Texas Instruments AM5K2E04XABDA4

Overview

AM5K2E04XABDA4 from Texas Instruments is a quad-core ARM Cortex-A15 KeyStone II System-on-Chip (SoC) operating at up to 1.4 GHz, integrating 4 MB shared L2 cache, 2 MB MSMC SRAM, and dual 72-bit DDR3/DDR3L interfaces supporting 1600 MTPS. It delivers 10-GbE switching, hardware-accelerated IPsec up to 6.4 Gbps, and IEEE 1588 v2 time synchronization - deployed in enterprise networking infrastructure and avionics data planes.

For engineers reviewing the AM5K2E04XABDA4 datasheet, AM5K2E04XABDA4 pinout, AM5K2E04XABDA4 application, or AM5K2E04XABDA4 equivalent, key selection criteria include its quad-core A15 performance envelope, integrated 10-GbE switch subsystem with MACSEC, hardware packet acceleration for PDCP/IPsec, and support for extended temperature operation (-40°C to +100°C).

Technical Context

The AM5K2E04XABDA4 implements TI's KeyStone II architecture centered on TeraNet-a non-blocking multipoint-to-multipoint switch fabric enabling concurrent high-bandwidth communication between cores, accelerators, and I/Os. Its Multicore Shared Memory Controller (MSMC) provides low-latency access to 2 MB on-chip SRAM and coherently manages DDR3 traffic across dual 72-bit EMIFs.

Hardware acceleration is distributed across three dedicated engines: Network Coprocessor handles L2/L3 packet processing including GTP-U and SCTP; Packet Accelerator offloads transport-layer functions like RoHC and PDCP; Security Accelerator executes AES, SHA-2, HMAC, and 3GPP air ciphering at up to 3 Gbps-each engine accessible via the Multicore Navigator's 8k hardware queue system with zero-overhead DMA transfers.

FAQ

What is the maximum DDR3 memory bandwidth supported by the AM5K2E04XABDA4?

The AM5K2E04XABDA4 supports dual 72-bit DDR3/DDR3L interfaces operating at up to 1600 MTPS, delivering a theoretical peak bandwidth of 25.6 GB/s (12.8 GB/s per channel). This bandwidth is sustained across both channels simultaneously and includes ECC overhead, enabling high-throughput data movement for packet buffering, flow table lookups, and real-time analytics in the AM5K2E04XABDA4-based system.

Does the AM5K2E04XABDA4 support IEEE 1588 v2 hardware timestamping?

Yes, the AM5K2E04XABDA4 provides full hardware implementation of IEEE 1588 v2 with Annex D, E, and F support. Its TSIP peripheral enables sub-100 ns packet timestamping accuracy on all eight SGMII and both XFI ports, with dedicated hardware for PTP event message detection, correction of asymmetry, and transparent clock functionality-critical for telecom synchronization and avionics deterministic networks.

What security algorithms does the AM5K2E04XABDA4 Security Accelerator support?

The AM5K2E04XABDA4 Security Accelerator supports ECB, CBC, CTR, F8, A5/3, CCM, GCM, HMAC, CMAC, GMAC, AES (128/192/256), DES, 3DES, Kasumi, SNOW 3G, SHA-1, SHA-2 (224/256/384/512), and MD5. These are executed in parallel across dedicated micro-RISC engines, enabling up to 6.4 Gbps IPSec and 3 Gbps air ciphering throughput without CPU intervention.

Can the AM5K2E04XABDA4 operate in extended temperature environments?

Yes, the AM5K2E04XABDA4 is rated for extended case temperature operation from -40°C to +100°C. This rating is validated across all functional blocks-including DDR3 I/O, PCIe SerDes, SGMII/XFI transceivers, and security accelerators-and is reflected in the 'A' suffix of its part number (AM5K2E04XABDA4), making it suitable for deployment in uncontrolled avionics bays and outdoor telecom cabinets.

How many PCIe Gen2 lanes does the AM5K2E04XABDA4 provide?

The AM5K2E04XABDA4 integrates two PCIe Gen2 controllers, each supporting two lanes for a total of four PCIe Gen2 lanes. Each controller operates at 5 GT/s with full link training, ASPM, and MSI-X support, enabling connection to external NICs, FPGA accelerators, or storage controllers while maintaining full x2 lane bandwidth per controller.
