■ DESCRIPTION

The MB89601R series is compact one-chip microcontrollers using the F2MC-8L* CPU core for which can operate at low voltage but at high speed. The microcontrollers contain peripheral functions such as timers, a serial interface and an external interrupt and are applicable to welfare products, especially portable devices required savings in board space.

■ FEATURES

• High-speed processing at low voltage

Minimum execution time: 0.5 µs/3.5 V at 8 MHz

• F2MC-8L family CPU core

• Timer

8-bit PWM timer (also usable as a reload timer)

• Serial interface

Switchable transfer direction allows communication with various equipment.

• External interrupt

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.)
