8-BIT SINGLE-CHIP MICROCONTROLLER
PRELIMINARY PRODUCT INFORMATION
MOS INTEGRATED CIRCUITS
μ
PD78F9136
The
μ
PD78F9136 is
μ
PD789134 sub-series products of the 78K/0S series.
The
μ
PD78F9136 differs from the
μ
PD789131,
μ
PD789132, and
μ
PD789134 in that it uses flash memory
rather than internal masked ROM. Flash memory can be written or erased electrically without having to remove it
from board. Therefore, the
μ
PD78F9136 is best suited for prototypes in system development, low-volume
production, or systems likely to be upgraded frequently.
The functions of these microcontrollers are described in the following user's manual. Refer to this
manual when designing a system based on any of these microcontrollers.
