Texas Instruments TMS32C6415EGLZA6E3

Overview

TMS32C6415EGLZA6E3 from Texas Instruments is a high-performance fixed-point digital signal processor (DSP) based on the VelociTI.2™ VLIW architecture, operating at 600 MHz with 1.67-ns instruction cycle time, delivering 4800 MIPS and supporting eight 32-bit instructions per cycle. It integrates dual external memory interfaces (64-bit EMIFA, 16-bit EMIFB), three multichannel buffered serial ports (McBSPs), and a 32-bit/33-MHz PCI interface - deployed in telecom infrastructure for real-time voice and data channel processing.

For engineers reviewing the TMS32C6415EGLZA6E3 datasheet, TMS32C6415EGLZA6E3 pinout, TMS32C6415EGLZA6E3 application, or TMS32C6415EGLZA6E3 equivalent, key selection criteria include its 600-MHz CPU clock, 1.4-V core voltage, 532-pin GLZ BGA package, PCI v2.2 compliance, and UTOPIA Level 2 slave support - all critical for legacy telecom baseband and ATM edge node designs requiring deterministic fixed-point throughput.

Technical Context

The TMS32C6415EGLZA6E3 implements an advanced eight-functional-unit VelociTI.2™ DSP core with six ALUs (supporting quad 8-bit, dual 16-bit, or single 32-bit arithmetic per cycle) and two multipliers (enabling four 16×16-bit or eight 8×8-bit MACs/cycle). Its non-aligned load-store architecture and 64 general-purpose 32-bit registers enable efficient packed-data processing for voice codecs and channel equalization.

It features a hierarchical L1/L2 memory system: 16KB direct-mapped L1P program cache, 16KB 2-way set-associative L1D data cache, and 1024KB unified L2 RAM/cache configurable as mapped memory or cache. Peripheral integration includes EDMA (64 channels), HPI (16-/32-bit configurable), three 32-bit timers, and GPIO (16 pins), all synchronized to CPU-derived clocks.

FAQ

What is the core voltage requirement for the TMS32C6415EGLZA6E3?

The TMS32C6415EGLZA6E3 requires a 1.4-V nominal core supply (VDD) for operation at 600 MHz, as specified in the recommended operating conditions table of the SPRS146N datasheet. This voltage must be tightly regulated with ±3% tolerance and low noise (<10 mVpp) to ensure stable CPU execution and prevent timing violations in the 1.67-ns cycle.

Does the TMS32C6415EGLZA6E3 support PCI bus mastering?

Yes, the TMS32C6415EGLZA6E3 implements a full 32-bit/33-MHz PCI v2.2 interface with master and slave capability. It supports prefetchable memory, non-prefetchable memory, and I/O address spaces via three programmable PCI BARs, enabling direct memory access to host system resources without CPU intervention.

Is the TMS32C6415EGLZA6E3 pin-compatible with the TMS320C6416GLZ7E3?

Yes - the TMS32C6415EGLZA6E3 and TMS320C6416GLZ7E3 share the identical 532-pin GLZ BGA package and pinout. They are pin-for-pin compatible when UTOPIA and PCI peripherals are enabled on both devices, as confirmed in the device compatibility section of SPRS146N.

What memory types can be interfaced using the EMIFA on the TMS32C6415EGLZA6E3?

The 64-bit EMIFA on the TMS32C6415EGLZA6E3 supports glueless interfacing to asynchronous memories (SRAM, EPROM) and synchronous memories including SDRAM, SBSRAM, ZBT SRAM, and FIFOs. Its programmable timing registers allow configuration for JEDEC-compliant SDRAM burst modes and CAS latency settings.

How many McBSPs does the TMS32C6415EGLZA6E3 include, and what protocols do they support?

The TMS32C6415EGLZA6E3 integrates three multichannel buffered serial ports (McBSP0–McBSP2), each supporting T1/E1 framing, MVIP, SCSA, AC97, and SPI protocols. Each McBSP handles up to 256 channels and operates at CPU/4 clock frequency, enabling simultaneous connection to multiple audio codecs and telecom framer ICs.
