Product details
Overview
TMS320C6415TBZLZ7 from Texas Instruments is a high-performance fixed-point digital signal processor (DSP) based on the VelociTI.2™ VLIW architecture, delivering 720 MHz clock rate (1.39-ns cycle), 5760 MIPS, and eight 32-bit instructions per cycle. It integrates 16KB L1P cache, 16KB L1D cache, and 1024KB unified L2 RAM/cache, with dual external memory interfaces (64-bit EMIFA + 16-bit EMIFB) for wireless infrastructure baseband processing.
For engineers reviewing the TMS320C6415TBZLZ7 datasheet, TMS320C6415TBZLZ7 pinout, TMS320C6415TBZLZ7 application, or TMS320C6415TBZLZ7 equivalent, this page provides verified functional unit configuration, PCI/UTOPIA peripheral availability, EMIF timing constraints, and pin-compatible migration paths within the C6414T/C6415T/C6416T family.
Technical Context
The TMS320C6415TBZLZ7 implements a dual-data-path CPU with two register files (A/B, 64 × 32-bit registers), six ALUs (supporting quad-8-bit/dual-16-bit/32-bit arithmetic), and two multipliers enabling four 16×16-bit MACs/cycle (4000 MMACS) or eight 8×8-bit MACs/cycle (8000 MMACS). Its non-aligned load-store architecture supports byte/half-word/word/doubleword addressing with full conditional execution.
It features a flexible two-level memory hierarchy: direct-mapped 16KB L1P, 2-way set-associative 16KB L1D, and configurable 1024KB L2 supporting mixed mapped RAM/cache allocation. Peripherals include three McBSPs (256-channel TDM support), 32-bit timers, 16-pin GPIO, user-configurable HPI (16/32-bit), and - critically for this variant - PCI v2.2 master/slave interface and UTOPIA Level 2 slave ATM controller (8-bit, up to 50 MHz/direction).
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-point DSP applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320C6415TBCZ7 | Same core, CLZ package (0.8-mm pitch, 23×23 mm), but commercial temperature range (0°C to 90°C) vs. extended −40°C to 105°C. | Lacks extended temperature qualification; unsuitable for outdoor base station cabinets or industrial enclosures. | Select when operating environment stays within 0°C–90°C and PCB layout accommodates identical footprint. |
| TMS320C6416TBZLZ7 | Adds VCP/TCP coprocessors for AMR/turbo decoding; otherwise pin-, software-, and package-compatible. | Enables integrated channel decoding in 3GPP-compliant systems; adds ~150 mW static power at 720 MHz. | Choose when Viterbi/Turbo acceleration is required; no PCB changes needed if UTOPIA/PCI pins are unused. |
Compared with TMS320C6415TBZLZ7, the TMS320C6415TBCZ7 offers identical performance in commercial environments but lacks extended temperature support, while the TMS320C6416TBZLZ7 adds hardware-accelerated channel decoding at minor power cost - making it superior for 3G baseband where decoding latency must be sub-100 µs.

FAQ
What is the maximum supported clock frequency for the TMS320C6415TBZLZ7?
The TMS320C6415TBZLZ7 operates at a guaranteed maximum clock frequency of 720 MHz, corresponding to a 1.39-ns instruction cycle time per TI SPRS226M revision April 2009. This rating applies under extended temperature conditions (−40°C to 105°C) with 1.2-V core supply and proper decoupling. Higher frequencies (850 MHz/1 GHz) require different speed grades (e.g., -850/-1G suffixes) and are not valid for this specific part number.
Does the TMS320C6415TBZLZ7 include Viterbi or Turbo decoder coprocessors?
No, the TMS320C6415TBZLZ7 does not integrate VCP or TCP coprocessors. These accelerators are exclusive to the TMS320C6416T device family per TI SPRS226M Table 2 and Section 5. The TMS320C6415TBZLZ7 shares the same C64x™ core and peripheral set as the C6416T except for the absence of VCP/TCP hardware - all other features including PCI, UTOPIA, McBSPs, and EMIFs remain fully functional.
Which external memory types are supported by the TMS320C6415TBZLZ7 EMIFs?
The TMS320C6415TBZLZ7 supports asynchronous memories (SRAM, EPROM) and synchronous memories (SDRAM, SBSRAM, ZBT SRAM, FIFO) via its 64-bit EMIFA and 16-bit EMIFB interfaces. Glueless operation is confirmed for 133-MHz SDRAM and 200-MHz ZBT SRAM per TI timing tables SPRS226M Sections 8–10. Asynchronous interface timings accommodate 10-ns SRAM access with appropriate WAIT-state configuration.
Is the TMS320C6415TBZLZ7 pin-compatible with the TMS320C6414T or TMS320C6416T?
Yes, the TMS320C6415TBZLZ7 is pin-for-pin compatible with both TMS320C6414T and TMS320C6416T when using identical peripheral configurations. Per TI SPRS226M Section 7, compatibility requires disabling PCI and UTOPIA on C6415T/C6416T if those peripherals are unused on the C6414T design, and correct BEA[9:7] pin strapping. All three share the same 532-pin ZLZ/GLZ/CLZ BGA package and ball map.
What development tools are officially supported for the TMS320C6415TBZLZ7?
Texas Instruments officially supports the C64x™ Code Generation Tools suite for the TMS320C6415TBZLZ7, including the C6000™ C/C++ compiler (v7.4+), assembly optimizer, and Code Composer Studio™ v3.3/v4.x IDE with XDS560-class JTAG emulators. TI's C64x™ DSP/BIOS real-time kernel and Chip Support Library (CSL) provide validated drivers for McBSP, EMIF, HPI, and timer peripherals.
