DESCRIPTION
The MB89490 series has been developed as a general-purpose version of the F
2
MC*-8L family consisting of
proprietary 8-bit single-chip microcontrollers.
In addition to a compact instruction set, the general-purpose, single-chip microcontroller contains a variety of
peripheral functions such as 21-bit timebase timer, watch prescaler, PWM timer, 8/16-bit timer/counter, remote
receiver circuit, LCD controller/driver, external interrupt 0 (edge) , external interrupt 1 (level) , 10-bit A/D converter,
UART/SIO, SIO, I
2
C and watchdog timer reset.
The MB89490 series is designed suitable for compact disc/radio receiver controller as well as in a wide range of
applications for consumer product.
