-chip oscillator

— No external components

— 1µs instruction cycle time

The ACE1202 (Arithmetic Controller Engine) is a dedicated pro-

grammable monolithic integrated circuit for applications requiring

high performance, low power, and small size. It is a fully static part

fabricated using CMOS technology.

I Instruction set geared for block encryption

I On-chip power on reset

The ACE1202 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 detection circuitry.

On-chip clock and reset functions reduce the number of required

external components. The ACE1202 is available in 8- and 14-pin

SO and DIP packages.

I Programmable read and write disable functions

I Memory mapped I/O

I Multilevel Low Voltage Detection

I Fully static CMOS

— Low power HALT mode (100nA @3.3V)

— Single supply operation (2.0-5.5V, 2.2-5.5V, 2.7-5.5V)

I Software selectable I/O options

— Push-pull outputs with tri-state option

— Weak pull-up or high impedance inputs
