EVALUATION BOARD HARDWARE

This section describes the hardware design of the EVAL-SDP-

CS1Z board.

The following topics are covered:

•

LEDs—This section describes the SDP-S on-board LEDs.

•

Connector details—This section details the pin

assignments on the 120-pin connector.

•

Power—This section lists power requirements of the SDP-S

and identifies connector power inputs and output pins.

•

Daughter board design guidelines—This section provides

guidelines on how to design daughter boards for use with

the SDP-S.

•

Mechanical specifications—This section provides

dimensional information.

LEDS

There are two LEDs located on the SDP-S board (see Figure 3).

Power LED (PWR)

The green power LED indicates that the SDP-S board is

powered. This is not an indication of USB connectivity between

the SDP-S and the PC.

The orange LED is an LED used as a diagnostic tool for

evaluation application developers.

CONNECTOR DETAILS

The SDP-S board contains one Hirose FX8-120P-SV1(91),

120-pin header connector. Through this connector, the

peripheral communication interfaces of the USB-to-serial

engine are exposed. The exposed peripherals are

•

SPI

•

•

GPIO

Also included on the connector specification are input and out-

put power pins, ground pins, and pins reserved for future use.

Connector Pin Assignments

Table 1 lists the connector pins and identifies the functionality

assigned to each connector pin on the SDP-S board.

The pinout of this connector is consistent with other connectors

across the SDP family.
