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.
