UG-277 Datasheet, PDF (5/24 Pages) Analog Devices – SDP-B Controller Board

SDP User Guide
HARDWARE DESCRIPTION
This section describes the hardware design of the EVAL-SDP-
CB1Z board.
The following topics are covered:
• LEDs—This section describes the SDP on-board LEDs.
• Connector Details—This section details the pin
assignments on the 120-pin connectors.
• Power—This section lists power requirements of the SDP
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.
• Mechanical specifications—This section provides
dimensional information.
LEDS
There are two LEDs located on the SDP-B board (see Figure 2).
POWER LED
The green power LED indicates that the SDP-B board is
powered. This is not an indication of USB connectivity between
the SDP-B and the PC.

STATUS LED
The orange status LED is an LED used as a diagnostic tool for
evaluation application developers. When there are two or more
identical SDP controller board and daughter board combin-
ations connected to the PC simultaneously, the status LED
flashes during the connect routine to help the user identify
which board they will communicate with.
CONNECTOR DETAILS
The SDP-B board contains three Hirose FX8-120P-SV1(91),
120-pin header connectors. Connector A and Connector B share
identical pinouts and through these connectors, the peripheral
communication interfaces of ADSP-BF527 Blackfin processor are
exposed. The exposed peripherals are
• SPI
• SPORT
• I²C/TWI
• GPIO
• Asynchronous parallel
• PPI
• UART
• Timers
In addition, included on the connector specification are input
and output power pins, ground pins, and pins reserved for
future use. For further details on the peripheral interfaces,
including timing diagrams, see the ADSP-BF52x Blackfin
Processor Hardware Reference.
Connector C exposes the entire Blackfin memory space, but is
not used as part of the SDP platform.
Connector Pin Assignments
The connector pin assignments for Connector A and
Connector B have been defined independently of the any
internal pin sharing that occurs on the Blackfin processor.
Table 1 lists the connector pins and identifies the functionality
assigned to each connector pin for Connector A and
Connector B on the SDP-B board.
