Texas Instruments TMS32C6415EGLZA5E0

Overview

TMS32C6415EGLZA5E0 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 2-ns instruction cycle time. It integrates dual external memory interfaces (64-bit EMIFA and 16-bit EMIFB), PCI 2.2 master/slave interface, UTOPIA Level 2 slave ATM controller, and three multichannel buffered serial ports (McBSPs) for telecom infrastructure applications.

For engineers reviewing the TMS32C6415EGLZA5E0 datasheet, TMS32C6415EGLZA5E0 pinout, TMS32C6415EGLZA5E0 application, or TMS32C6415EGLZA5E0 equivalent, key selection criteria include its 532-pin GLZ BGA package, 1.2-V core/3.3-V I/O voltage configuration, PCI and UTOPIA peripheral enablement, and compatibility with C6414/C6416 in shared-peripheral mode.

Technical Context

The TMS32C6415EGLZA5E0 implements an eight-functional-unit VelociTI.2™ DSP core with six ALUs and two multipliers-each multiplier supporting four 16×16-bit or eight 8×8-bit operations per cycle. Its L1/L2 memory hierarchy includes 16KB direct-mapped L1P cache, 16KB 2-way set-associative L1D cache, and 1024KB unified L2 RAM/cache with flexible allocation.

Peripheral integration includes a 32-bit/33-MHz PCI interface compliant with Specification 2.2, an 8-bit UTOPIA Level 2 slave controller operating up to 50 MHz per direction, and three McBSPs supporting T1/E1 framing, AC97, and SPI protocols. All peripherals are multiplexed with GPIO or HPI pins, requiring explicit device configuration via bootmode pins and BEA[9:7] strapping.

FAQ

What is the core voltage requirement for the TMS32C6415EGLZA5E0?

The TMS32C6415EGLZA5E0 requires a nominal 1.2-V core supply (VDD) with tight regulation (±3% tolerance) and low-noise filtering. This voltage powers the internal DSP core, L1 cache, and PLL circuitry. The 3.3-V I/O supply (VDDIO) is independent and must be sequenced after VDD reaches regulation to prevent latch-up. Power-supply sequencing is defined in Section 7.3 of SPRS146N.

Does the TMS32C6415EGLZA5E0 support PCI Express or only PCI 2.2?

The TMS32C6415EGLZA5E0 supports only PCI Specification 2.2 (32-bit/33-MHz), not PCI Express. Its PCI interface operates in both master and slave modes, with three address spaces (prefetchable memory, non-prefetchable memory, and I/O). It lacks PCIe-specific features such as serial lanes, link training, or advanced error reporting.

Can the TMS32C6415EGLZA5E0 execute C62x™ software without modification?

Yes-the TMS32C6415EGLZA5E0 is fully software-compatible with the TMS320C62x™ DSP family. Its instruction set extends C62x™ with VelociTI.2™ enhancements (e.g., quad 8-bit operations), but all C62x™ instructions execute identically. Legacy C62x™ code runs natively, though performance gains require recompilation with C64x™-optimized toolchain.

How many McBSPs does the TMS32C6415EGLZA5E0 include, and what protocols do they support?

The TMS32C6415EGLZA5E0 includes three multichannel buffered serial ports (McBSP0–McBSP2). Each supports T1/E1 framing, MVIP, SCSA, AC97, and SPI (Motorola™ format). They handle up to 256 channels each and operate with internal clocks derived from CPU/4, enabling synchronous audio and telecom data streaming without external clock generators.

Is the TMS32C6415EGLZA5E0 pin-compatible with the TMS320C6416GLZ7E3?

Yes-the TMS32C6415EGLZA5E0 and TMS320C6416GLZ7E3 share the same 532-pin GLZ BGA package and are pin-for-pin compatible when configured identically (i.e., disabling VCP/TCP-specific pins and matching BEA[9:7] strapping). However, differences in core voltage (1.2 V vs. 1.4 V) and thermal envelope require PCB-level power delivery and thermal redesign.
