The 8XC196MH is a member of Intel’s family of 16-bit MCS 96 microcontrollers. It is designed primarily to 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 pulsewidth 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. Operational characteristics are guaranteed over the temperature range of – 40°C to + 85°C.
