■ DESCRIPTION

MB89800 series is a line of single-chip microcontrollers using the F2MC-8L* CPU core which can operate at low voltage but at high speed. In addition to an LCD controller/driver allowing 240-pixel display the microcontrollers contain a variety of peripheral functions such as timers, a UART, a serial interface, and an external interrupt. The configuration of the MB89800 series is therefore best suited to control of LCD display panels.

■ FEATURES

• Minimum execution time: 0.4 µs/10 MHz (Vcc = +5.0 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.

• LCD controller/driver

Max 70 segments/4 commons

Divided resistor for LCD power supply

• Three types of timers

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

8-bit pulse width count timer (also usable as a reload timer)

20-bit time-base counter

• Two serial interfaces

8-bit synchronous serial interface (Switchable transfer direction allows communication with various equipment.)

UART (5-, 7-, 8-bit transfer capable)

• External interrupt: 2 channels

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.)
