■ DESCRIPTION

The MB89628R/629R/P629 have been developed as a general-purpose version of the F2MC*-8L family consisting of proprietary 8-bit, single-chip microcontrollers.

In addition to the F2MC-8L CPU core which can operate at low voltage but at high speed, the microcontrollers contain a variety of peripheral functions such as timers, serial interfaces, an A/D converter, and an external interrupt.

The MB89628R/629R/P629 are applicable to a wide range of applications from welfare to industrial equipment, including portable devices.

■ FEATURES

• Large-size RAM

MB89P629: 4 Kbytes

MB89628R: 3 Kbytes

MB89629R: 3 Kbytes

• High-speed processing at low voltage

Minimum execution time: 0.4 µs/3.5 V, 0.8 µs/2.7 V

• 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.

• Four types of timers

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

8-bit pulse width count timer (Continuous measurement capable, applicable to remote control, etc.)

16-bit timer/counter

20-bit time-base timer

• Two serial interfaces

Swichable the transfer direction allows communication with various equipment.

• 8-bit A/D converter

Sense mode function enabling comparison at 5 µs

Activation by an external input capable

• External interrupt: 4 channels

Four 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 reduce the current consumption.)

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