DESCRIPTION
MB89820 series is a line of single-chip microcontrollers using the F
2
MC-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.
* : F

MC stands for FUJITSU Flexible Microcontroller.

• 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.)

DIFFERENCES AMONG PRODUCTS
1. Memory Size
Before evaluating using the piggyback product, verify its differences from the product that will actually be used.
Take particular care on the following points:
• On the MB89821, the register bank address upper than 0140
H
cannot be used. On the MB89823R, MB89825
and MB89P825, each register bank addresses upper than 0180
H
can be used.
• On the MB89P825, addresses BFF0
H
to BFF6
H
comprise the option setting area, option settings can be read
by reading these addresses.
• The stack area, etc., is set at the upper limit of the RAM.
2. Current Consumption
• In the case of the MB89PV820, add the current consumed by the EPROM which is connected to the top socket.
• However, the current consumption in sleep/stop modes is the same. (For more information, see section
“s Electrical Characteristics.”
3. Mask Options
Functions that can be selected as options and how to designate these options vary by the product.
Before using options check section “s Mask Options.”
Take particular care on the following point : Options are fixed on the MB89PV820.
