Texas Instruments TMS32C6416EGLZA6E3

Overview

TMS32C6416EGLZA6E3 from Texas Instruments is a high-performance fixed-point digital signal processor (DSP) featuring a 600-MHz C64x™ VelociTI.2™ VLIW core, 1024KB L2 unified RAM/cache, dual external memory interfaces (64-bit EMIFA + 16-bit EMIFB), and integrated Viterbi/Turbo decoder coprocessors (VCP/TCP) for real-time channel decoding in wireless baseband processing.

For engineers reviewing the TMS32C6416EGLZA6E3 datasheet, TMS32C6416EGLZA6E3 pinout, TMS32C6416EGLZA6E3 application, or TMS32C6416EGLZA6E3 equivalent, key selection criteria include its 600-MHz clock rate, 4800 MIPS throughput, 532-pin GLZ BGA package with 0.8-mm pitch, PCI 2.2 interface support, and hardware-accelerated 3GPP-compliant turbo/Viterbi decoding capability.

Technical Context

The TMS32C6416EGLZA6E3 implements an eight-functional-unit VelociTI.2™ VLIW core with six ALUs and two multipliers-each multiplier delivering four 16×16-bit or eight 8×8-bit MACs per cycle-enabling up to 4800 MMACS at 600 MHz. Its non-aligned load-store architecture supports byte/half-word/word/doubleword addressing with full conditional execution.

It integrates dedicated hardware accelerators: the VCP decodes >600 AMR voice channels (7.95 Kbps, K=9, R=1/3), while the TCP handles up to seven 2-Mbps or 43 × 384-Kbps 3GPP turbo frames (6 iterations), both communicating via 64-channel EDMA. The device uses a flexible L1/L2 memory hierarchy (16KB L1P, 16KB L1D, 1024KB L2) with configurable cache/mapped allocation.

FAQ

What is the core voltage requirement for TMS32C6416EGLZA6E3?

The TMS32C6416EGLZA6E3 requires a 1.4-V nominal core supply (VDD) and 3.3-V I/O supply (VDDIO), per the recommended operating conditions in SPRS146N. This 1.4-V core voltage supports its 600-MHz operation and distinguishes it from the 1.2-V/1.25-V variants used in lower-speed C6416 devices. Proper sequencing-core before I/O-is mandatory to avoid latch-up.

Does TMS32C6416EGLZA6E3 support PCI Express or only legacy PCI?

TMS32C6416EGLZA6E3 supports only PCI Specification 2.2 (32-bit/33-MHz), not PCI Express. Its PCI interface operates as master or slave, with three address registers (prefetchable memory, non-prefetchable memory, I/O) and programmable interrupt control. No PCIe PHY or link training logic is present - migration to PCIe requires external bridge ICs.

Can the L2 memory on TMS32C6416EGLZA6E3 be used exclusively as cache?

No - the 1024KB L2 memory on TMS32C6416EGLZA6E3 cannot be used exclusively as cache. It is a unified mapped RAM/cache resource with maximum configurable cache size of 256 KB; the remainder must be allocated as mapped RAM. This architecture ensures deterministic access latency for real-time buffers while retaining cache benefits for instruction/data hotspots.

How many McBSP ports does TMS32C6416EGLZA6E3 include, and are they all available simultaneously?

TMS32C6416EGLZA6E3 includes three multichannel buffered serial ports (McBSP0, McBSP1, McBSP2), all available simultaneously. However, McBSP1 shares pins with the UTOPIA interface; UTOPIA must be disabled in configuration to use McBSP1. Pin multiplexing is controlled via BEA[9:7] strap pins and device configuration registers during boot.

Is TMS32C6416EGLZA6E3 pin-compatible with TMS320C6414 or TMS320C6415 devices?

Yes - TMS32C6416EGLZA6E3 is pin-for-pin compatible with TMS320C6414 and TMS320C6415 in the same GLZ package, provided peripheral selection matches: PCI and UTOPIA must be disabled on C6415/C6416 to match C6414's pinout, and BEA[9:7] pins must be correctly strapped per device configuration guidelines in SPRS146N Section 6.
