■ DESCRIPTION

The MB89490 series has been developed as a general-purpose version of the F2MC*-8L family consisting of proprietary 8-bit single-chip microcontrollers.

■ FEATURES

? Package used

QFP package for MB89F499, MB89497,MB89498

MQFP package for MB89PV490

? High speed operating capability at low voltage

? Minimum execution time: 0.32 μs/12.5MHz

? F2MC-8L family CPU core

Instruction set optimized for controllers

Multiplication and division instructions

PWM timer x 2

8/16-bit timer/counter x 2

21-bit timebase timer

Watch prescaler

? External interrupt

Edge detection (selectable edge) : 8 channels

Low level interrupt (wake-up function) : 8 channels

? 10-bit A/D converter (8 channels)

10-bit successive approximation type

? UART/SIO

Synchronous/asynchronous data transfer capability

? SIO

Synchronous data transfer capability

? LCD controller/driver

Max. 32 segments output x 4 commons

? I2C interface circuit

? Remote receiver circuit

? Low-power consumption mode

Stop mode (oscillation stops so as to minimize the current consumption.)

Sleep mode (CPU stops so as to reduce the current consumption to approx. 1/3 of normal.)

Watch mode (everything except the watch prescaler stops so as to reduce the power comsumption to an extremely low level.)

Sub-clock mode

? Watchdog timer reset

? I/O ports: max. 66channels
