F2MC-8L MB89490 Series
MB89497/498/F499/PV490
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.
In addition to a compact instruction set, the microcontroller contains a variety of peripheral functions such as
21-bit timebase timer, watch prescaler, PWM timer, 8/16-bit timer/counter, remote receiver control, 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 designed suitable for compact disc/cassette tape/radio receiver controller as well as in
a wide range of applications for consumer product.
*: F2MC stands for FUJITSU Flexible Microcontroller.

DIFFERENCES AMONG PRODUCTS
1. Memory Size
Before evaluating using the piggyback product, verify its differences from the product that will actually be used.
Take particular care on the following point:
• The stack area is set at the upper limit of the RAM.
2. Current Consumption
• For the MB89PV490 the current consumed by the EPROM mounted in the piggy-back socket is needed to be
included.
• When operating at low speed, the current consumed by the FLASH product is greater than that for the mask
ROM product. However, the current consumption is roughly the same in sleep and stop mode.
• For more information, see “Electrical Characteristics.”
3. Oscillation Stabilization Time after Power-on Reset
• For MB89PV490 and MB89F499, the power-on stabilization time cannot be selected.
• For MB89497 and MB89498, the power-on stabilization time can be selected.
• For more information, please refer to “Mask Option”.
