Texas Instruments TMS320VC5510AZGWA2

Overview

TMS320VC5510AZGWA2 from Texas Instruments is a fixed-point digital signal processor (DSP) based on the C55x CPU core, delivering 200-MHz operation at 5-ns instruction cycle time, dual 17×17 multipliers (400 MMACS), 160K × 16-bit on-chip RAM (64K DARAM + 256K SARAM), and 16K × 16-bit ROM. It targets real-time audio processing, telecom baseband, and industrial control systems requiring deterministic low-latency signal computation.

For engineers reviewing the TMS320VC5510AZGWA2 datasheet, TMS320VC5510AZGWA2 pinout, TMS320VC5510AZGWA2 application, or TMS320VC5510AZGWA2 equivalent, key selection criteria include EMIF glueless support for SDRAM/SBSRAM, three McBSPs with SPI master/slave capability, EHPI parallel host interface, programmable DPLL clock generation, and 1.6-V core / 3.3-V I/O supply compatibility.

Technical Context

The TMS320VC5510AZGWA2 implements a highly parallel C55x architecture with one program bus, three data read buses, and two data write buses-enabling up to three simultaneous data reads and two writes per cycle. Its dual MAC units operate independently under full instruction-set control, supported by a 40-bit ALU and auxiliary 16-bit ALU.

On-chip peripherals include a 32-bit external memory interface (EMIF) supporting asynchronous SRAM/EPROM and synchronous SDRAM/SBSRAM; three full-duplex McBSPs configurable as SPI masters or slaves; a 16-bit enhanced host-port interface (EHPI) in multiplexed or non-multiplexed mode; six-channel DMA; two 20-bit timers; eight GPIO pins; and a programmable digital PLL for flexible clock synthesis.

FAQ

What is the maximum operating frequency of the TMS320VC5510AZGWA2?

The TMS320VC5510AZGWA2 operates at a maximum clock rate of 200 MHz, corresponding to a 5-ns instruction cycle time. This frequency is achieved using the on-chip digital phase-locked loop (DPLL) to multiply a lower-frequency external crystal or oscillator input. The device's electrical specifications guarantee stable operation at this speed under recommended case temperature and supply voltage conditions (1.6-V core, 3.3-V I/O).

Does the TMS320VC5510AZGWA2 support synchronous DRAM (SDRAM)?

Yes, the TMS320VC5510AZGWA2 supports synchronous DRAM via its 32-bit external memory interface (EMIF) with dedicated SDRAM control signals (RAS, CAS, WE, CS). Timing parameters-including ACTV, REFR, MRS, and DCAB commands-are fully specified in the datasheet (Section 5.7.3), enabling glueless interface to standard 133-MHz SDRAM devices without external logic.

How many multichannel buffered serial ports (McBSPs) does the TMS320VC5510AZGWA2 include?

The TMS320VC5510AZGWA2 includes three independent multichannel buffered serial ports (McBSP0–McBSP2). Each supports full-duplex operation, TDM, I2S, and SPI master/slave modes with configurable clock polarity, frame sync, and data word length. All three McBSPs can operate concurrently, enabling simultaneous audio capture, playback, and host communication in systems like VoIP gateways.

What type of on-chip memory does the TMS320VC5510AZGWA2 provide?

The TMS320VC5510AZGWA2 provides 160K × 16-bit on-chip RAM composed of eight 4K × 16-bit dual-access RAM (DARAM) blocks (64K bytes) and thirty-two 4K × 16-bit single-access RAM (SARAM) blocks (256K bytes), plus 16K × 16-bit ROM (32K bytes). The DARAM enables simultaneous read/write access critical for ping-pong buffering in real-time streaming applications.

Is the TMS320VC5510AZGWA2 pin-compatible with other C55x family members?

No, the TMS320VC5510AZGWA2 is not pin-compatible with other C55x devices such as the TMS320VC5509A or TMS320C5517. It uses a unique 240-ball ZGW MicroStar BGA package with specific ball assignments for its EMIF, McBSPs, and EHPI. Migration requires PCB redesign; functional compatibility exists at the software level via C55x instruction set and CSL libraries, but hardware interface mapping is not interchangeable.
