MB89950 Series
LCD (4x42)
DESCRIPTION
The MB89950 series of single-chip compact microcontroller using the F²MC-8L(F²MC stands for FUJITSU Flexible Microcontroller)
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: 0.8µs 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 * 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)
