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.

Description
Analog signal input pin for A/D converter
Power supply input pin for A/D converter
Reference voltage input pin for A/D converter
GND input pin for A/D converter
Basic clock oscillation pin
When P0, P1, P2, P7_4-P7_7, and P8-P11 are in an output state and OE pin is "H"
level, P0, P1, P2, P7_4-P7_7, and P8-P11 go to a high-impedance state.
When P0, P1, P2, P7_4-P7_7, and P8-P11 are in an output state and OE pin is "L"
level, P0, P1, P2, P7_4-P7_7, and P8-P11 output "H" or "L" level.
However, when P0, P1, P2, P7_4-P7_7, and P8-P11 are in an input state, these
ports are not under the influence of OE pin.
Nonmaskable interrupt request input pin
Low-active RESET input pin
Normally set to "H" level. If set to "L" level, the program memory goes into
external access mode and accesses external program memory
Power supply pin
Ground pin
