Product details
Overview
TMS320C6416TBGLZ6 from Texas Instruments is a 1-GHz fixed-point digital signal processor (DSP) with VelociTI.2 VLIW architecture, eight functional units, 64 general-purpose registers, and dual on-chip coprocessors (VCP and TCP) for real-time wireless channel decoding. It delivers 8000 MIPS and 8000 MMACS, targeting baseband processing in 3G/UMTS infrastructure equipment.
For engineers reviewing the TMS320C6416TBGLZ6 datasheet, TMS320C6416TBGLZ6 pinout, TMS320C6416TBGLZ6 application, or TMS320C6416TBGLZ6 equivalent, key selection criteria include its 1-GHz clock rate, integrated VCP/TCP acceleration for AMR and 3GPP turbo decoding, dual EMIFs (64-bit + 16-bit), PCI 2.2 interface, and 532-pin GLZ BGA package with 0.8-mm pitch.
Technical Context
The TMS320C6416TBGLZ6 implements a two-level memory hierarchy: 16KB L1P direct-mapped cache, 16KB L1D 2-way set-associative cache, and 1024KB flexible L2 unified RAM/cache. Its CPU executes up to eight 32-bit instructions per cycle using non-aligned load-store architecture and conditional execution across all instructions.
It integrates application-specific hardware including Viterbi Decoder Coprocessor (VCP) supporting >833 × 7.95-Kbps AMR channels and Turbo Decoder Coprocessor (TCP) handling up to 10 × 2-Mbps or 60 × 384-Kbps 3GPP frames - both programmable in constraint length, code rate, and iteration count, with EDMA-managed data transfer to/from CPU memory space.
Key Specifications

FAQ
What is the maximum operating temperature specification for the TMS320C6416TBGLZ6?
The TMS320C6416TBGLZ6 is rated for extended temperature operation from −40°C to +105°C, making it suitable for deployment in outdoor cellular base stations and industrial telecom equipment where ambient conditions exceed commercial-grade limits. This rating is confirmed in the device characteristics table of SPRS226M and applies to the 'B' suffix variant. The TMS320C6416TBGLZ6 maintains full 1-GHz performance across this entire range when proper thermal management is implemented.
Does the TMS320C6416TBGLZ6 support PCI Express or only legacy PCI?
The TMS320C6416TBGLZ6 supports only PCI Specification 2.2 (32-bit/33-MHz), not PCI Express. Its PCI interface operates in both master and slave modes, with four-wire EEPROM configuration and programmable interrupt routing. No PCIe PHY, link training, or serial differential signaling capability exists on the TMS320C6416TBGLZ6 - migration to PCIe requires a different platform such as the C66x or Sitara AM57x families.
How does the VCP in the TMS320C6416TBGLZ6 differ from generic Viterbi accelerators?
The VCP in the TMS320C6416TBGLZ6 supports constraint lengths K = 5–9, code rates R = 1/2, 1/3, 1/4, and programmable polynomials - matching 3GPP AMR and GSM-EFR standards. It generates hard or soft decisions and operates at CPU clock ÷4, delivering >833 × 7.95-Kbps channels. Unlike fixed-function ASICs, the TMS320C6416TBGLZ6 VCP is configured via register writes and shares memory space with the CPU through EDMA, enabling dynamic reconfiguration per call setup.
Can the TMS320C6416TBGLZ6 boot directly from SPI flash memory?
No, the TMS320C6416TBGLZ6 does not support native SPI flash boot. Boot sources are limited to EMIF-connected parallel NOR/NAND flash, SDRAM, or host-loaded images via HPI or PCI. While a four-wire serial EEPROM interface exists for PCI configuration, it is not used for DSP bootloading. External boot ROM must be connected to EMIFA CE0 or CE1 with appropriate wait-state and timing configuration per the bootmode settings.
Is the TMS320C6416TBGLZ6 pin-compatible with the TMS320C6414T or TMS320C6415T?
Yes, the TMS320C6416TBGLZ6 is pin-for-pin compatible with the TMS320C6414T and TMS320C6415T under defined conditions: all three devices use identical 532-pin GLZ BGA packages, and compatibility holds when PCI and UTOPIA peripherals are disabled on the C6415T/C6416T, or when both devices operate in the same peripheral selection mode with BEA[9:7] pins correctly biased. Full compatibility requires adherence to the device configuration guidelines in Section 7 of SPRS226M.
