8XC196MH INDUSTRIAL MOTOR CONTROL

CHMOS MICROCONTROLLER

control three-phase AC induction and DC brushless motors. It features an enhanced three-phase waveform

generator specifically designed for use in “inverter” motor-control applications. This peripheral provides pulse-

width modulation and three-phase sine wave generation with minimal CPU intervention. It generates three

complementary non-overlapping PWM pulses with resolutions of 0.125 µs (edge triggered) or 0.250 µs

(centered).

The 8XC196MH has two dedicated serial port peripherals, allowing less software overhead. The watchdog timer

can be programmed with one of four time options.

The 8XC196MH is available as the 80C196MH, which does not have on-chip ROM, the 87C196MH,

which contains 32 Kbytes of on-chip OTPROM* or factory programmed ROM, and the 83C196MH, which

contains 32 Kbytes of factory programmed MASK ROM. It is available in 84-lead PLCC, 80-lead Shrink EIAJ/QFP,

and 64-lead SDIP. The 64-lead package does not contain pins for the P5.1/INST and P6.7/PWM1 signals.

*One-Time Programmable Read-Only Memory (OTPROM) is similar to EPROM but comes in an unwindowed package and

cannot be erased. It is user programmable.
