23.3 Flash Memory Features
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 flash memory mounted on the
target system (on-board write). A flash memory writing adapter (program 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
23.3.1 Programming environment
The following shows the environment required for
PD178F098 flash memory programming.
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 to the manuals for Flashpro III/Flashpro IV.
Remark
USB is supported by Flashpro IV only.
