MSM66589/66P589/66Q589
OLMS-66K Series CMOS 16-Bit Microcontroller
GENERAL DESCRIPTION
The MSM66589/66P589/66Q589 is a high-speed, high-performance 16-bit microcontroller that
employs OKI original nX-8/500S CPU core.
The MSM66589/66P589/66Q589 includes a 16-bit CPU, ROM, RAM, a 10-bit A/D converter,
serial ports, flexible timers, pulse-width modulator (PWM), and I/O ports.
The MSM66Q589 is a Flash EEPROM version.
