MB89820 series is a line of single-chip microcontrollers using the F²MC-8L(F²MC stands for FUJITSU Flexible Microcontroller) 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.

|
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.)
