10-Pin Connector

The S3 Flash In-System Programmer connects to the S3 Family Development Board (or

other target board with an S3 device) using a 10-pin ribbon cable and 2x5 female connec-

tors. Pin 1 of this cable is marked by a red wire. An S3 Flash ISP male connector is

required on the target system; it is a 2x5 header with standard 0.025-inch square posts on

0.100 inch centers, the same as headers commonly used for jumper blocks. The connector

used on all S3 development boards is FCI part number 67997-210HLF.

Figure 2 shows the connections between the ISP connector and the S3 Flash MCU. When

connecting the ribbon cable to your target board, ensure that you align Pin 1 of the cable

with Pin 1 of the connector on the board.

ISP Interface

The S3 Flash ISP interface consists of the following signals:

TEST/V

. Test Mode signal; when driven High, this signal places the S3 Flash MCU into

Test Mode to make on-chip Flash memory available for access by the S3 Flash ISP. Ensure

that you place a 0.1 µF capacitor and 10KOhm resistor between this pin and Ground, as

shown in Figure 2.
