Product details
Overview
TMS32C6416EGLZA5E0 from Texas Instruments is a fixed-point digital signal processor (DSP) built on the VelociTI.2™ VLIW architecture, delivering 500 MHz clock rate, 4000 MIPS performance, and integrated Viterbi/Turbo decoder coprocessors for real-time channel decoding in wireless baseband processing. It features 16KB L1P/L1D caches, 1024KB unified L2 RAM/cache, dual EMIFs (64-bit EMIFA + 16-bit EMIFB), and operates at 1.2-V core / 3.3-V I/O.
For engineers reviewing the TMS32C6416EGLZA5E0 datasheet, TMS32C6416EGLZA5E0 pinout, TMS32C6416EGLZA5E0 application, or TMS32C6416EGLZA5E0 equivalent, key selection criteria include its 532-pin GLZ BGA package, PCI 2.2 and UTOPIA Level 2 slave interface support, EDMA-controlled VCP/TCP offload capability, and software compatibility with C62x™ and C64x™ family.
Technical Context
The TMS32C6416EGLZA5E0 implements an eight-functional-unit VelociTI.2™ DSP core with six ALUs (supporting quad-8-bit/dual-16-bit/32-bit arithmetic) and two multipliers (enabling four 16×16-bit or eight 8×8-bit MACs/cycle). Its non-aligned load-store architecture and 64 × 32-bit general-purpose registers enable high-throughput data movement and packed-data processing.
It integrates dedicated hardware accelerators - the Viterbi Decoder Coprocessor (VCP) decodes >600 AMR 7.95-Kbps voice channels, and the Turbo Decoder Coprocessor (TCP) handles up to seven 2-Mbps or 43 × 384-Kbps 3GPP frames - both synchronized via 64-channel EDMA. Memory subsystem includes flexible L2 allocation (up to 256KB cache + remainder mapped RAM).

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-point DSP applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320C6416TGLZA7E3 | 720 MHz clock, 1.4-V core, 1.39-ns cycle time - 44% higher MIPS than TMS32C6416EGLZA5E0 | Targeted for higher-throughput 3GPP2 or LTE-Advanced baseband where VCP/TCP must handle >1000 AMR channels | Select when algorithm complexity exceeds 4000 MIPS budget and thermal/power envelope permits 1.4-V operation |
| TMS320C6415TGLZA6E3 | Lacks VCP/TCP coprocessors; same 600 MHz speed, 1.4-V core, and PCI/UTOPIA peripherals as C6416 variant | Suitable for non-channel-decoding roles (e.g., media gateway transcoding, radar pulse compression) requiring PCI/UTOPIA but no turbo/viterbi acceleration | Select when VCP/TCP functionality is unnecessary and cost reduction via part simplification is prioritized |
Compared with TMS32C6416EGLZA5E0, the TMS320C6416TGLZA7E3 delivers higher computational headroom for future-proofing, while the TMS320C6415TGLZA6E3 removes redundant accelerator logic to lower unit cost - both retain identical GLZ package, pinout, and peripheral set except VCP/TCP presence.

FAQ
What is the core voltage requirement for stable operation of the TMS32C6416EGLZA5E0?
The TMS32C6416EGLZA5E0 requires a nominal 1.2-V ±0.06-V core supply for guaranteed operation at its rated 500-MHz clock speed. This voltage is specified in the Recommended Operating Conditions table of the SPRS146N datasheet and must be tightly regulated with low-noise decoupling to prevent timing violations or thermal runaway during sustained VCP/TCP acceleration.
Does the TMS32C6416EGLZA5E0 support PCI Express or only legacy PCI?
The TMS32C6416EGLZA5E0 supports only PCI Specification 2.2 - a 32-bit, 33-MHz parallel bus interface - and does not implement PCI Express (PCIe) physical or link layers. Its PCI interface operates in both master and slave modes, with four-wire EEPROM configuration and programmable interrupt generation, as documented in section 113 of the SPRS146N datasheet.
Can the TMS32C6416EGLZA5E0 execute C62x™-compiled code without modification?
Yes, the TMS32C6416EGLZA5E0 is fully software-compatible with TMS320C62x™ devices at the assembly and object-code level due to architectural backward compatibility defined in the C6000™ platform roadmap. Existing C62x™ binaries run unmodified, though performance gains from VelociTI.2™ extensions (e.g., quad-8-bit ops) require recompilation with C64x™-optimized toolchain.
How many McBSPs are available on the TMS32C6416EGLZA5E0 and what protocols do they support?
The TMS32C6416EGLZA5E0 integrates three multichannel buffered serial ports (McBSP0–McBSP2), each supporting T1/E1 framing, MVIP, SCSA, AC97, SPI (Motorola™ format), and ST-Bus switching. Each McBSP handles up to 256 time-division multiplexed channels and can operate independently with separate clocks and frame syncs - enabling simultaneous audio, telephony, and control data streams.
Is the L2 memory on the TMS32C6416EGLZA5E0 cache-only or can it be used as raw RAM?
The 1024KB L2 memory on the TMS32C6416EGLZA5E0 is unified and fully configurable: it can be allocated entirely as mapped RAM, entirely as cache (up to 256KB), or as any combination thereof. This flexibility allows designers to prioritize deterministic access latency (RAM mode) or bandwidth efficiency (cache mode) based on real-time constraints - a key differentiator versus fixed-cache architectures.
