OUTLINE

The MB89950 series of single-chip compact microcontroller using the F2MC*-8L family core which can operate at high-speeds and low voltages. They contain peripherals such as timers, UART, serial interfaces, external interrupts and a 168-pixel LCD controller/driver. It is best suited for use in LCD panels.

FEATURES

? Minimum instruction execution time: 0.8 μs at 5 MHz

? F2MC-8L family CPU core

Instruction system most suited to controllers Multiplication and division instructions 16-bit arithmetic operation Instruction test and branch instruction Bit manipulation instruction, etc.

? LCD controller/driver

Maximum 42 segment outputs x 4 common outputs

Build-in LCD driver split resistor

? Three-channel timer unit

8-bit PWM timer: (usable as both reload timer and PWM timer)

8-bit pulse width counter timer: (usable as both reload timer)

20-bit timebased counter

? Two serial interfaces

8-bit synchronous serial interface

UART (5, 7, and 8-bit transfers possible)

? External-interrupt input: 2 channels

2 channels can be used to clear the low-power consumption modes

An edge detection function is provided for each channel

? Low-power consumption modes

Stop mode (Oscillation stops to minimize the current consumption)

Sleep mode (CPU stops to reduce current consumption to about 30)

? Package: QFP-64 (0.65mm pitch)
