Texas Instruments AM5K2E02ABD25

Overview

AM5K2E02ABD25 from Texas Instruments is a dual-core ARM Cortex-A15 KeyStone II System-on-Chip (SoC) operating at up to 1.25 GHz, integrating 4MB shared L2 cache, 2MB MSMC SRAM, and a 72-bit DDR3/DDR3L interface supporting 1600 MTPS. It delivers 8 Gbps total Ethernet bandwidth via eight SGMII ports and supports IEEE 1588 v2 with Annex D/E/F for precision time synchronization in enterprise networking infrastructure.

For engineers reviewing the AM5K2E02ABD25 datasheet, AM5K2E02ABD25 pinout, AM5K2E02ABD25 application, or AM5K2E02ABD25 equivalent, key selection criteria include dual-core Cortex-A15 performance at 1.25 GHz, integrated packet acceleration for 1 Gbps wire-speed IPsec/GTP-U/SCTP/PDCP, hardware-based security acceleration supporting AES/SHA-2/3DES/Kasumi, and 1089-pin ABD BGA packaging with industrial temperature range support.

Technical Context

The AM5K2E02ABD25 implements TI's KeyStone II architecture centered on TeraNet-a non-blocking multipoint-to-multipoint switch fabric enabling concurrent high-bandwidth data paths between cores, accelerators, and I/Os. Its Multicore Shared Memory Controller (MSMC) provides low-latency access to 2MB on-chip SRAM and DDR3 memory while maintaining cache coherency across dual Cortex-A15 cores.

Hardware offload is enabled through the Multicore Navigator with 8k configurable queues and a packet-based DMA engine, coupled with dedicated Network Coprocessor subsystems including Packet Accelerator (for transport-plane IPsec, GTP-U, SCTP, PDCP) and Security Accelerator (supporting ECB/CBC/CTR/F8/A5/3/CCM/GCM/AES/DES/3DES/Kasumi/SNOW 3G/SHA-1/SHA-2/MD5).

Key Specifications

FAQ

What is the maximum guaranteed operating frequency of the AM5K2E02ABD25?

The AM5K2E02ABD25 is rated for guaranteed operation at 1.25 GHz under commercial temperature conditions (0°C to 85°C). This speed is validated across process corners and voltage tolerances per TI's SPRS864D datasheet revision March 2015. The AM5K2E02ABD25 does not support 1.4 GHz operation-that rating applies only to the AM5K2E04ABD25 variant. Thermal design must maintain junction temperature below 105°C to sustain this frequency continuously.

Does the AM5K2E02ABD25 include hardware support for IEEE 1588 Precision Time Protocol?

Yes, the AM5K2E02ABD25 integrates full IEEE 1588 v2 hardware timestamping with support for Annex D (Transparent Clock), Annex E (Boundary Clock), and Annex F (Peer-to-Peer Transparent Clock). Each of its eight SGMII ports has dedicated timestamp registers and hardware match logic, enabling sub-microsecond timestamp accuracy without CPU involvement. This capability is confirmed in Section 1.1 and Table 10-18 of the SPRS864D datasheet.

How many Ethernet ports does the AM5K2E02ABD25 support, and what are their physical layer options?

The AM5K2E02ABD25 supports eight 1 Gbps SGMII ports with wire-rate switching and MACSEC encryption, plus two PCIe Gen2 controllers that can connect to external 10GbE PHYs. It does not integrate native 10GbE SerDes-those are present only in the AM5K2E04ABD25 variant. All eight SGMII interfaces operate at 1.25 Gbps with built-in clock recovery and auto-negotiation compliant with IEEE 802.3ab. No XAUI or KR support is included.

What type of on-chip memory is available in the AM5K2E02ABD25, and how is it allocated?

The AM5K2E02ABD25 includes 32 KB L1 instruction and 32 KB L1 data cache per Cortex-A15 core, a shared 4 MB L2 unified cache, and 2 MB of MSMC SRAM accessible by all cores and peripherals. The MSMC SRAM is error-correcting (ECC-protected) and functions as a coherent L3 cache or scratchpad memory. There is no embedded Flash or ROM beyond the 256 KB boot ROM. Memory mapping is fixed per Section 6.1 of SPRS864D, with DDR3 EMIF providing external expansion.

Is the Security Accelerator enabled by default in the AM5K2E02ABD25, and what cryptographic algorithms does it support?

The Security Accelerator in the AM5K2E02ABD25 is disabled by default and requires TI-specific configuration keys to activate-per footnote (2) in Table 3-1 of SPRS864D. When enabled, it supports ECB/CBC/CTR/F8/A5/3/CCM/GCM modes with AES-128/192/256, DES/3DES, Kasumi, SNOW 3G, SHA-1/SHA-2 (256-bit), HMAC, CMAC, GMAC, and MD5. Export-controlled functionality means activation is restricted to approved shipments only.
