Texas Instruments TMS320C6412AZNZ6

Overview

TMS320C6412AZNZ6 from Texas Instruments is a fixed-point digital signal processor (DSP) featuring a 600-MHz C64x+ CPU core, 1-MB on-chip L2 unified memory (SRAM/cache), and integrated peripherals including EMIF, EMAC, PCI, I²C, McBSP, HPI, and MDIO. It operates at 1.2-V core voltage and 3.3-V I/O, supporting real-time audio, telecom baseband, and industrial control applications requiring deterministic low-latency processing.

For engineers reviewing the TMS320C6412AZNZ6 datasheet, TMS320C6412AZNZ6 pinout, TMS320C6412AZNZ6 application, or TMS320C6412AZNZ6 equivalent, key selection criteria include its 600-MHz instruction throughput (4800 MIPS), BGA-361 ZNZ package with 0.8-mm pitch, EMAC/PCI dual-host interface capability, and support for SDRAM, asynchronous SRAM, and flash via EMIFA.

Technical Context

The TMS320C6412AZNZ6 implements the C64x+ VLIW architecture with eight parallel execution units (two multipliers, six ALUs), enabling single-cycle execution of up to eight instructions. Its memory subsystem includes 64 KB L1P program cache, 64 KB L1D data cache, and configurable 1-MB L2 memory partitioned as SRAM or cache.

Peripherals are tightly coupled via a 64-bit internal bus: the EMIF supports 16-/32-bit SDRAM, 8-/16-/32-bit asynchronous memory, and programmable synchronous interfaces; the EMAC provides 10/100 Mbps Ethernet MAC with MDIO management; and the PCI module complies with PCI Rev 2.2, supporting 33/66 MHz operation in target or host mode.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the TMS320C6412AZNZ6?

The TMS320C6412AZNZ6 is rated for a maximum CPU clock frequency of 600 MHz, delivering 4800 million instructions per second (MIPS). This rating is guaranteed under recommended operating conditions: core supply voltage of 1.20 V ± 0.03 V and case temperature range of 0°C to 90°C. The device achieves this speed using an internal PLL that multiplies a 12–50 MHz external CLKIN source, and the actual achievable frequency depends on board-level signal integrity and thermal management of the ZNZ BGA package.

Does the TMS320C6412AZNZ6 support Ethernet connectivity out of the box?

The TMS320C6412AZNZ6 integrates a fully compliant IEEE 802.3 10/100 Mbps Ethernet MAC (EMAC) with MDIO management interface, but it does not include a physical layer (PHY). To achieve functional Ethernet connectivity, an external 10/100BASE-TX PHY (e.g., DP83848) must be connected to the EMAC's MII signals (TXD/RXD, TX_EN, CRS, COL, etc.). The TMS320C6412AZNZ6 handles MAC-layer framing, checksum generation, and DMA-based packet buffering, reducing host CPU overhead compared to software-only implementations.

Can the TMS320C6412AZNZ6 boot from external flash memory?

Yes, the TMS320C6412AZNZ6 supports booting from external parallel NOR flash memory mapped through its EMIF. During reset, the device samples configuration pins (e.g., BOOTMODE[3:0]) to select boot mode; for flash boot, it initializes the EMIF, fetches the first 64 KB of code from flash address 0x00000000 into internal RAM, and begins execution. Supported flash types include 8-/16-/32-bit devices with common command sets (e.g., AMD/Fujitsu), and timing parameters (e.g., CE setup/hold, OE pulse width) must comply with Section 5 (Asynchronous Memory Timing) of the SPRS219J datasheet.

What is the function of the HPI interface on the TMS320C6412AZNZ6?

The Host-Port Interface (HPI) on the TMS320C6412AZNZ6 is a 16-bit parallel bus (HPI_HD[15:0], HPI_HCNTL[1:0], HPI_HDS1/HDS2, HPI_HR/W, HPI_HCS) that allows an external host processor (e.g., ARM or microcontroller) to directly read from and write to the TMS320C6412AZNZ6's internal memory map and peripheral registers. It is commonly used for firmware loading during startup, real-time debug monitoring, and runtime parameter updates - all without halting the DSP core, preserving deterministic signal processing behavior.

How does the TMS320C6412AZNZ6 manage power consumption in battery-operated systems?

The TMS320C6412AZNZ6 implements four hardware-controlled power-down modes (IDLE, STANDBY, HALT, DEEPSLEEP) accessible via the CSR register's PWRD field. In DEEPSLEEP mode, core clocks are gated, L1/L2 caches are flushed, and I/Os enter high-impedance state - reducing total current draw to ~1 mA. Wake-up is triggered by GPIO interrupts or external events (e.g., EMAC packet arrival), with typical resume latency under 10 µs. This enables energy-efficient operation in portable audio analyzers or wireless sensor gateways where active duty cycle is low.
