Texas Instruments TMS320VC5510AZGWA1

Overview

TMS320VC5510AZGWA1 from Texas Instruments is a fixed-point digital signal processor (DSP) based on the C55x architecture, operating at 200 MHz with 6.25-ns instruction cycle time. It integrates dual 17×17 multipliers (400 MMACS), 160K × 16-bit on-chip RAM (64K DARAM + 256K SARAM), 16K × 16-bit ROM, and a 24KB instruction cache. It serves as the real-time signal processing engine in portable audio codecs and telecom baseband subsystems.

For engineers reviewing the TMS320VC5510AZGWA1 datasheet, TMS320VC5510AZGWA1 pinout, TMS320VC5510AZGWA1 application, or TMS320VC5510AZGWA1 equivalent, key selection criteria include its 240-ball MicroStar BGA (ZGW) package, 3.3-V I/O / 1.6-V core supply, glueless EMIF support for SDRAM/SBSRAM, triple McBSPs for multichannel audio I/O, and programmable DPLL clock generation.

Technical Context

The TMS320VC5510AZGWA1 implements the C55x CPU core with a highly parallel bus architecture: 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 instruction control, supported by a 40-bit ALU and auxiliary 16-bit ALU.

On-chip peripherals include a 32-bit external memory interface (EMIF) with configurable timing for asynchronous SRAM/EPROM and synchronous SDRAM/SBSRAM, three full-duplex McBSPs supporting TI-AIC, I2S, and SPI protocols, and a 16-bit enhanced host-port interface (EHPI) configurable in multiplexed or non-multiplexed mode for host-DSP memory access.

FAQ

What is the maximum operating frequency of the TMS320VC5510AZGWA1?

The TMS320VC5510AZGWA1 operates at a maximum clock rate of 200 MHz, corresponding to a 6.25-ns instruction cycle time. This frequency is achieved using the on-chip digital phase-locked loop (DPLL) to multiply a lower-frequency external reference (e.g., 12.288 MHz). The device's electrical specifications guarantee timing compliance across the full temperature and voltage range when operated within recommended conditions.

Does the TMS320VC5510AZGWA1 support SDRAM interfacing?

Yes, the TMS320VC5510AZGWA1 supports SDRAM interfacing via its 32-bit external memory interface (EMIF). Section 5.7.3 of the SPRS076O datasheet specifies timing parameters for ACTV, REFR, MRS, and data-read/write commands. The EMIF provides dedicated SDRAM control signals (SDCKE, SDWE, SD CAS/RAS) and supports auto-precharge and burst-length configuration through EMIF registers.

How many McBSPs does the TMS320VC5510AZGWA1 include, and what protocols do they support?

The TMS320VC5510AZGWA1 includes three independent multichannel buffered serial ports (McBSP0–McBSP2). Each supports TI-AIC, I2S, left-justified, right-justified, and SPI master/slave modes. Configuration is performed via McBSP registers (SPCR1/SPCR2, PCR), and timing is validated per Tables 5–21 and 5–22 in SPRS076O for CLKSTP = 10b/11b and CLKXP = 0/1 combinations.

What is the purpose of the instruction cache in the TMS320VC5510AZGWA1?

The 24-KB instruction cache in the TMS320VC5510AZGWA1 reduces external memory accesses during repeated code execution, improving throughput and lowering system power. It operates transparently under hardware control, with cache line size and replacement policy defined in the C55x architecture manual. Cache hit rates exceed 92% in typical audio codec loops, as confirmed by Code Composer Studio profiling tools.

Is the TMS320VC5510AZGWA1 pin-compatible with other C55x family members?

No, the TMS320VC5510AZGWA1 is not pin-compatible with other C55x devices such as the TMS320VC5509A or TMS320C5517. Its 240-ball ZGW BGA package, EMIF bus width (32-bit vs. 16-bit), and peripheral signal allocation (e.g., triple McBSPs, 16-bit EHPI) are unique to the VC5510/5510A family. PCB layout must be designed specifically for the ZGW mechanical footprint and signal routing requirements.
