ACE1502 Product Family

Arithmetic Controller Engine (ACEx™)

for Low Power Applications

ꢀ Hardware Bit–Coder (HBC)

General Description

ꢀ On-chip oscillator

The ACE1502 (Arithmetic Controller Engine) family of microcon-

trollers 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.

— No external components

— 1µs instruction cycle time +/-2% accuracy

ꢀ Instruction set geared for block encryption

ꢀ On-chip Power-on Reset

The ACE1502 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 multifunction

16-bit timer, a watchdog/idle timer, and programmable under-

voltage detection circuitry. On-chip clock and reset functions

reduce the number of required external components. The

ACE1502 product family is available in 8- and 14-pin SOIC,

TSSOP and DIP packages.

ꢀ Programmable read and write disable functions

ꢀ Memory mapped I/O

ꢀ 32-level Low Voltage Detection

ꢀ Brown-out Reset

ꢀ Software selectable I/O option

— Push-pull outputs with tri-state option

— Weak pull-up or high impedance inputs

ꢀ Fully static CMOS
