Texas Instruments X66AK2H06AAAW2

Overview

X66AK2H06AAAW2 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 and 4.8 GHz aggregate DSP processing for media infrastructure and packet-processing applications.

For engineers reviewing the X66AK2H06AAAW2 datasheet, X66AK2H06AAAW2 pinout, X66AK2H06AAAW2 application, or X66AK2H06AAAW2 equivalent, key selection considerations include its 1517-pin AAW BGA package, 14 × 64-bit timers, SmartReflex™ core voltage scaling, and support for IEEE 1588 time synchronization in telecom edge nodes.

Technical Context

The X66AK2H06AAAW2 implements a heterogeneous multicore architecture where the ARM CorePac handles OS-level tasks and system control while the C66x DSP CorePacs execute real-time signal processing, with coherent interconnect via AMBA 4.0 ACE and TeraNet. Its Multicore Navigator provides 16k hardware queues and zero-overhead packet DMA for offloading data movement from CPU cores.

Network Coprocessor integration includes dedicated Packet Accelerator (supporting GTP-U, SCTP, PDCP, RoHC) and Security Accelerator (AES, SHA-2, HMAC, IPSec up to 2.4 Gbps), both operating independently of main CPU clusters. The 5-port SGMII Ethernet switch subsystem supports full wire-speed 1-Gbps forwarding with IEEE 1588 Annex D/E and SyncE timing support.

Key Specifications

Pinout & Package

The X66AK2H06AAAW2 is housed in a 1517-ball flip-chip plastic BGA (package code AAW), 40 mm × 40 mm, with 1.0 mm ball pitch. Ball assignment follows TI's standardized AAW pin map; 10-GbE XFI pins are reserved (no-connect) in this variant.

FAQ

What is the maximum operating frequency of the ARM and DSP cores in the X66AK2H06AAAW2?

The X66AK2H06AAAW2 integrates 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 X66AK2H06AAAW2 does not support higher-frequency variants like the 66AK2H14's 1.6 GHz DSP option.

Does the X66AK2H06AAAW2 support IEEE 1588 Precision Time Protocol?

Yes, the X66AK2H06AAAW2 includes hardware timestamping engines integrated into each of its five SGMII Ethernet MACs, supporting IEEE 1588-2008 Annex D/E and SyncE standards. This enables sub-100 ns timestamp resolution for telecom synchronization in mobile backhaul and fronthaul applications. The X66AK2H06AAAW2 requires external PHYs with PTP-capable MDIO registers for full boundary clock implementation.

How many DDR3 memory channels does the X66AK2H06AAAW2 support, and what is the maximum data rate?

The X66AK2H06AAAW2 supports two independent 72-bit DDR3/DDR3L memory controllers, each capable of 1600 MT/s data rates. Each channel includes on-die termination, dynamic ODT control, and ECC support for 8-bit correction. Total theoretical bandwidth is 25.6 GB/s, shared across ARM, DSP, and accelerator subsystems via the MSMC interconnect.

What differentiates the X66AK2H06AAAW2 from the X66AK2H12AAAW2 in terms of core count and timer resources?

The X66AK2H06AAAW2 contains two ARM Cortex-A15 cores and four C66x DSP cores, whereas the X66AK2H12AAAW2 has four ARM cores and eight DSP cores. Timer count differs accordingly: the X66AK2H06AAAW2 provides fourteen 64-bit configurable timers, while the X66AK2H12AAAW2 offers twenty. Both share identical peripherals including the 5-port SGMII switch and Packet Accelerator.

Is the X66AK2H06AAAW2 pin-compatible with other devices in the 66AK2Hxx family?

Yes, the X66AK2H06AAAW2 shares the same 1517-pin AAW BGA package and mechanical footprint with the X66AK2H12AAAW2 and X66AK2H14AAAW2. All three devices use identical ball mapping for power, ground, DDR3, SGMII, PCIe, HyperLink, and UART interfaces. Reserved balls (e.g., XFI for 10-GbE) are consistent across variants, enabling single PCB design reuse across performance tiers.
