q 20MHz 16-bit Microcontroller compatible with Industry Standard’s MCS-96 ISA - Register to Register Architecture - 1000 Byte Register RAM q Three 8-bit I/O Ports q On-board Interrupt Controller q Three Pulse-Width Modulated Outputs q High Speed I/O q UART Serial Port q Dedicated Baud Rate Generator q Software and Hardware Timers - 16-Bit Watchdog Timer, Four 16-Bit Software Timers - Three 16-Bit Counter/Timers q Error detection and correction for external memory accesses q QML Q compliant part q Standard Microcircuit Drawing 5962-98583 INTRODUCTION 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.
