Flash Development Module - FDM

The Flash Development Module (FDM) is a USB interface board used to control the mode and reset pins of the target device as well as providing USB<->Serial conversion. It can be used in conjunction with FDT for programming Renesas H8 and SH Flash microcontrollers via the PC USB port.

 

The FDM has been designed as a replacement for the Universal Programming Board (UPB) as supplied with first-generation Evaluation Boards, but using the host PC's USB interface instead of the serial port.

Features

  • Simple PC-USB plug’n’play programming of on-chip Flash
    • through standard MCU UART Boot mode.
  • Used by Renesas PC software tools:-
    • FDT v2.2 and v3.1Flash programming software
    • HEW v2.2 (HMon debugger, under consideration)
  • Can improve download speed (over PC-RS232 interface):-
    • Standard baud rates (115Kbaud)
    • non standard baud rates (300Kbaud)
    • clock-synchronous (under consideration) (2Mb/sec)
  • Suitable ALL H8 / SH MCU, 1.8 to 5V (even split voltage levels).
    • Algorithms are QA tested code
  • Fully automated Boot mode control and auto-sensing of connection.
  • Warns if supply voltage drifts from configurable limits.
  • Support
    • Initially FDT2.2 and 3.1, supports all new EDKs (14-way connector).
    • From FDT 3.1, configurable support for user’s own target board.
  • Uses PC USB interface
  • Includes support for low voltage devices (3.3 - 5.0V)
  • Target voltage follow circuitry for automatic adjustment to target voltage levels
  • Separate core (uVcc) and serial voltage (pVcc) support
  • In field self upgradability over USB for FDM firmware upgrading.
  • Autostart function on target voltage stability detection
  • Microsoft Windows™ 98, ME, 2000 or XP
  • (USB not fully supported under Windows 95 or Windows NT)
  • FDT 2.2 (Flash Development Toolkit) or above required (support for increased messaging, run-time selection of mode pin settings and
  • Multiple FDMs supported from FDT 3.1

 

Coming soon:

 

  • Support for non-standard baud rates planned in FDT for use with the FDM
  • Future support for fast FLASH programming planned Q4 2003
  • Support for clock synchronous communication planned in FDT for use with the FDM
