General; Features - Fujitsu F2MC-8L Family series Hardware Manual

The MB89950 series of single-chip compact microcontroller using the F
at high-speeds and low voltages. They contain peripheral such as timers, UART, serial interfaces, and
external interrupts, including a 168-pixel LCD controller/driver; they are best suited for use in LCD panels.

1.1 Features

• High-speed processing even at low voltages
Minimum instruction execution time: 0.8 µs/5 MHz (V
• F
2
MC-8L family CPU core
Instruction system most suited to controller
- Multiplication and division instructions
- 16-bit arithmetic operation
- Instruction test and branch instruction
- Bit manipulation instruction, etc.
• LCD controller/driver
- Maximum 42 segment outputs × 4 common outputs
- Built-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 count timer: (usable as both reload timer)
- 20-bit time-based counter
• Two serial interfaces
- 8-bit synchronous serial interface (The transfer direction can be selected to communicate with various
equipment.)
- 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)
• Low-power consumption modes
- Stop mode (Oscillation stops to minimize the current consumption.)
- Sleep mode (The CPU stops to reduce current consumption to about 30% of normal.)
