8-BIT SINGLE-CHIP MICROCONTROLLER
PRELIMINARY PRODUCT INFORMATION
Document No. U12240EJ1V0PM00 (1st edition)
Date Published May 1997 J
Printed in Japan
1997
The
μ
PD789405,
μ
PD789406, and
μ
PD789407 are
μ
PD789407 sub-series products (LCD drivers) of the 78K/0S
series.
These microcontrollers feature an 8-bit CPU, LCD controller/driver, I/O ports, timers, a serial interface, A/D
converters, and interrupt control circuits.
The instruction set of the
μ
PD789405,
μ
PD789406, and
μ
PD789407 is a subset of the 78K/0 series standard
instruction set.
In addition, a flash memory product (
μ
PD78F9418) that can operate within the same voltage range as the mask
ROM models, and a range of related development tools are being developed.
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.
