s DESCRIPTION
MB89820 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 200-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 MB89820 series is therefore best suited to control of LCD display panels.
*: F2MC stands for FUJITSU Flexible Microcontroller.
s FEATURES
• Minimum execution time: 0.
8 µs/5 MHz (VCC = +5.
0 V) • F2MC-8L family CPU core Multiplication and division instructions 16-bit arithmetic operations Instruction set optimized for controllers Test and branch instructions Bit manipulation instructions, etc.
• LCD controller/driver Max.

(Continued) • 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 timer
• 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.
