Texas Instruments 66AK2H06DAAW24

Overview

66AK2H06DAAW24 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), 6 MB MSMC SRAM, dual 72-bit DDR3/DDR3L interfaces (1600 MHz), and a 5-port Gigabit Ethernet switch. It delivers 2.8 GHz aggregate ARM + 4.8 GHz aggregate DSP performance for media processing, analytics, and embedded infrastructure.

For engineers reviewing the 66AK2H06DAAW24 datasheet, 66AK2H06DAAW24 pinout, 66AK2H06DAAW24 application, or 66AK2H06DAAW24 equivalent, key selection factors include its 14 × 64-bit timers, SmartReflex™ core voltage scaling, PCIe Gen2 x2 support, HyperLink scalability, and 1517-pin AAW BGA package with 40 mm × 40 mm footprint.

Technical Context

The 66AK2H06DAAW24 implements a heterogeneous multicore architecture where ARM Cortex-A15 cores handle high-level OS tasks and control plane functions, while C66x DSP cores execute real-time signal, video, and packet processing. Its Multicore Navigator provides 16k hardware queues and zero-overhead packet-based DMA, tightly coupled with the Network Coprocessor's Packet Accelerator (supporting GTP-U, SCTP, PDCP) and Security Accelerator (AES, SHA-2, IPSec up to 2.4 Gbps).

Memory coherency is maintained via AMBA 4.0 ACE master ports linking ARM L2 cache (4 MB shared) and C66x L2 caches (1024 KB per core) to the 6 MB MSMC SRAM. The device uses five on-chip PLLs for independent clock domain management across ARM, DSP, DDR3, PCIe, and peripheral subsystems - critical for deterministic latency in telecom and media infrastructure applications.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the ARM and DSP cores in the 66AK2H06DAAW24?

The 66AK2H06DAAW24 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 (0°C to 85°C case temperature) with proper power delivery and thermal management. The 66AK2H06DAAW24 does not support higher-frequency variants like the 66AK2H14's 1.6 GHz DSP option.

Does the 66AK2H06DAAW24 support DDR3L memory, and what are the voltage requirements?

Yes, the 66AK2H06DAAW24 supports both DDR3 and DDR3L memory interfaces via its dual 72-bit EMIFs, operating at speeds up to 1600 MHz. DDR3L compatibility requires DVDD15 supply set to 1.35 V (±3%), while standard DDR3 uses 1.5 V (±3%). Both modes are supported simultaneously across the two interfaces, enabling mixed-memory configurations in the same system.

How many Ethernet ports does the 66AK2H06DAAW24 integrate, and what standards do they support?

The 66AK2H06DAAW24 integrates a five-port Gigabit Ethernet switch subsystem with four SGMII ports supporting IEEE 802.3ab (1000BASE-T) and IEEE 1588-2008 Annex D/E for precision time synchronization. It does not include XFI or 10-GbE ports - those are exclusive to the 66AK2H14 variant. All ports support full-duplex operation, jumbo frames, and hardware timestamping.

What debug and emulation interfaces are available on the 66AK2H06DAAW24?

The 66AK2H06DAAW24 provides IEEE 1149.1 JTAG (TCK/TMS/TDI/TDO/TRST) for boundary-scan and core debugging, plus 24 dedicated emulator pins (EMU00–EMU18) supporting real-time trace, instruction-level stepping, and memory access via TI's Code Composer Studio. It also includes SWD-compatible signals for ARM core debugging and dedicated trace ports for C66x core visibility.

Is the 66AK2H06DAAW24 pin-compatible with other members of the 66AK2Hxx family, such as the 66AK2H12 or 66AK2H14?

Yes, the 66AK2H06DAAW24 shares identical pinout, package (AAW), and ball assignment with the 66AK2H12DAAW24 and 66AK2H14DAAW24. However, certain pins - notably the 14 XFI lanes used for 10-GbE in the 66AK2H14 - are reserved (no connect) in the 66AK2H06DAAW24. This allows direct PCB reuse across the family, though firmware and power delivery must be adapted to each variant's core count and feature set.
