INTRODUCTION
The UT80C196KD is compatible with industry standard’s
MCS-96 instruction set. The UT80C196KD is supported by
commercial hardware and software development tools.
The UT80C196KD 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
UT80C196KD’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 UT80C196KD is packaged in a 68-lead quad flatpack.
