MB89475PFV-G-129E1

■ DESCRIPTION

The MB89470 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, external interrupt 1 (edge), external interrupt 2 (level) , 10-bit A/D converter, UART/SIO, buzzer, watchdog timer reset.
The MB89470 series is designed suitable for home appliance as well as in a wide range of applications for consumer product.
