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 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.
Operational characteristics are guaranteed over the temperature range of – 40°C to + 85°C.
*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.
Intel Corporation assumes no responsibility for the use of any circuitry other than circuitry embodied in an Intel product. No other circuit patent
licenses are implied. Information contained herein supersedes previously published specifications on these devices from Intel.

PROCESS INFORMATION
This device is manufactured on PX29.5, a CHMOS IV
process. Additional process and reliability information
is available in Intel’s Components Quality and
Reliability Handbook (order number 210997).
All thermal impedance data is approximate for static
air conditions at 1 watt of power dissipation. Values
will change depending on operating conditions and
the application. The Intel Packaging Handbook (order
number 240800) describes Intel’s thermal impedance
test methodology.
