For engineers reviewing the TMS320C6415TGLZ7 datasheet, TMS320C6415TGLZ7 pinout, TMS320C6415TGLZ7 application, or TMS320C6415TGLZ7 equivalent, key selection criteria include its 720-MHz real-time processing capability, PCI 2.2 master/slave interface, UTOPIA Level 2 slave ATM controller, three McBSPs for T1/E1 framing, and 532-pin GLZ BGA package compatibility with C6414T/C6416T under shared peripheral configuration.

Technical Context

The TMS320C6415TGLZ7 implements an advanced 8-unit VelociTI.2™ DSP core with six ALUs (32-/40-bit) and two multipliers-each supporting four 16×16-bit or eight 8×8-bit multiplies per cycle-and features non-aligned load-store architecture with 64 general-purpose 32-bit registers. Its memory subsystem includes direct-mapped L1P, 2-way set-associative L1D, and flexible 8-Mbit L2 configurable as mapped RAM or cache.

Peripherals include three multichannel buffered serial ports (McBSPs), a user-configurable 16/32-bit HPI, 32-bit/33-MHz PCI 2.2 interface, 8-bit UTOPIA Level 2 slave ATM controller (up to 50 MHz per direction), three 32-bit timers, 16 GPIO pins, and a flexible PLL supporting CLKIN ×1, ×6, ×12, or ×20 multiplication-enabling precise clock domain management in telecom timing-critical systems.

FAQ

What is the maximum operating frequency of the TMS320C6415TGLZ7?

The TMS320C6415TGLZ7 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 is validated across commercial temperature ranges per TI SPRS226M datasheet Section 6. The device also supports lower-speed variants (600/850/1000 MHz), but the GLZ7 suffix specifically denotes the 720-MHz grade of the TMS320C6415TGLZ7.

Does the TMS320C6415TGLZ7 support PCI interface functionality?

Yes, the TMS320C6415TGLZ7 includes a fully compliant 32-bit/33-MHz PCI 2.2 master/slave interface, accessible via pins PCI_AD[31:0], PCI_CBE[3:0], and PCI_FRAME. It supports prefetchable/non-prefetchable memory and I/O address spaces, and allows DSP-initiated bus transactions or interrupt assertion under program control-enabling direct integration into PCI-based carrier-grade hardware platforms.

How does the UTOPIA interface on the TMS320C6415TGLZ7 differ from the C6414T variant?

The TMS320C6415TGLZ7 integrates an 8-bit UTOPIA Level 2 slave ATM controller operating up to 50 MHz per direction, while the TMS320C6414T lacks UTOPIA entirely. This interface shares pins with McBSP1 and requires explicit configuration via the PERCFG register. Its presence enables direct cell-level transport in DSLAMs and MSANs-differentiating TMS320C6415TGLZ7 from C6414T in ATM-centric applications.

What memory architecture does the TMS320C6415TGLZ7 use, and how is L2 allocated?

The TMS320C6415TGLZ7 uses a two-level cache-based memory architecture: 16KB L1P (direct-mapped), 16KB L1D (2-way set-associative), and 1024KB unified L2. The L2 space is flexibly partitionable between mapped RAM and cache (up to 256KB cache); default configuration allocates all 1024KB as mapped RAM unless explicitly configured otherwise via L2CFG register-supporting large real-time buffers or coefficient tables.

Is the TMS320C6415TGLZ7 pin-compatible with other C64xT devices?

Yes, the TMS320C6415TGLZ7 is pin-for-pin compatible with TMS320C6414T and TMS320C6416T in the GLZ package, provided peripheral selection aligns: PCI and UTOPIA must be disabled on C6414T to match TMS320C6415TGLZ7 pin usage, and BEA[9:7] pins must be correctly terminated per datasheet Table 2. This compatibility simplifies migration and multi-variant board design.
