About This Manual
This document describes the board level operations of the TMS320VC5505
Evaluation Module (EVM). The EVM is based on the Texas Instruments
TMS320VC5505 Digital Signal Processor.
The TMS320VC5505 EVM is a table top card to allow engineers and software
developers to evaluate certain characteristics of the TMS320VC5505 DSP to
determine if the processor meets the designers application requirements. Evaluators
can create software to execute on board or expand the system in a variety of ways.
The TMS320VC5505 EVM can be used to develop TMS320VC5504 applications since
the TMS320VC5504 processor is a subset of the TMS320VC5505.
Notational Conventions
This document uses the following conventions.
The TMS320VC5505 will sometimes be referred to as the C55XX.
The TMS320VC5505 EVM will sometimes be referred to as the EVM.

1.1 Key Features
The VC5505 EVM is a standalone development platform that enables users to
evaluate and develop applications for the TI TMS320VC5505 Digital Signal Processor
(DSP). The EVM also serves as a hardware reference design for the TMS320VC5505
DSP. Schematics, logic equations and application notes are available to ease
hardware development and reduce time to market.
The EVM comes with a full complement of on-board devices that suit a wide
variety of application environments. Key features include:
• A Texas Instruments TMS320VC5505 operating up to 100 Mhz.
• Flexible/variable power supply for each VC5505 power rail and scalable
power supply core
• TLV320AIC3254 stereo codec
• MMC / SD connector
• User USB port via VC5505
Figure 1-1, TMS320VC5505 EVM

Spectrum Digital, Inc

• I2C EEPROM (256Kbits) and SPI EEPROM (256Kbits)
• EMIF, I2S, I2S, UART, SPI interfaces on expansion connectors
• External JTAG emulation interface
• Embedded JTAG controller
• Color LCD Display
• 10 User push button switches
1.2 Development Tools
The EVM is designed to work with TI’s Code Composer Studio (CCS) Integrated
Development Environment (IDE). Code Composer Studio communicates with the EVM
board through the external emulator header, or on board emulation. An EVM specific
version of Code Composer Studio ships with the EVM.
1.3 Memory Map
Refer to the TMS320VC5505 device documentation for a more specific memory
information on the VC5505 device.
1.4 Power Supply
The EVM operates from a +5V external power supply or battery.
1.5 VC5505 GIO Schedule
The VC5505 has multiple GIO signals that can be used for system level tasks. The GIO
signals are connected to various jumpers on the EVM. By using jumper plugs, these
GIO signals can be used to control different functions on the VC5505 EVM. Refer to the
discussion of the jumper setting later in this document for details of the jumper locations
and options they provide. The table below describes how the GIO lines are used on the
EVM.
