Product details
Overview
AM5K2E04XABD25 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 a 72-bit DDR3/DDR3L interface supporting 1600 MTPS. It delivers 8 Gbps total Ethernet bandwidth via eight SGMII ports and two 10-GbE switch subsystems with MACSEC and IEEE 1588 v2 support, targeting high-throughput networking infrastructure.
For engineers reviewing the AM5K2E04XABD25 datasheet, AM5K2E04XABD25 pinout, AM5K2E04XABD25 application, or AM5K2E04XABD25 equivalent, key selection criteria include quad-core Cortex-A15 performance, integrated network coprocessor (packet accelerator + security accelerator), PCIe Gen2 dual-controller support, and extended temperature operation (–40°C to +100°C) in the 1089-pin ABD BGA package.
Technical Context
The AM5K2E04XABD25 implements TI's KeyStone II architecture centered on TeraNet-a non-blocking multipoint-to-multipoint switch fabric-and the Multicore Shared Memory Controller (MSMC), which provides low-latency access to 2 MB on-chip SRAM and DDR3 memory. Its ARM CorePac includes full ARMv7-A compliance, LPAE, virtualization extensions, and ACE coherency for multi-core cache consistency.
Network processing is offloaded via dedicated hardware blocks: the Network Coprocessor handles transport-plane IPsec, GTP-U, SCTP, and L2 PDCP; the Security Accelerator supports AES, SHA-2, HMAC, GMAC, and 3GPP/WiMAX air ciphering at up to 6.4 Gbps IPSec throughput; and the Multicore Navigator manages 8k hardware queues with packet-based DMA for zero-overhead transfers.
