■ 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.)
