Texas Instruments 66AK2H06BAAW2

Overview

66AK2H06BAAW2 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 delivers 2.8 GHz aggregate ARM performance and 4.8 GHz aggregate DSP performance for media processing, analytics, and embedded infrastructure.

For engineers reviewing the 66AK2H06BAAW2 datasheet, 66AK2H06BAAW2 pinout, 66AK2H06BAAW2 application, or 66AK2H06BAAW2 equivalent, key selection criteria include dual DDR3 EMIF bandwidth, C66x+ARM co-processing capability, hardware-accelerated packet and security offload, and 1517-pin AAW BGA thermal/power routing constraints.

Technical Context

The 66AK2H06BAAW2 implements a heterogeneous multicore architecture where ARM Cortex-A15 cores handle OS-level tasks and control plane functions, while C66x DSP cores execute real-time signal, video, and packet processing in parallel. Its Multicore Navigator provides 16k hardware queues and zero-overhead packet DMA between peripherals and memory subsystems.

Hardware acceleration is distributed across dedicated coprocessors: the Network Coprocessor integrates Packet Accelerator (supporting GTP-U, SCTP, PDCP) and Security Accelerator (AES, SHA-2, HMAC, IPSec up to 2.4 Gbps), while the 5-port SGMII Ethernet switch enables wire-speed L2 forwarding without CPU intervention.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the ARM and DSP cores in the 66AK2H06BAAW2?

The 66AK2H06BAAW2 features two ARM Cortex-A15 processors operating at up to 1.4 GHz and four TMS320C66x DSP cores operating at up to 1.2 GHz. These frequencies are validated under extended temperature conditions (–40°C to 100°C) and require proper thermal management and voltage regulation per the recommended operating conditions in the SPRS866G datasheet. The 66AK2H06BAAW2 maintains full backward software compatibility with C64x+ DSP code.

Does the 66AK2H06BAAW2 support DDR3L memory, and what are the voltage requirements?

Yes, the 66AK2H06BAAW2 supports both DDR3 and DDR3L memory interfaces via its dual 72-bit EMIFs, operating at speeds up to 1600 MHz. DDR3L operation requires DVDD15 supply at 1.35 V (±3%), while standard DDR3 uses 1.5 V (±3%). The device's SmartReflex™ technology dynamically adjusts core voltage based on workload, but DDR3/DDR3L I/O voltage must be externally regulated and stable during initialization and runtime. This capability is explicitly documented in Revision G of the SPRS866G datasheet.

How many Ethernet ports does the 66AK2H06BAAW2 integrate, and what standards do they support?

The 66AK2H06BAAW2 integrates a five-port Gigabit Ethernet switch subsystem with four SGMII interfaces (1.25 Gbps each) and full IEEE 1588-2008 Annex D/E and SyncE support for precision time synchronization. It does not include 10-GbE (XFI) ports - those are exclusive to the 66AK2H14 variant. All five ports operate at wire speed with hardware-accelerated L2 forwarding, VLAN tagging, and QoS classification, enabling standalone switch functionality without external PHYs beyond the SGMII-connected devices.

What hardware security features are implemented in the 66AK2H06BAAW2?

The 66AK2H06BAAW2 includes a dedicated Security Accelerator supporting AES-128/256 (ECB/CBC/CTR/GCM), SHA-1/SHA-2 (256-bit), HMAC, CMAC, GMAC, DES/3DES, Kasumi, SNOW 3G, and air interface ciphering at up to 2.4 Gbps. It also provides memory protection via MPU for both MSMC SRAM and DDR3_EMIF, secure boot ROM with cryptographic signature verification, and JTAG lock-down capability. These features are fully enabled in production devices and documented in Section 11.16 of the SPRS866G datasheet.

Is the 66AK2H06BAAW2 pin-compatible with other members of the 66AK2Hxx family?

Yes, the 66AK2H06BAAW2 shares the identical 1517-pin AAW BGA package, mechanical footprint, and ball map with 66AK2H12BAAW2 and 66AK2H14BAAW2. All three variants use the same pinout - including reserved XFI pins in 66AK2H06BAAW2 - allowing single PCB design reuse across performance tiers. Differences are internal (core count, cache size, 10-GbE presence) and do not affect signal routing, power delivery, or thermal layout.
