The following products are the flash memory versions of the V850/SA1.
In the instruction fetch to this flash memory, 4 bytes can be accessed by a single clock in the same way as the
Writing to flash memory can be performed with the memory mounted on the target system (on board). A dedicated
The following can be considered as the development environment and applications using flash memory.
• Software can be altered after the V850/SA1 is solder-mounted on the target system.
• Small scale production of various models is made easier by differentiating software.
• Data adjustment in starting mass production is made easier.
• 4-byte/1-clock access (in instruction fetch access)
• All area one-shot erase/area-unit erase (
• Communication via serial interface with the dedicated flash programmer
• Erase/write voltage: V
• On-board programming
• Flash memory programming by self-programming is possible in area units (128 KB) (all areas in the
The erasing unit differs depending on the product.

The area of xx000000H to xx01FFFFH can be erased in one shot.
If replacing a flash memory version with a mask ROM version when changing from trial
production to mass production, make a thorough evaluation by using the CS model (not ES
model) of the mask ROM version.
