Product details
Overview
TMS32C6415EGLZ6E3 from Texas Instruments is a fixed-point digital signal processor (DSP) built on the VelociTI.2™ VLIW architecture, delivering 600-MHz clock rate, 4800 MIPS performance, and 1.67-ns instruction cycle time. It integrates dual external memory interfaces (64-bit EMIFA, 16-bit EMIFB), three multichannel buffered serial ports (McBSPs), and PCI 2.2 master/slave interface - enabling real-time baseband processing in wireless infrastructure equipment.
For engineers reviewing the TMS32C6415EGLZ6E3 datasheet, TMS32C6415EGLZ6E3 pinout, TMS32C6415EGLZ6E3 application, or TMS32C6415EGLZ6E3 equivalent, key selection criteria include its 532-pin GLZ BGA package, 3.3-V I/O / 1.4-V core voltage, UTOPIA Level 2 slave support, and pin-compatibility with TMS320C6414/C6416 for drop-in migration in telecom DSP subsystems.
Technical Context
The TMS32C6415EGLZ6E3 implements an eight-functional-unit VelociTI.2™ DSP core with six ALUs and two multipliers, supporting quad-8-bit and dual-16-bit arithmetic per cycle. Its L1/L2 memory hierarchy includes 16KB direct-mapped L1P cache, 16KB 2-way set-associative L1D cache, and 1024KB flexible L2 unified RAM/cache.
Peripheral integration includes EDMA with 64 independent channels, user-configurable 16-/32-bit HPI, three 32-bit timers, 16 GPIO pins, and multiplexed UTOPIA/PCI interfaces - all synchronized to CPU-derived clocks (e.g., McBSP at CPU/4, timers at CPU/8). The device operates under IEEE-1149.1 JTAG boundary-scan compliance for debug and test.

FAQ
What is the core voltage requirement for the TMS32C6415EGLZ6E3?
The TMS32C6415EGLZ6E3 requires a 1.4-V nominal core supply voltage, as specified for the -6E3 speed grade operating at 600 MHz. This voltage must be tightly regulated within ±3% tolerance to ensure stable operation of the VelociTI.2™ DSP core and prevent timing violations. The I/O banks operate at 3.3 V, and separate power domains require proper sequencing - core voltage must be established before I/O voltage during power-up. The TMS32C6415EGLZ6E3 datasheet defines absolute maximum ratings and recommended operating conditions for both supplies.
Does the TMS32C6415EGLZ6E3 support PCI Express or only legacy PCI?
The TMS32C6415EGLZ6E3 supports only PCI Specification 2.2 (32-bit/33-MHz), not PCI Express. Its PCI interface operates in master/slave mode with prefetchable/non-prefetchable memory and I/O address spaces, four-wire EEPROM interface, and programmable interrupt handling. PCI Express requires different physical layer signaling, transaction layer protocols, and link training - none of which are implemented in the TMS32C6415EGLZ6E3. For PCIe-based systems, designers must use an external bridge or select a newer-generation DSP or SoC. The TMS32C6415EGLZ6E3 remains fully compatible with legacy PCI add-in cards and motherboards.
Can the TMS32C6415EGLZ6E3 execute C62x™-compiled code without modification?
Yes, the TMS32C6415EGLZ6E3 is fully software-compatible with the TMS320C62x™ DSP family at the assembly language level. Its VelociTI.2™ instruction set extends the C62x™ base while maintaining backward compatibility - all C62x™ instructions execute identically, and new C64x™-specific instructions (e.g., quad-8-bit operations) are ignored by C62x™ code. Texas Instruments confirms this in SPRS146N: "Fully Software-Compatible With C62x™". However, optimal performance requires recompilation with the C64x™-optimized C compiler to exploit enhanced parallelism and memory bandwidth. Legacy C62x™ binaries run on the TMS32C6415EGLZ6E3 but do not utilize its full 4800-MIPS capability.
How does the UTOPIA interface on the TMS32C6415EGLZ6E3 differ from that on the TMS320C6416?
The UTOPIA interface on the TMS32C6415EGLZ6E3 is identical in specification to that on the TMS320C6416: both implement UTOPIA Level 2 slave mode with 8-bit transmit/receive paths, 50-MHz maximum clock rate per direction, and user-defined cell formats up to 64 bytes. No functional or timing differences exist between the two devices' UTOPIA blocks - they share the same register map, interrupt behavior, and electrical characteristics. The distinction lies solely in device-level peripheral allocation: the TMS320C6416 omits UTOPIA when VCP/TCP coprocessors are enabled, whereas the TMS32C6415EGLZ6E3 dedicates dedicated pins to UTOPIA regardless of other peripheral configurations. This makes the TMS32C6415EGLZ6E3 more predictable for ATM-based designs.
Is the TMS32C6415EGLZ6E3 pin-compatible with the TMS320C6414 and TMS320C6416?
Yes, the TMS32C6415EGLZ6E3 is pin-for-pin compatible with the TMS320C6414 and TMS320C6416 when using identical peripheral configurations. All three devices use the same 532-pin GLZ BGA package and share identical pin functions for EMIFA, EMIFB, McBSPs, timers, GPIO, and JTAG. PCI and UTOPIA pins are multiplexed with HPI and McBSP1 respectively - so compatibility requires disabling those peripherals on the C6414 or ensuring matching selection modes on the C6416. Texas Instruments explicitly states in SPRS146N: "C6414/15/16 Devices Pin-Compatible" and provides BEA[9:7] pin-strapping guidance to enforce consistent peripheral mapping. PCBs designed for one can accommodate the others with only firmware and configuration changes.
