Introduction

April 2004 − Revised January 2008

SPRS245J

The 5503 is supported by the industry’s award-winning eXpressDSP

, Code Composer Studio Integrated

Development Environment (IDE), DSP/BIOS

, Texas Instruments’ algorithm standard, and the industry’s

largest third-party network. The Code Composer Studio IDE features code generation tools including a

C Compiler and Visual Linker, simulator, RTDX

, XDS510 emulation device drivers, and evaluation

modules. The 5503 is also supported by the C55x DSP Library which features more than 50 foundational

software kernels (FIR filters, IIR filters, FFTs, and various math functions) as well as chip and board support

libraries.

Pin Assignments

Figure 2−1 illustrates the ball locations for the 179-pin ball grid array (BGA) package and is used in conjunction

with Table 2−1 to locate signal names and ball grid numbers.

DVDD is the power supply for the I/O pins while CVDD is the power supply for the core. VSS is the ground for

both the I/O pins and the core. RCVDD and RDVDD are RTC module core and I/O supply, respectively.
