Flash memory versions offer the following advantages for development environments and mass production applications.
{ For altering software after the V850ES/JG3-H and V850ES/JH3-H are soldered onto the target system.
{ For data adjustment when starting mass production.
{ For differentiating software according to the specification in small scale production of various models.
{ For facilitating inventory management.
{ For updating software after shipment.
31.1 Features
{ 4-byte/1-clock access (when instruction is fetched)
{ Capacity: 256/384/512 KB
{ Rewrite voltage: Erase/write with a single power supply
{ Rewriting method
• Rewriting by communication with dedicated flash programmer via serial interface (on-board/off-board
programming)
• Rewriting flash memory by user program (self programming)
{ Flash memory rewrite prohibit function supported (security function)
{ Safe rewriting of entire flash memory area by self programming using boot swap function
{ Interrupts can be acknowledged during self programming.
