Introduction

This section describes the main features of the TMS320VC5441 digital signal processor (DSP), lists the pin

assignments, and describes the function of each pin. This data manual also provides a detailed description

section, electrical specifications, parameter measurement information, and mechanical data about the

available packaging.

NOTE: This data manual is designed to be used in conjunction with the TMS320C54x

 DSP Functional

Overview (literature number SPRU307).

Description

The TMS320VC5441 fixed-point digital signal processor is a quad-core solution running at 532-MIPS

performance. The 5441 consists of four DSP subsystems with shared program memory. Each subsystem

consists of one TMS320C54x

 DSP core, 32K-word program/data DARAM, 64K-word data DARAM, three

multichannel buffered serial ports, DMA logic, one watchdog timer, one general-purpose timer, and other

miscellaneous circuitry.

The 5441 also contains a host-port interface (HPI) that allows the 5441 to be viewed as a memory-mapped

peripheral to a host processor.

Each subsystem has its separate program and data spaces, allowing simultaneous accesses to program

instructions and data. Two read operations and one write operation can be performed in one cycle. Instructions

with parallel store and application-specific instructions can fully utilize this architecture. Furthermore, data can

be transferred between program and data spaces. Such parallelism supports a powerful set of arithmetic,

logic, and bit-manipulation operations that can all be performed in a single machine cycle. The 5441 includes

the control mechanisms to manage interrupts, repeated operations, and function calls. In addition, the 5441

has a total of 256K words of shared program memory (128K words shared by subsystems A and B, and

another 128K words shared by subsystems C and D).

The 5441 is intended as a high-performance, low-cost, high-density DSP for remote data access or voice-over

IP subsystems. It is designed to maintain the current modem architecture with minimal hardware and software

impacts, thus maximizing reuse of existing modem technologies and development efforts.

The 5441 is offered in two temperature ranges and individual part numbers are shown below. (Please note

that the industrial temperature device part numbers do not follow the typical numbering tradition.)

Commercial temperature devices (0

°C to 85°C)

TMS320VC5441PGF532 (176-pin LQFP)

TMS320VC5441GGU532 (169-ball BGA)

Industrial temperature range devices (−40

°C to 100°C)

TMS320VC5441APGF532 (176-pin LQFP)

TMS320VC5441AGGU532 (169-ball BGA)

NOTE: Leading “x” in signal names identifies the subsystem; x = A, B, C, or D for subsystem A, B, C,

or D, respectively. Trailing “n” in signal names identifies the McBSP; n = 0, 1, or 2 for McBSP0, McBSP1,

or McBSP2, respectively.
