■ 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
16-bit arithmetic operations
Test and branch instructions
Bit manipulation instructions, etc.
• Clock
Embedded PLL clock multiplication circuit for sub-clock
Operating clock (PLL for sub-clock) can be selected four times of the sub- clock oscillation
• Six timers
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
