Texas Instruments TMS320VC5501ZZZ300

Overview

TMS320VC5501ZZZ300 from Texas Instruments is a fixed-point digital signal processor (DSP) with 300 MHz CPU clock, 128K × 16-bit on-chip dual-access RAM (DARAM), and integrated peripherals including McBSP, UART, I²C, HPI, and DMA. It executes up to 600 MIPS and targets real-time audio processing, telecom infrastructure, and industrial control systems requiring deterministic low-latency signal computation.

For engineers reviewing the TMS320VC5501ZZZ300 datasheet, TMS320VC5501ZZZ300 pinout, TMS320VC5501ZZZ300 application, or TMS320VC5501ZZZ300 equivalent, key selection criteria include its 201-ball BGA (ZXX package), 3.3-V I/O compatibility, PLL-based clock generation supporting 300-MHz core operation, and boot-from-external-memory capability via parallel host port or serial interface.

Technical Context

The TMS320VC5501ZZZ300 implements a dual-MAC, 16-bit fixed-point VLIW architecture with instruction cache and memory-mapped peripherals. Its memory subsystem includes 32K × 16-bit on-chip ROM, 128K × 16-bit DARAM, and configurable external memory interface (EMIF) supporting asynchronous SRAM, synchronous SDRAM, and programmable synchronous devices.

Peripherals are tightly coupled via internal buses: two multichannel buffered serial ports (McBSPs) support TDM, I²S, and SPI modes; the 16-bit host-port interface (HPI) enables direct memory access from an external controller; and the six-channel DMA controller offloads data movement from the CPU during intensive signal buffering operations.

Key Specifications

Pinout & Package

The TMS320VC5501ZZZ300 uses a 201-ball, 15 × 15 mm, 0.8-mm pitch ball grid array (BGA) package designated ZZZ per TI's packaging nomenclature. Ball assignment follows JEDEC MO-220 standard with power/ground distribution optimized for low-noise DSP operation.

FAQ

What is the maximum operating frequency of the TMS320VC5501ZZZ300?

The TMS320VC5501ZZZ300 operates at a maximum CPU clock frequency of 300 MHz, delivering up to 600 million instructions per second (MIPS). This speed is achieved using an internal phase-locked loop (PLL) that multiplies a 1–20 MHz external reference clock. The device maintains timing integrity across its entire memory and peripheral subsystem at this rated frequency under recommended operating conditions (3.3-V I/O, 1.6-V core, 0°C to 70°C ambient).

Does the TMS320VC5501ZZZ300 support booting from external memory?

Yes, the TMS320VC5501ZZZ300 supports booting from external memory via its 16-bit host-port interface (HPI), serial EEPROM (using SPI-compatible pins), or parallel external memory mapped through the EMIF. Boot mode is selected at reset using GPIO6 and other strap pins. The on-chip ROM contains bootloader code that initializes the EMIF or HPI and copies application code into internal DARAM before execution begins.

What types of external memory does the TMS320VC5501ZZZ300 EMIF support?

The TMS320VC5501ZZZ300 external memory interface (EMIF) supports asynchronous SRAM, synchronous SDRAM (including auto-refresh and MRS commands), and programmable synchronous devices such as NOR flash and FPGA configuration memory. Timing parameters - including setup/hold, access, and turn-around - are fully configurable via EMIF control registers to accommodate diverse memory vendors and speed grades without hardware changes.

How many serial communication interfaces does the TMS320VC5501ZZZ300 integrate?

The TMS320VC5501ZZZ300 integrates three dedicated serial interfaces: two multichannel buffered serial ports (McBSP0 and McBSP1), one universal asynchronous receiver/transmitter (UART), and one inter-integrated circuit (I²C) module. Each McBSP supports TDM, I²S, and SPI master/slave modes with independent clock and frame sync generation; the UART provides full-duplex RS-232/RS-485 compatible framing; and the I²C module handles sensor and EEPROM configuration at standard (100 kHz) and fast (400 kHz) modes.

Is JTAG debugging supported on the TMS320VC5501ZZZ300?

Yes, the TMS320VC5501ZZZ300 includes full IEEE 1149.1-compliant JTAG boundary scan capability for emulation, in-circuit debugging, and flash programming. The TCK, TMS, TDI, TDO, and TRST pins are dedicated and electrically isolated from functional I/O. Texas Instruments' Code Composer Studio (CCS) and XDS510-class emulators provide real-time breakpoint, watchpoint, and memory inspection support directly through the JTAG interface.
