Texas Instruments 66AK2H14BAAWA24

Overview

66AK2H14BAAWA24 from Texas Instruments is a KeyStone II–based multicore SoC integrating four ARM Cortex-A15 processors (up to 1.4 GHz) and eight TMS320C66x DSP cores (up to 1.2 GHz), 6 MB shared 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 transcoding and packet processing in telecom infrastructure.

For engineers reviewing the 66AK2H14BAAWA24 datasheet, 66AK2H14BAAWA24 pinout, 66AK2H14BAAWA24 application, or 66AK2H14BAAWA24 equivalent, key selection factors include its 10-GbE support (XFI), 20 × 64-bit timers, PCIe Gen2 x2, SRIO 2.1 (4 lanes), and hardware-accelerated security (IPsec, GCM, SHA-2) - all in a 1517-pin AAW BGA package.

Technical Context

The 66AK2H14BAAWA24 implements a tightly coupled heterogeneous architecture where ARM cores handle OS-level control and protocol stacks while C66x DSPs execute real-time signal, video, and packet processing tasks. Its Multicore Navigator provides 16k hardware queues and zero-overhead packet DMA, enabling deterministic data movement across ARM, DSP, and accelerators.

The Network Coprocessor integrates independent Packet Accelerator and Security Accelerator engines: the former supports L2/L3 offloads (GTP-U, SCTP, PDCP) at 1.5 Mpps wire speed; the latter delivers up to 2.4 Gbps IPSec and air ciphering (Kasumi, SNOW 3G) with AES, SHA-2, and HMAC acceleration.

Key Specifications

FAQ

What is the maximum operating frequency of the ARM and DSP cores in the 66AK2H14BAAWA24?

The 66AK2H14BAAWA24 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 guaranteed under recommended operating conditions (0°C to 85°C commercial or –40°C to 100°C extended temperature range) with proper power delivery and thermal management. The 66AK2H14BAAWA24 achieves 5.6 GHz aggregate ARM compute and 9.6 GHz aggregate DSP compute at these speeds.

Does the 66AK2H14BAAWA24 support DDR3L memory, and what are the voltage requirements?

Yes, the 66AK2H14BAAWA24 supports both DDR3 and DDR3L memory via its dual 72-bit interfaces, operating at data rates up to 1600 MT/s. The DDR3 I/O voltage (DVDD15) is configurable at either 1.35 V or 1.5 V, matching DDR3L or standard DDR3 specifications respectively. This flexibility allows system designers to optimize power consumption or maintain compatibility with existing DDR3 modules.

How many 10-GbE interfaces does the 66AK2H14BAAWA24 provide, and what physical layer standard do they use?

The 66AK2H14BAAWA24 provides two 10-GbE interfaces implemented as XFI (10 Gigabit Attachment Unit Interface) ports, supporting direct AC-coupled connections to optical transceivers. These interfaces comply with IEEE 802.3ae and include full IEEE 1588-2008 Annex D/E time synchronization support for precision timing in telecom applications.

What hardware accelerators are integrated into the 66AK2H14BAAWA24, and what protocols do they support?

The 66AK2H14BAAWA24 integrates two dedicated hardware accelerators: the Packet Accelerator supports GTP-U, SCTP, PDCP, RoHC, and L2 user-plane ciphering; the Security Accelerator supports IPsec (ESP/AH), SRTP, 3GPP air interface (Kasumi, SNOW 3G), SSL/TLS, and cryptographic primitives including AES, SHA-2, HMAC, and GCM. Together, they deliver up to 2.4 Gbps encrypted throughput.

Is the 66AK2H14BAAWA24 pin-compatible with other devices in the 66AK2Hxx family, such as the 66AK2H12 or 66AK2H06?

Yes, the 66AK2H14BAAWA24 shares the same 1517-ball AAW BGA package, pinout, and mechanical footprint with the 66AK2H12BAAWA24 and 66AK2H06BAAWA24. However, 14 XFI pins reserved for 10-GbE in the 66AK2H14 are NC (no-connect) in the 66AK2H12/06 variants - meaning PCBs designed for the 66AK2H14BAAWA24 can accommodate lower-tier variants, but not vice versa without redesign.
