27.1 Features
The V850E/IF3 and V850E/IG3 have a 128 KB or 256 KB on-chip flash memory.
•
•
Flash memory can be rewritten with the flash memory programmer or using the self programming mode.
Writing to the flash memory programmer can be performed with the flash memory programmer that is connected to
Writing in the self programming mode can be performed with an application program, without using the flash
Flash memory versions are commonly used in the following development environments and mass production
μ
μ
All area batch erase or erase in block units (2 KB)
Communication through serial interface from the flash memory programmer
Erase/write voltage: Erase/write is possible with a single power supply
Flash memory self programming possible
Rewriting flash memory and read disable function supported (security enforced)
For altering software after the V850E/IF3 and V850E/IG3 is soldered onto the target system.
For differentiating software according to the specification in small scale production of various models.
For data adjustment when starting mass production.
On-board programming
Secure rewriting of entire flash memory area by self programming using boot swap function
Rewriting method
• Rewriting by communication with flash memory programmer via serial interface (on-board/off-board
• Rewriting flash memory by user program (self programming)
Interrupts can be acknowledged during self programming.
