Preliminary
MSM66587 Family
OKI Original High Performance CMOS 16-Bit Microcontroller
GENERAL DESCRIPTION
The MSM66587 Family consists of high-performance, 16-bit CMOS single-chip microcontrollers based
on Oki's own architecture. On-chip peripherals include two switchable real-time channels, one 16-bit
PWM channel, five external interrupt input channels, one serial output channel, and an 8-bit analog-to-
digital converter. The chips are ideal for system control applications controlling decoder LSIs, digital
signal processors, and host interface LSIs in equipment such as CD-ROM drives and magneto-optical
drives. Their low-profile packages and built-in pull-up resistors, programmability at bit level, contrib-
ute to the compactness of the final design. The family includes the flash ROM version MSM66Q587,
rewritable with a +5V power supply, the one-time PROM version MSM66P587, and the ROM-less
MSM66X587.
