INTRODUCTION

The UT80CRH196KDS is compatible with industry standard’s

MCS-96 instruction set. The UT80CRH196KDS is supported

by commercial hardware and software development tools. Built

on UTMC’s Commercial RadHardTM epitaxial CMOS

technology, the microcontroller is hardened against ionizing

dose and charged particles. The microcontroller’s on-board

1000 byte scratch-pad SRAM and flip-flops can withstand

charged particles with energies up to 25 MeV-cm2/mg.

The UT80CRH196KDS accesses instruction code and data via

a 16-bit address and data bus. The 16-bit bus allows the

microcontroller to access 128K bytes of instruction/data

memory. Integrated software and hardware timers, high speed

I/O, pulse width modulation circuitry, and UART make the

UT80CRH196KDS ideal for control type applications. The

CPU’s ALU supports byte and word adds and subtracts, 8 and

16 bit multiplies, 32/16 and 16/8 bit divides, as well as

increment, decrement, negate, compare, and logical operations.

The UT80CRH196KDS’s interrupt controller prioritizes and

vectors 18 interrupt events. Interrupts include normal interrupts

and special interrupts. To reduce power consumption, the

microcontroller supports software invoked idle and power down

modes. The UT80CRH196KDS is packaged in a 68-lead quad

flatpack.
