CHAPTER 27 FLASH MEMORY
The 78K0R/Lx3 microcontrollers incorporate the flash memory to which a program can be written, erased, and
overwritten while mounted on the board.
27.1 Writing with Flash Memory Programmer
Data can be written to the flash memory on-board or off-board, by using a dedicated flash memory programmer.
(1) On-board programming
The contents of the flash memory can be rewritten after the 78K0R/Lx3 microcontrollers have been mounted on the
target system. The connectors that connect the dedicated flash memory programmer must be mounted on the target
system.
(2) Off-board programming
Data can be written to the flash memory with a dedicated program adapter (FA series) before the 78K0R/Lx3
microcontrollers are mounted on the target system.
Remark The FA series is a product of Naito Densei Machida Mfg. Co., Ltd.
27.2 Programming Environment
The environment required for writing a program to the flash memory of the 78K0R/Lx3 microcontrollers are illustrated
below.

Dedicated flash
memory programmer
A host machine that controls the dedicated flash memory programmer is necessary.
To interface between the dedicated flash memory programmer and the 78K0R/Lx3 microcontrollers, the TOOL0 pin is
used for manipulation such as writing and erasing via a dedicated single-line UART. To write the flash memory off-board,
a dedicated program adapter (FA series) is necessary.
