F2MC-8L MB89480/MB89480L Series
MB89485/485L/P485/P485L/PV480
s DESCRIPTION
The MB89480 series has been developed as a general-purpose version of the F2MC*-8L family consisting of
proprietary 8-bit single-chip microcontrollers.
In addition to a compact instruction set, the microcontroller contains a variety of peripheral functions such as 21-
bit timebase timer, watch prescaler, PWC timer, PWM timer, 8/16-bit timer/counter, 6-bit PPG, LCD controller/
driver, external interrupt 1 (edge), external interrupt 2 (level), 10-bit A/D converter, UART/SIO, buzzer, watchdog
timer reset.
The MB89480 series is designed suitable for LCD remote controller as well as in a wide range of applications for
consumer product.
*: F2MC stands for FUJITSU Flexible Microcontroller.
