Introduction
This document explains the interface specifications for “On-board connection” method
programming.
FP-30 has two connection methods that are used for programing flash memory:
On-board programming
SPI flash memory on a hardware boards can be programmed using this method.
The FP unit and the hardware board are connected using an adapter cable.
Off-board programming
Individual flash memory chips inserted into a socket adapter can be programmed
using this method. A variety of socket adapters for flash memory packages are
available to support this operation.

※
Please refer to the pin layout and be sure to confirm how to assign the pin number.
On-board programming example using
For On-board programming, it is recommended to use the adapter cable [ADP-FP30SA-CBL-S10] and to use
the ISP connector on the target board.
In case of hardware boards that have already been designed/manufactured without an ISP connector, a test
clip can be used to program the flash memory.
For details, refer to [Chapter 8 Interfacing with the hardware board (On-board connection)] in the FP-30 User’s
Manual.

Notes
Make sure to use the appropriate adapter for FP-30. Operation is only guaranteed if the appropriate adapter is
used.
The wire length between the ISP connector and SPI should be as short as possible. The shorter the better.
It is recommended to insert a damping resistor between the ISP connector and the SPI flash memory.

Signal specifications
The ISP interface signal specifications are explained here:
SRST signal
FP-30 unit outputs a “Low” on this signal to communicate with the SPI flash memory. Make sure that the SPI flash memory
signals are in high impedance state on the hardware board. The output from the FP-30 is open collector.
Vtref signal
The flash memory power supply voltage is output on this signal (1.8V~3.3V).
SPI signal (SCLK, CS1, SI/SIO0, SO/SIO1, SIO2, SIO3, CS2)
These signals are used by the flash memory. NC if not used.

8.4
Using a test clip in On-Board connection
For On-board programming, it is recommended to use the adapter cable [ADP-FP30SA-CBL-S10]and to use the ISP connector
on the target board.
In case of hardware boards that have already been designed/manufactured without an ISP connector, a test clip can be used to
program the flash memory. This procedure is described in this section.
It is recommended to use the supplied adapter cable [ADP-FP30SA-CBL-S10]
with the ISP connector whenever possible. The method described here is not
guaranteed to work always. Incorrect wiring may cause damage to the board or to
the flash memory and the FP-30 unit.
Follow this method at your own risk.

Tips for connecting
・The cable length between FP-30 and the hardware board should be 20cm
or less. The shorter the better.
・The communication is stable at a slower clock speeds.
・Using one I/O data line is stable than using four.
・In additional to SPI signal lines, it is required to connect the SRST (Pin 19:
System reset signal). Note that this signal is not the SPI flash reset signal.
Info.

FP-30 User’s Manual Chapter 8 Interfacing with the hardware board (On-board connection) 89
8.5
Supplying power to target from FP-30
Power can be supplied from FP-30 to the hardware board using the adapter cable [ADP-FP30SA-CBL-S10]Rev 0-A and
[C-Flash for SPI] Ver. 1.05.00 or later. Flash memory on hardware boards with a light load can be written to without having to
supply external power.
Depending on various factors, some boards might still need an external power
supply. Refer to the board manual for details.
Incorrect connection may damage the target board and the FP-30 unit. Follow this
method at your own risk.
8.5.1
Check the revision of the adapter cable
Make sure the adapter revision is Rev 0-A before proceeding. The revision can be checked as explained in section “7.2.2
Hardware revision”.

・The option [Supply power to the target from FP-30] has to be checked on the “On-board settings tab” of the
Detailed settings dialog.
・Ensure that power is supplied to the hardware board only through FP-30 and no other power supply sources are used.
・The current consumption of the hardware board must be less than the max current supported by the FP-30 unit.

C-Flash settings
External I/O signals have to be configured on the [External Input/Output settings tab]on the Detailed settings dialog.
After the settings are done, the [Write] button on C-Flash has to be clicked to configure the FP-30 unit to use these settings. Note
that these settings will come to effect only after the [Write] button is clicked.

FP-30 User’s Manual Chapter 16 External I/O functions 130
16.2.1
EXSTARTOUT signal
LOW is output on the EXSTARTOUT signal when the [PROGRAM]button on the FP-30 unit is pressed. It is in high impedance
state otherwise.
When two or more FP-30 units are used, the EXSTARTOUT signal can be connected to the EXSTART signal. When the
[PROGRAM]button on the first FP-30 unit is pressed, subsequent FP-30 units will also begin the write process. In this way
multiple units can be controlled with a single button press.
EXSTARTOUT signal is always output and there are no settings on C-Flash to disable it.
16.2.2
EXSTART signal
EXSTART signal can be used instead of the [PROGRAM]button on the FP-30 unit to begin the write operation.
As explained before, multiple FP-30 units can be controlled with a single button press by connecting the EXSTARTOUT signal of
one unit to the EXSTART signal of another.
To use this signal, choose [Enabled] under [EXSTART - External Write start signal (input)]group on the [External
Input/Output settings tab]on the Detailed settings dialog.
When EXSTART signal is enabled, write operation is started when a low level is detected on this line. During write operation,
EXSTART is ignored.

FP-30 User’s Manual Chapter 16 External I/O functions 131
16.2.3
EXOK signal
The status of write operation can be determined using EXOK signal. There are 3 patterns that can be selected from under
[EXOK - External OK signal (output)]group on the [External Input/Output settings tab]on the Detailed settings dialog.
①Low on success, Hi-Z on fail
On success
On fail
②Pulse output during write, Low on success, Hi-Z on fail
On success
On fail

FP-30 User’s Manual Chapter 16 External I/O functions 132
③Low during write, Hi-Z after write
When the write process is in progress, Low is output on EXOK. After write terminates a Hi-Z is output irrespective of whether the
write operation succeeds or fails.
16.2.4
EXNG signal
Success or failure of write operation can be determined using this signal. A low is output during write operation and write
success, and high on failure.
To use this signal, choose [Enabled(Hi-Z on success, Low on fail)]under [EXNG - External result signal (output)]
group on the [External Input/Output settings tab]on the Detailed settings dialog.
On success
On fail
