■ DESCRIPTION

The MB89850R series has been developed as a general-purpose version of the F2MC*-8L family consisting of proprietary 8-bit, single-chip microcontrollers.

■ FEATURES

• Various package options

SDIP package (64 pins)/QFP package (64 pins)

• 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.

• 8-bit PWM timers: 2 channels

Also usable as a reload timer

• UART

Full-duplex double buffer

Synchronous and asynchronous data transfer

• 8-bit serial I/O

Switchable transfer direction allows communication with various equipment.

• 10-bit A/D converter

Conversion time: 13.2 µs

Activation by an external input or a timer unit 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 minimize the current consumption.)

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

• Bus interface functions

Including hold and ready functions

• Timer unit

Outputs non-overlap three-phase waveforms to control an AC inverter motor.

Also usable as a PWM timer (4 channels)
