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 time-base 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. Note: *: F²MC stands for FUJITSU Flexible Microcontroller.
