OUTLINE
The MB89950 series of single-chip compact microcontroller using the F
2
MC*-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.

(Continued)
• 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)
