Texas Instruments 66AK2H06DAAWA24

Overview

66AK2H06DAAWA24 from Texas Instruments is a multicore DSP+ARM System-on-Chip (SoC) integrating four TMS320C66x DSP cores and two ARM Cortex-A15 processors, delivering up to 4.8 GHz combined DSP compute (1.2 GHz × 4) and 2.8 GHz ARM compute (1.4 GHz × 2), with 6 MB shared MSMC SRAM, dual 72-bit DDR3/DDR3L interfaces (up to 1600 MHz), and hardware-accelerated packet and security processing - deployed in media transcoding, wireless baseband, and network infrastructure equipment.

For engineers reviewing the 66AK2H06DAAWA24 datasheet, 66AK2H06DAAWA24 pinout, 66AK2H06DAAWA24 application, or 66AK2H06DAAWA24 equivalent, key selection considerations include its 4-C66x + 2-A15 core configuration, 14 × 64-bit timers, 5-port Gigabit Ethernet switch, PCIe Gen2 x2, SRIO 2.1 (4 lanes), and support for IEEE 1588 time synchronization in telecom and broadcast systems.

Technical Context

The 66AK2H06DAAWA24 implements KeyStone II architecture with tightly coupled ARM and DSP subsystems sharing a 6 MB MSMC SRAM with memory protection unit (MPU), enabling low-latency inter-processor communication. Its Multicore Navigator provides 16k hardware queues and packet-based DMA for zero-overhead data movement between peripherals and cores.

Network Coprocessor integrates Packet Accelerator (supporting GTP-U, SCTP, PDCP, RoHC) and Security Accelerator (AES, SHA-2, HMAC, IPSec up to 2.4 Gbps), while the 5-port Gigabit Ethernet switch supports SGMII with IEEE 1588 Annex D/E and SyncE for precise timing in packet-based transport networks.

FAQ

What is the maximum operating frequency of the C66x DSP cores in the 66AK2H06DAAWA24?

The 66AK2H06DAAWA24 features four TMS320C66x DSP cores each operating at up to 1.2 GHz, delivering 38.4 GMACs/core for fixed-point and 19.2 GFLOPs/core for floating-point computation - confirmed in SPRS866G Rev G Section 1.1 and Table 3-1. This frequency is supported across commercial temperature range (0°C to 85°C case).

Does the 66AK2H06DAAWA24 support IEEE 1588 Precision Time Protocol?

Yes, the 66AK2H06DAAWA24 includes hardware timestamping and correction engines compliant with IEEE 1588 Annex D/E and SyncE standards, as documented in Section 1.1 Features and Section 11.17 of SPRS866G. It enables sub-100 ns time accuracy in packet timing applications without CPU intervention.

How many DDR3 memory interfaces does the 66AK2H06DAAWA24 provide?

The 66AK2H06DAAWA24 integrates two independent 72-bit DDR3/DDR3L memory controllers supporting data rates up to 1600 MHz, providing 12.8 GB/s aggregate bandwidth. This is explicitly stated in Section 1.1 Features and Table 3-1 of SPRS866G, and applies identically to all 66AK2Hxx variants including 66AK2H06DAAWA24.

What is the package type and pin count of the 66AK2H06DAAWA24?

The 66AK2H06DAAWA24 uses a 1517-pin flip-chip plastic BGA package (AAW) with 40.0 mm × 40.0 mm body size and 0.8 mm ball pitch, as specified in Section 13.1 and Table 3-1 of SPRS866G. Pin assignments are fully detailed in Figures 4-1 through 4-6.

Is the 66AK2H06DAAWA24 pin-compatible with other 66AK2Hxx devices like the 66AK2H12 or 66AK2H14?

No - while the 66AK2H06DAAWA24 shares the same AAW package footprint and ball grid layout with 66AK2H12 and 66AK2H14, it is not functionally pin-compatible due to disabled 10-GbE XFI pins (reserved in 66AK2H06 per Figure 4-1 and Section 4.1) and reduced timer count (14 vs. 20). Board designs must be verified per device-specific pin maps.
