Texas Instruments 66AK2H06BAAWA24

Overview

66AK2H06BAAWA24 from Texas Instruments is a multicore DSP+ARM System-on-Chip (SoC) integrating four ARM Cortex-A15 cores at up to 1.4 GHz and four TMS320C66x DSP cores at up to 1.2 GHz, with 6 MB shared MSMC SRAM, dual 72-bit DDR3/DDR3L interfaces (1600 MHz), and a 5-port Gigabit Ethernet switch - deployed in media processing, wireless infrastructure baseband, and secure packet inspection systems.

For engineers reviewing the 66AK2H06BAAWA24 datasheet, 66AK2H06BAAWA24 pinout, 66AK2H06BAAWA24 application, or 66AK2H06BAAWA24 equivalent, key selection criteria include confirmed 4×C66x + 2×A15 core count, 14×64-bit timers, AAW 1517-pin flip-chip BGA package, and absence of 10-GbE XFI support compared to 66AK2H14.

Technical Context

The 66AK2H06BAAWA24 implements KeyStone II architecture with discrete ARM and DSP subsystems sharing coherent memory via MSMC and Multicore Navigator. Its ARM CorePac delivers full ARMv7-A compliance with ACE master port to MSMC, while each C66x CorePac includes 32-KB L1P, 32-KB L1D, and 1024-KB local L2 cache.

Hardware acceleration is distributed across dedicated blocks: Network Coprocessor handles packet acceleration (IPsec, GTP-U, PDCP) and security acceleration (AES, SHA-2, Kasumi), while EDMA3 modules enable zero-overhead data movement between peripherals and memory spaces without CPU intervention.

Key Specifications

Pinout & Package

66AK2H06BAAWA24 uses the AAW package: 1517-pin flip-chip plastic BGA, 40.0 mm × 40.0 mm body size, 0.8 mm ball pitch. Pin functions are defined per TI SPRS866G Rev G, with reserved XFI pins (for 10-GbE) unconnected in this variant.

FAQ

What is the maximum operating frequency of the ARM and DSP cores in the 66AK2H06BAAWA24?

The 66AK2H06BAAWA24 integrates two ARM Cortex-A15 cores and four TMS320C66x DSP cores, each capable of operating at up to 1.4 GHz (ARM) and 1.2 GHz (DSP) respectively, as specified in the SPRS866G datasheet Revision G. These frequencies are achievable under recommended operating conditions including proper thermal management and voltage regulation. The 66AK2H06BAAWA24 achieves 38.4 GMACS/core and 19.2 GFLOPS/core on the C66x DSPs at 1.2 GHz.

Does the 66AK2H06BAAWA24 support 10-Gigabit Ethernet?

No, the 66AK2H06BAAWA24 does not support 10-Gigabit Ethernet. Its Ethernet subsystem consists of a five-port Gigabit Ethernet switch with SGMII interfaces only. The 10-GbE XFI functionality is exclusive to the 66AK2H14 variant and is implemented using reserved pins on the AAW package that remain unconnected and unused in the 66AK2H06BAAWA24.

How many 64-bit timers does the 66AK2H06BAAWA24 include, and how are they allocated?

The 66AK2H06BAAWA24 includes fourteen 64-bit configurable timers, as confirmed in Table 3-1 of SPRS866G. These timers are globally accessible and can be assigned to either ARM or DSP subsystems via the interrupt controller and timer configuration registers. They support free-running, periodic, and watchdog modes, and are used for real-time task scheduling, hardware synchronization, and timestamping in applications such as IEEE 1588 PTP.

What package type and pin count does the 66AK2H06BAAWA24 use?

The 66AK2H06BAAWA24 uses the AAW package: a 1517-pin flip-chip plastic BGA with 40.0 mm × 40.0 mm body size and 0.8 mm ball pitch. This package is shared across the 66AK2Hxx family and supports thermal dissipation requirements up to 12 W typical. Pin assignments are documented in Section 4 of SPRS866G, with XFI-related balls reserved and non-functional in this variant.

Is the 66AK2H06BAAWA24 supported by TI's Processor SDK and Code Generation Tools?

Yes, the 66AK2H06BAAWA24 is fully supported by Texas Instruments' Processor SDK RTOS and Linux editions, including drivers for DDR3, EMIF, EDMA3, PCIe, SRIO, and the Network Coprocessor. TI's C6000 Code Generation Tools v8.3.x and ARM compiler toolchains integrate with CCS v10+ for joint ARM/DSP development. Reference examples for packet acceleration and heterogeneous task partitioning are provided in the SDK for the 66AK2H06BAAWA24.
