S5U13513P00C100 Evaluation Board
Rev. 1.2
The S5U13513P00C100 evaluation board is designed to connect to a S5U13U00P00C100
USB Adapter Board. The USB adapter board provides a simple connection to any computer
via a USB 2.0 connection. The S5U13513P00C100 directly connects to the adapter board
through connectors P1 and P2. The USB adapter board also supplies the 3.3V power
required by the S5U13513P00C100.
The S5U13513P00C100 evaluation board may be connected to an Epson PC Card Extender
Board, but it will require an external 3.3V power supply and some modifications to the
S5U13513P00C100 board.
The modifications required for the S5U13513P00C100 board are:
1. Remove R107 and R108 (0 ohm resistors, size 0603)
2. Remove R109 and R112 (0 ohm resistors, size 0402)
3. Populate R110 and R111 with 0 ohm resistors, size 0402 (or short the pads on the
board)
4. Set DIP switch SW1-[5:1] to 00100b (CNF[4:0]=00100b) to select Parallel Direct 80
Type 1: 1CS# host interface
To use a modified S5U13513P00C100 with an Epson PC Card Extender board:
1. Connect the 2 boards using connectors P1 and P2.
2. Connect 3.3V power supply to the S5U13513P00C100. Connect the positive of the
power supply to test point TP3.3VDD1, and the negative to test point TPGND2
3. Plug the PC Card Extender (with S5U13513P00C100 connected to it) into a PC Card
slot on a PC.
4. Turn on the 3.3V power supply and the S5U13513P00C100 is ready to use. Note that
a windows driver is required to be installed on the PC (the S1D13xxx PCI/PC Card
Bus driver is available from vdc.epson.com).
