Texas Instruments 66AK2H06DXAAW2

Overview

66AK2H06DXAAW2 from Texas Instruments is a KeyStone II–based multicore SoC integrating two ARM Cortex-A15 processors (up to 1.4 GHz) and four TMS320C66x DSP cores (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. It targets media processing, analytics, and embedded infrastructure where heterogeneous compute and packet acceleration are required.

For engineers reviewing the 66AK2H06DXAAW2 datasheet, 66AK2H06DXAAW2 pinout, 66AK2H06DXAAW2 application, or 66AK2H06DXAAW2 equivalent, key selection considerations include its 4-C66x + 2-A15 core configuration, 14 × 64-bit timers, SmartReflex™ voltage scaling, and AAW 1517-pin flip-chip BGA package for thermal and signal integrity in high-throughput systems.

Technical Context

The 66AK2H06DXAAW2 implements a tightly coupled heterogenous architecture: ARM cores handle OS, control, and protocol stack execution while C66x DSPs perform real-time signal, video, and packet processing. Its Multicore Navigator provides 16k hardware queues and zero-overhead packet DMA, enabling deterministic data movement across eight memory domains.

On-chip accelerators include a Network Coprocessor with Packet Accelerator (supporting GTP-U, SCTP, PDCP, RoHC) and Security Accelerator (AES, SHA-2, HMAC, Kasumi, SNOW 3G) delivering up to 2.4 Gbps IPSec and 2.4 Gbps air ciphering. The device uses five independent PLLs for domain-specific clock generation and supports IEEE 1588 time synchronization via dedicated hardware.

FAQ

What is the maximum operating frequency of the ARM and DSP cores in the 66AK2H06DXAAW2?

The 66AK2H06DXAAW2 features two ARM Cortex-A15 processors operating up to 1.4 GHz and four TMS320C66x DSP cores operating up to 1.2 GHz. These frequencies are guaranteed under recommended operating conditions including junction temperature ≤ 100°C and proper power rail sequencing. The 66AK2H06DXAAW2 achieves 38.4 GMACS/core and 19.2 GFLOPS/core at 1.2 GHz for fixed- and floating-point workloads respectively.

Does the 66AK2H06DXAAW2 support DDR3L memory?

Yes, the 66AK2H06DXAAW2 supports both DDR3 and DDR3L memory through its dual 72-bit EMIF interfaces, with operation up to 1600 MHz. The DDR3L compatibility is explicitly confirmed in Revision G of the SPRS866G datasheet, which updated DVDD15 power supply specifications to 1.35/1.5 V to accommodate DDR3L VDDQ requirements. This allows lower-power memory subsystem design without sacrificing bandwidth.

How many 64-bit timers does the 66AK2H06DXAAW2 include, and what are their primary use cases?

The 66AK2H06DXAAW2 integrates fourteen 64-bit configurable timers, as specified in Table 3-1 of the SPRS866G datasheet. These timers support free-running, periodic, and one-shot modes with programmable prescalers and interrupt generation. They are commonly used for real-time task scheduling, timestamping of network packets in the 5-port Ethernet switch, synchronization of sensor sampling in industrial analytics, and watchdog supervision across heterogeneous cores.

Is the 66AK2H06DXAAW2 pin-compatible with other devices in the 66AK2Hxx family?

The 66AK2H06DXAAW2 shares the same AAW 1517-pin BGA package and mechanical footprint with 66AK2H12DXAAW2 and 66AK2H14DXAAW2, but it is not fully pin-compatible due to functional differences. Specifically, XFI (10-GbE) pins present on 66AK2H14 are reserved (no-connect) on 66AK2H06DXAAW2, and certain HyperLink, PCIe, and timer signals differ in allocation. Board reuse requires schematic and layout review against the specific 66AK2H06DXAAW2 pin map in Section 4.2 of SPRS866G.

What security acceleration capabilities does the 66AK2H06DXAAW2 provide?

The 66AK2H06DXAAW2 includes a dedicated Security Accelerator supporting ECB, CBC, CTR, F8, A5/3, CCM, GCM, HMAC, CMAC, GMAC, AES, DES, 3DES, Kasumi, SNOW 3G, SHA-1, SHA-2 (256-bit hash), and MD5. It delivers up to 2.4 Gbps IPSec throughput and 2.4 Gbps air ciphering, offloading crypto operations from ARM and DSP cores. This capability is confirmed in Section 1.1 and Table 3-1 of the SPRS866G datasheet and applies identically across the 66AK2Hxx family, including the 66AK2H06DXAAW2.
