PD789187,
μ
PD789196, and
μ
PD789197 are
μ
PD789187 and
μ
PD789197 sub-series products
of the 78K/0S series.
These microcontrollers feature an 8-bit CPU, I/O ports, timers, a serial interface, A/D converters, interrupt control
circuits, and EEPROM
In addition, a flash memory product (
μ
PD78F9198) that can operate within the same voltage range as the masked
ROM models, and a range of related development tools are being developed.
The functions of these microcontrollers are described in the following user’s manuals. Refer to these
manuals when designing a system based on any of these microcontrollers.
