Texas Instruments TMS320C6416TBZLZA7

Overview

TMS320C6416TBZLZA7 from Texas Instruments is a 1-GHz fixed-point digital signal processor (DSP) with VelociTI.2™ VLIW architecture, eight functional units, 64 × 32-bit registers, and dual on-chip coprocessors (VCP and TCP) for real-time channel decoding. It delivers 8000 MIPS and 8000 MMACS, targeting wireless infrastructure baseband processing where deterministic low-latency execution and high-throughput data path acceleration are required.

For engineers reviewing the TMS320C6416TBZLZA7 datasheet, TMS320C6416TBZLZA7 pinout, TMS320C6416TBZLZA7 application, or TMS320C6416TBZLZA7 equivalent, key selection criteria include its 1-GHz clock rate, 532-pin BGA package (ZLZ), integrated VCP/TCP for AMR/3GPP turbo decoding, dual EMIFs (64-bit EMIFA + 16-bit EMIFB), and PCI 2.2 interface support - all critical for telecom hardware design, real-time DSP firmware development, and migration from C62x/C64x legacy platforms.

Technical Context

The TMS320C6416TBZLZA7 implements a two-side CPU core with independent A/B register files and data cross paths, enabling simultaneous access to both 32-register banks per execute packet. Its VelociTI.2™ extensions support quad-8-bit and dual-16-bit packed arithmetic, non-aligned load/store, and conditional execution across all 64 registers.

This device integrates application-specific hardware including a Viterbi Decoder Coprocessor (VCP) operating at CPU/4 (250 MHz) supporting >833 AMR 7.95-Kbps channels, and a Turbo Decoder Coprocessor (TCP) at CPU/2 (500 MHz) handling up to 10 × 2-Mbps or 60 × 384-Kbps 3GPP frames with programmable iterations and interleaver parameters - both interfaced via EDMA without CPU intervention.

FAQ

What is the maximum operating frequency of the TMS320C6416TBZLZA7?

The TMS320C6416TBZLZA7 operates at a maximum clock rate of 1 GHz, achieving 8000 million instructions per second (MIPS) and 8000 million multiply-accumulates per second (MMACS). This frequency is sustained under recommended operating conditions: 1.2-V core voltage, 3.3-V I/O voltage, and case temperature ≤ 85°C. The device uses an internal PLL with ×20 multiplier fed by a 50-MHz CLKIN source to reach this speed.

Does the TMS320C6416TBZLZA7 include hardware accelerators for telecom channel decoding?

Yes, the TMS320C6416TBZLZA7 integrates two dedicated coprocessors: the Viterbi Decoder Coprocessor (VCP) and Turbo Decoder Coprocessor (TCP). The VCP supports >833 AMR 7.95-Kbps voice channels at CPU/4 clock speed, while the TCP handles up to 10 × 2-Mbps or 60 × 384-Kbps 3GPP turbo frames at CPU/2 - both accessible via EDMA and fully programmable for constraint length, code rate, and iteration count.

What package type and pin count does the TMS320C6416TBZLZA7 use?

The TMS320C6416TBZLZA7 uses a 532-pin Ball Grid Array (BGA) package with ZLZ suffix, measuring 23 mm × 23 mm with 0.8-mm ball pitch. It is fabricated using 0.09-µm CMOS technology and features 3.3-V I/Os and 1.2-V internal core voltage. Pin compatibility is confirmed with C6414T/C6415T devices when PCI and UTOPIA peripherals are disabled.

Which external memory interfaces are supported by the TMS320C6416TBZLZA7?

The TMS320C6416TBZLZA7 supports two glueless external memory interfaces: a 64-bit EMIFA for high-bandwidth connections to SDRAM, ZBT SRAM, and FIFOs, and a 16-bit EMIFB for lower-speed peripherals like flash or FPGA configuration memory. Together they provide up to 1280 MB of total addressable external memory space, with configurable wait-state and burst-length timing parameters.

Is the TMS320C6416TBZLZA7 pin-compatible with other C64xT devices?

Yes, the TMS320C6416TBZLZA7 is pin-for-pin compatible with the TMS320C6414T and TMS320C6415T when configured identically - specifically, with PCI and UTOPIA peripherals disabled on the C6415T/C6416T. Compatibility requires proper BEA[9:7] pin strapping and adherence to shared peripheral selection modes defined in the Device Configurations section of the datasheet.
