M66242P/FP
4-4-CH 12-BIT PWM GENERATOR
MIMITSUBISHI
DIDIGITAL ASSP
DESCRIPTION
M66242 Integrated Circuit has four 12-bit PWM (pulse width
modulation) circuits which are built by using the CMOS
(complementary metal oxide semiconductor) process.
This IC controls PWM waveform by adjusting the “H” width
according to serial data sent from MCU (micro controller unit)
or other device. Each channel can be independently con-
trolled.
High-resolution digital-analog converter can be formed eas-
ily by connecting a low-pass filter circuit to the output pins of
this circuit.
FEATURES
Built-in four 12-bit high-resolution pulse width modulation
circuits
Easy digital-analog conversion – Quick output waveform
smoothing
Control by 1.22mV possible per step (V
CC
=5V)
Serial data input
“H” level width setting type
4 independently controlled channels
All 4 channels reset by reset input (R) High-impedance sta-
tus after reset
All 4 channels controlled by output control input (OC)
Settings take effect after ongoing cycle is completed
Input: TTL level
Output: CMOS 3-state output
