19.1 Flash Memory Characteristics

Flash memory programming is performed by connecting a dedicated flash programmer (Flashpro III (part no. FL-
PR3, PG-FP3)/Flashpro IV (part no. FL-PR4, PG-FP4)) to the target system with the
mounted on the target system (on-board). A flash memory program adapter (FA adapter), which is a target board used
exclusively for programming, is also provided.
Remark FL-PR3, FL-PR4, and the program adapter are products of Naito Densei Machida Mfg. Co., Ltd. (TEL
+81-45-475-4191).
Programming using flash memory has the following advantages.
• Software can be modified after the microcontroller is solder-mounted on the target system.
• Distinguishing software facilities low-quantity, varied model production
• Easy data adjustment when starting mass production

19.1.1 Programming environment

The following shows the environment required for
When Flashpro III (part no. FL-PR3, PG-FP3) or Flashpro IV (part no. FL-PR4, PG-FP4) is used as a dedicated
flash programmer, a host machine is required to control the dedicated flash programmer. Communication between the
host machine and flash programmer is performed via RS-232C/USB (Rev. 1.1).
For details, refer the manuals of Flashpro III/Flashpro IV.
Remark USB is supported by Flashpro IV only.
