Texas Instruments 66AK2H14DAAW24

Overview

66AK2H14DAAW24 from Texas Instruments is a KeyStone II multicore SoC integrating four ARM Cortex-A15 processors (up to 1.4 GHz), eight C66x DSP cores (up to 1.2 GHz), 6 MB MSMC SRAM, dual 72-bit DDR3/DDR3L interfaces (1600 MHz), and a 10-GbE switch subsystem with two XFI ports. It delivers 5.6 GHz ARM + 9.6 GHz DSP compute for media processing, cloud infrastructure, and secure networking.

For engineers reviewing the 66AK2H14DAAW24 datasheet, 66AK2H14DAAW24 pinout, 66AK2H14DAAW24 application, or 66AK2H14DAAW24 equivalent, key selection criteria include 10-GbE XFI support, 20 × 64-bit timers, SmartReflex™ voltage scaling, IEEE 1588 time synchronization, and hardware-accelerated IPsec/air ciphering up to 2.4 Gbps.

Technical Context

The 66AK2H14DAAW24 implements a heterogeneous multicore architecture where ARM A15 cores handle OS, control, and high-level protocol stacks while C66x DSPs execute real-time signal, video, and packet processing in parallel. Its Multicore Navigator provides 16k hardware queues and zero-overhead packet DMA across all processing elements.

Key interconnects include TeraNet for low-latency core-to-core communication, MSMC with MPU-enforced memory protection for shared 6 MB SRAM, and dedicated ACE master ports enabling cache coherency between ARM L2 and MSMC. The Network Coprocessor offloads transport- and link-layer functions including GTP-U, PDCP, RoHC, and 10-GbE switching.

Key Specifications

Pinout & Package

The 66AK2H14DAAW24 uses a 1517-pin flip-chip plastic BGA (AAW) package measuring 40.0 mm × 40.0 mm with 0.8 mm ball pitch. Thermal and power integrity are maintained via dedicated CVDD, DVDD15, DVDD18, VDDAHV, and VDDALV supply domains distributed across the array.

FAQ

What is the maximum operating frequency of the ARM and DSP cores in the 66AK2H14DAAW24?

The 66AK2H14DAAW24 integrates four ARM Cortex-A15 processors operating up to 1.4 GHz and eight TMS320C66x DSP cores operating up to 1.2 GHz. These frequencies are validated under extended temperature conditions (–40°C to 100°C) with appropriate power delivery and thermal management. The 66AK2H14DAAW24 achieves 5.6 GHz aggregate ARM performance and 9.6 GHz aggregate DSP performance at these rated speeds.

Does the 66AK2H14DAAW24 support DDR3L memory, and what are the voltage requirements?

Yes, the 66AK2H14DAAW24 supports both DDR3 and DDR3L memory interfaces across its dual 72-bit channels, operating at data rates up to 1600 MHz. The DDR3L interface accepts 1.35 V supply, while standard DDR3 uses 1.5 V; both are supported by the DVDD15 power domain. The 66AK2H14DAAW24 datasheet specifies 1.35/1.5 V as the recommended operating range for DVDD15 to accommodate either memory type.

How many 10-GbE interfaces does the 66AK2H14DAAW24 provide, and what physical layer standards do they implement?

The 66AK2H14DAAW24 provides two 10-GbE interfaces implemented as XFI ports compliant with IEEE 802.3ae 10GBASE-R. Each port supports 10.3125 Gbps serial line rate with embedded clocking, and includes hardware support for IEEE 1588-2008 Annex D/E and SyncE for precision time synchronization. These interfaces are distinct to the 66AK2H14DAAW24 and omitted in lower-tier variants like the 66AK2H12DAAW24.

What hardware accelerators are integrated into the 66AK2H14DAAW24 for network processing?

The 66AK2H14DAAW24 integrates a dedicated Network Coprocessor containing a Packet Accelerator and Security Accelerator. The Packet Accelerator supports transport-layer protocols including GTP-U, SCTP, and PDCP, plus L2 user-plane functions like RoHC and air ciphering. The Security Accelerator implements AES, SHA-2, HMAC, and Kasumi algorithms, delivering up to 2.4 Gbps IPsec and 2.4 Gbps air ciphering throughput - all offloaded from the ARM and DSP cores.

Is the 66AK2H14DAAW24 pin-compatible with other devices in the 66AK2Hxx family, such as the 66AK2H12DAAW24?

No, the 66AK2H14DAAW24 is not fully pin-compatible with the 66AK2H12DAAW24. While both use the same 1517-pin AAW BGA package and share most signal assignments, the 66AK2H14DAAW24 allocates 14 dedicated balls for its two XFI 10-GbE interfaces (e.g., XFIRXP0, XFITXP1), which are reserved (NOPIN) in the 66AK2H12DAAW24. PCB layout must be specific to the 66AK2H14DAAW24 to route these high-speed differential pairs.
