INTRODUCTION

The UT80C196KDS is compatible with industry standard’s

MCS-96 instruction set. The UT80C196KDS is supported by

commercial hardware and software development tools.

The UT80C196KDS 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

UT80C196KD 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

UT80C196KDS’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 UT80C196KDS is packaged in a 68-lead quad flatpack.
