The MB89490 series is a general-purpose version of the F2MC-8L family, which consists of proprietary 8-bit single-chip microcontrollers. In addition to a compact instruction set, the general-purpose single-chip microcontroller contains various peripheral functions such as a 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, I2C, and watchdog timer reset. The MB89490 series is suitable for compact disc/radio receiver controllers as well as a wide range of applications for consumer products.
The Fujitsu MB89490 series consists of proprietary 8-bit single-chip microcontrollers designed as a general-purpose version of the F2MC-8L family. These devices integrate various peripheral functions including timers, A/D converters, UART/SIO, I²C interfaces, and LCD controllers/driver circuits.
The minimum instruction execution time is 0.32 us when operating at 12.5 MHz.
The LCD controller supports a maximum of 32 segments output and 4 commons.
There are 8 independent channels available for selectable edge detection.
