Texas Instruments TMS320C6672ACYP

Overview

TMS320C6672ACYP from Texas Instruments is a dual-core fixed- and floating-point digital signal processor based on the KeyStone multicore architecture, featuring two 1.5 GHz C66x DSP cores delivering 48 GMAC/core and 24 GFLOP/core, 1 MB L2 cache per core, 4 MB shared MSM SRAM, and integrated network coprocessor with packet and security acceleration - deployed in high-throughput wireless baseband and media infrastructure systems.

For engineers reviewing the TMS320C6672ACYP datasheet, TMS320C6672ACYP pinout, TMS320C6672ACYP application, or TMS320C6672ACYP equivalent, key selection criteria include dual-C66x core performance at 1.5 GHz, hardware-accelerated packet processing up to 1.5 Mpps, DDR3-1600 interface with ECC support, and HyperLink interconnect for chip-to-chip scalability in telecom and radar systems.

Technical Context

The TMS320C6672ACYP implements TI's KeyStone architecture with four foundational elements: Multicore Navigator (8192 hardware queues), TeraNet non-blocking switch fabric, Multicore Shared Memory Controller (MSMC) for direct access to 4 MB shared SRAM and DDR3-1600 EMIF, and HyperLink (50 Gbaud full-duplex) for seamless multi-chip resource pooling.

Its dual C66x CorePacs each integrate 32 KB L1P, 32 KB L1D, and 512 KB configurable L2 memory with error correction; the Network Coprocessor includes dedicated Packet Accelerator (L2–L4 classification, checksum, QoS) and Security Accelerator (AES, SHA-2, GCM, up to 2.8 Gbps encryption), both operating independently of CPU cores.

Key Specifications

Pinout & Package

The TMS320C6672ACYP is housed in an 841-pin FC-BGA package (19 mm × 19 mm, 0.8 mm pitch) with thermal lid, designed for high-density PCB layouts in telecom and defense applications requiring controlled impedance routing and thermal management.

Equivalent & Alternatives

The following parts are listed as comparable options for similar multicore DSP applications.

Compared with TMS320C6672ACYP, the TMS320C6678ACYA offers scalable compute and interconnect for larger systems but requires mechanical redesign, while the ADSP-SC589KSWZ-4 trades packet acceleration and HyperLink for ARM+SHARC flexibility in non-telecom domains - neither is pin-compatible, and selection depends on whether system-level throughput or architectural alignment dominates the design priority.

FAQ

What is the maximum operating frequency of the TMS320C6672ACYP cores?

The TMS320C6672ACYP features two C66x DSP cores rated for operation up to 1.5 GHz. At this frequency, each core delivers 48 GMAC (fixed-point) and 24 GFLOP (floating-point) performance. The device supports lower speed grades (1.0 GHz and 1.25 GHz) depending on configuration and thermal conditions, but the TMS320C6672ACYP variant is specified for 1.5 GHz operation under extended temperature conditions (–40°C to +100°C).

Does the TMS320C6672ACYP support DDR3 memory with error correction?

Yes, the TMS320C6672ACYP includes a 64-bit DDR3-1600 external memory interface with full ECC (Error Correction Code) support for DRAM. This enables single-bit error correction and double-bit error detection, enhancing system reliability in mission-critical applications such as wireless baseband and radar. The DDR3 controller also supports programmable timing parameters and on-die termination calibration.

How does the Network Coprocessor in the TMS320C6672ACYP reduce CPU load?

The Network Coprocessor in the TMS320C6672ACYP consists of two independent engines - Packet Accelerator and Security Accelerator - that operate autonomously from the C66x cores. It handles L2–L4 packet classification, checksum insertion/verification, QoS tagging, IPsec encryption/decryption, and TLS handshake offload, freeing both DSP cores to focus exclusively on signal processing tasks without context switching or interrupt overhead.

Is the TMS320C6672ACYP pin-compatible with other C66x-based devices like the TMS320C6678?

No, the TMS320C6672ACYP is not pin-compatible with the TMS320C6678 or other members of the C66x family. It uses an 841-pin FC-BGA package, whereas the TMS320C6678 employs a 900-pin package with different pin assignments, power delivery requirements, and thermal pad layout. Migration between these devices requires PCB redesign and signal integrity revalidation.

What development tools are supported for the TMS320C6672ACYP?

Texas Instruments provides full toolchain support for the TMS320C6672ACYP, including the C6000 Code Generation Tools (C compiler, assembler, linker), Code Composer Studio IDE (v6.x+), DSP/BIOS and SYS/BIOS real-time kernels, and the Multicore Software Development Kit (MCSDK) with pre-validated drivers for SRIO, PCIe, HyperLink, and the Network Coprocessor. Evaluation is enabled via the TMS320C6678 EVM, which shares compatible software infrastructure despite hardware differences.
