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.

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)
