■ DESCRIPTION

The MB89660 series has been developed as a general-purpose version of the F2MC*-8L family consisting of proprietary 8-bit single-chip microcontrollers.

In addition to a compact instruction set, the microcontrollers contain a variety of peripheral functions such as timers, a UART, a serial interface, an 8-bit A/D converter, an input capture, an output compare, and an external interrupt. The MB89660 series is applicable to a wide range of applications from welfare products to industrial equipment.

■ FEATURES

• Package expansion

QFP package

SDIP package

• F2MC-8L family CPU core

Instruction set optimized for controllers

Multiplication and division instructions

16-bit arithmetic operations

Test and branch instructions

Bit manipulation instructions, etc.

• Three types of timers

8-bit PWM timer

8/16-bit timer/counter

20-bit time-base timer

• Functions that permit communications with a variety of devices

UART which permits selection of synchronous/asynchronous communications

A serial interface that permits selection of the transfer direction

• 8-bit A/D converter: 8 channels

Sense mode function capable of performing compare operation in 5 µs

Activation by external input possible

• Real-time control

Input capture: 2 channels

Output compare: 2 channels

• External interrupt: 4 channels

Two channels are independent and capable of wake-up from low-power consumption modes (with an edge detection function).

• Low power consumption modes

Stop mode (Oscillation stops to minimize the current consumption.)

Sleep mode (The CPU stops to reduce the current consumption to approx. 1/3 of normal.)

Hardware standby mode (Wake-up from this mode and activation by pin input only.)
