Texas Instruments TMS320C6415TBCLZ7

Overview

TMS320C6415TBCLZ7 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 and 16-bit EMIFB), and targets wireless infrastructure baseband processing.

For engineers reviewing the TMS320C6415TBCLZ7 datasheet, TMS320C6415TBCLZ7 pinout, TMS320C6415TBCLZ7 application, or TMS320C6415TBCLZ7 equivalent, key selection criteria include its 720-MHz fixed-point DSP core, PCI 2.2 interface support, UTOPIA Level 2 slave ATM controller, three McBSPs for T1/E1 framing, and 532-pin CLZ BGA package with 0.8-mm pitch.

Technical Context

The TMS320C6415TBCLZ7 implements an advanced 8-unit VelociTI.2™ VLIW core: six ALUs (supporting quad 8-bit, dual 16-bit, or single 32-bit ops/cycle) and two multipliers (four 16×16-bit or eight 8×8-bit multiplies/cycle). Its non-aligned load-store architecture enables byte-, half-word-, word-, and doubleword-addressable memory access with full conditional execution.

Memory hierarchy includes direct-mapped 128K-bit L1P, 2-way set-associative 128K-bit L1D, and flexible 8M-bit L2 configurable as mapped RAM or mixed cache/RAM. Peripherals include EDMA (64 channels), HPI (16/32-bit configurable), three 32-bit timers, 16 GPIO pins, and multiplexed UTOPIA/PCI interfaces - all operating at 3.3-V I/O with 1.2-V core supply.

FAQ

What is the maximum operating frequency of the TMS320C6415TBCLZ7?

The TMS320C6415TBCLZ7 operates at a maximum clock rate of 720 MHz, corresponding to a 1.39-ns instruction cycle time. This frequency is achieved with a 1.2-V core supply and validated across commercial temperature range (0°C to 90°C case temperature). The device uses an internal PLL with selectable multipliers (x6, x12, x20) to generate this clock from a low-frequency external source, and timing specifications in SPRS226M Section 7 confirm AC performance compliance at this speed.

Does the TMS320C6415TBCLZ7 support PCI interface functionality?

Yes, the TMS320C6415TBCLZ7 includes a 32-bit PCI 2.2-compliant master/slave interface, as confirmed in SPRS226M Table 2 and Section 5. It supports prefetchable/non-prefetchable memory and I/O address spaces, four-wire EEPROM configuration, and programmable interrupt generation. The PCI interface shares pins with HPI and GPIO[15:9], requiring proper multiplexing configuration during boot - detailed in the Device Configurations section of the datasheet.

What memory resources are integrated into the TMS320C6415TBCLZ7?

The TMS320C6415TBCLZ7 integrates 16KB L1P direct-mapped program cache, 16KB L1D 2-way set-associative data cache, and 1024KB unified L2 memory that can be flexibly allocated as mapped RAM or cache (up to 256KB cache). Total on-chip memory capacity is 1056KB. External memory is accessed via EMIFA (64-bit) and EMIFB (16-bit), supporting up to 1280MB address space including SDRAM, ZBT SRAM, and asynchronous devices.

Is the TMS320C6415TBCLZ7 pin-compatible with other C64xT devices?

Yes, the TMS320C6415TBCLZ7 is pin-for-pin compatible with TMS320C6414TBGLZ7 and TMS320C6416TBCLZ7 when using identical peripheral configurations. SPRS226M Section 7 explicitly states compatibility under conditions: disabling PCI/UTOPIA on C6415T/C6416T when interfacing with C6414T, and ensuring BEA[9:7] pins are correctly terminated. All three share the 532-pin CLZ BGA package and identical signal mapping for EMIF, McBSP, timer, and GPIO functions.

What development tools are supported for the TMS320C6415TBCLZ7?

Texas Instruments provides full toolchain support for the TMS320C6415TBCLZ7, including the C6000 Code Generation Tools (C compiler, assembler, linker), Code Composer Studio™ IDE v3.3+ with real-time analysis, and the TMS320C64x DSP Starter Kit (DSK) for hardware evaluation. Debugging leverages IEEE-1149.1 JTAG via EMU0–EMU3 pins, and TI's DSP/BIOS real-time kernel enables deterministic thread scheduling for multi-tasking signal processing applications.
