Texas Instruments TMS320VC5510AGGWA2

Overview

TMS320VC5510AGGWA2 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 MAC units (400 MMACS), 160K × 16-bit on-chip RAM (64K DARAM + 256K SARAM), and 16K × 16-bit ROM - deployed in real-time audio processing, telecom baseband, and industrial motor control systems.

For engineers reviewing the TMS320VC5510AGGWA2 datasheet, TMS320VC5510AGGWA2 pinout, TMS320VC5510AGGWA2 application, or TMS320VC5510AGGWA2 equivalent, key selection considerations include EMIF glueless support for SDRAM/SBSRAM, three McBSPs with SPI master/slave capability, EHPI parallel host interface, DPLL clock synthesis, and 1.6-V core / 3.3-V I/O supply partitioning.

Technical Context

The TMS320VC5510AGGWA2 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 instruction control, while the 40-bit ALU and auxiliary 16-bit ALU are managed by dedicated address and data units.

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 clock generation.

FAQ

What is the maximum operating frequency of the TMS320VC5510AGGWA2?

The TMS320VC5510AGGWA2 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 synthesize the core clock from a lower-frequency external source (e.g., 12.288 MHz). The 200-MHz rating is validated across the specified temperature and voltage ranges per the SPRS076O datasheet.

Does the TMS320VC5510AGGWA2 support synchronous DRAM (SDRAM)?

Yes, the TMS320VC5510AGGWA2 supports SDRAM via its 32-bit external memory interface (EMIF) with built-in SDRAM controller logic. It handles row activation, precharge, refresh, and mode register setup autonomously-requiring no external glue logic. Timing compliance is verified per JEDEC standards, and configuration is controlled through EMIF registers (e.g., SDRAMCR, SDRAMPRE) defined in Section 3.12 of the SPRS076O manual.

How many multichannel buffered serial ports (McBSPs) does the TMS320VC5510AGGWA2 include?

The TMS320VC5510AGGWA2 integrates three independent multichannel buffered serial ports (McBSP0, McBSP1, McBSP2). Each supports full-duplex operation, TI-specific, I2S, SPI, and TDM protocols, with programmable clock polarity, frame sync width, and word length. All three McBSPs are fully functional in the TMS320VC5510AGGWA2 and documented in Sections 3.2.4 and 5.14 of SPRS076O.

What power supply voltages are required for the TMS320VC5510AGGWA2?

The TMS320VC5510AGGWA2 requires two distinct supply rails: a 1.6-V core supply (CVDD) for the CPU and internal logic, and a 3.3-V I/O supply (DVDD) for all external interface pins including EMIF, McBSPs, EHPI, and GPIO. These supplies must be sequenced correctly-CVDD must be stable before DVDD-and decoupled per TI's recommended layout in Section 6.2 of SPRS076O.

Is the TMS320VC5510AGGWA2 pin-compatible with other C55x family members?

No, the TMS320VC5510AGGWA2 is not pin-compatible with other C55x devices such as the TMS320VC5509A or TMS320C5517. It uses a unique 240-ball MicroStar BGA (GGW) package with specific ball assignments defined in Table 2−1 of SPRS076O. Pin mappings for EMIF, McBSPs, and EHPI differ across variants, and no official drop-in replacement documentation exists for this part.
