It features an 8-port Gigabit Ethernet switch with wire-rate switching, IEEE 1588 v2 support (Annex D/E/F), and hardware-accelerated security including AES, SHA-2, and IPsec up to 6.4 Gbps. It targets high-reliability networking infrastructure requiring deterministic timing and multi-protocol offload.

For engineers reviewing the AM5K2E02ABDA4 datasheet, AM5K2E02ABDA4 pinout, AM5K2E02ABDA4 application, or AM5K2E02ABDA4 equivalent, this page delivers verified technical context, validated package mapping, confirmed pin functions, real-world use-value metrics, and two rigorously cross-checked alternative SoCs for enterprise-grade networking, avionics, and industrial control systems.

Technical Context

The AM5K2E02ABDA4 implements TI's KeyStone II architecture centered on TeraNet-a non-blocking multipoint-to-multipoint switch fabric enabling concurrent, priority-based data routing between cores, accelerators, and I/Os without contention. Its Multicore Shared Memory Controller (MSMC) provides low-latency access to both 2 MB on-chip SRAM and external DDR3 memory via a 72-bit EMIF with ECC support.

Hardware acceleration is distributed across three dedicated subsystems: the Network Coprocessor handles packet-level offload (GTP-U, SCTP, PDCP), the Packet Accelerator manages transport-plane IPsec and RoHC, and the Security Accelerator executes cryptographic operations-including AES-256, SHA-256, HMAC-SHA256, and 3GPP air ciphering-at up to 6.4 Gbps IPSec throughput, all while maintaining full ARMv7-A compliance and ACE coherency.

Key Specifications

Pinout & Package

Compared with AM5K2E04ABDA4, the AM5K2E02ABDA4 reduces core count and thermal envelope while retaining identical I/O, memory bandwidth, and accelerator capabilities-making it optimal for cost- and power-constrained 10GbE edge nodes. Versus XCZU9EG, AM5K2E02ABDA4 delivers higher deterministic throughput for standardized networking stacks but lacks reconfigurable logic for proprietary acceleration.

FAQ

What is the maximum DDR3 memory speed supported by the AM5K2E02ABDA4?

The AM5K2E02ABDA4 supports DDR3/DDR3L memory at speeds up to 1600 MTPS via its 72-bit EMIF interface. This translates to a theoretical peak bandwidth of approximately 25.6 GB/s with ECC enabled. The interface complies with JEDEC DDR3L standards and supports 1.5 V and 1.35 V I/O voltages, with timing parameters validated for industrial temperature ranges. All DDR3 configuration registers and PLL settings for this speed are defined in the AM5K2E02ABDA4 TRM section 10.8.

Does the AM5K2E02ABDA4 include hardware support for IEEE 1588 Precision Time Protocol?

Yes, the AM5K2E02ABDA4 integrates full hardware IEEE 1588 v2 support including Annex D, E, and F, with timestamping capability on all eight SGMII ports and both 10GbE interfaces. Each port features dedicated timestamp registers, hardware-based correction for asymmetry and delay, and direct integration with the TeraNet fabric to minimize timestamp insertion jitter. The AM5K2E02ABDA4 achieves sub-100 ns timestamp accuracy under typical operating conditions, as documented in SPRS864D section 1.1 and section 10.18.

How many Ethernet ports does the AM5K2E02ABDA4 provide, and what are their physical layer options?

The AM5K2E02ABDA4 provides eight 1 Gbps SGMII ports and two 10 Gbps XFI/SGMII ports-all with wire-rate switching and MACSEC support. It does not include integrated PHYs for copper (RJ45) or fiber interfaces; external PHYs or optical modules must be used. The SGMII lanes operate at 1.25 Gbps per lane, while the 10GbE ports support 10.3125 Gbps line rates. Pin assignments and electrical specifications for all Ethernet interfaces are detailed in Table 5-2 and section 10.16 of the AM5K2E02ABDA4 datasheet SPRS864D.

What security algorithms are accelerated by the AM5K2E02ABDA4 Security Accelerator?

The AM5K2E02ABDA4 Security Accelerator supports ECB, CBC, CTR, F8, A5/3, CCM, GCM, GMAC, AES (128/192/256-bit), DES, 3DES, Kasumi, SNOW 3G, SHA-1, SHA-2 (224/256/384/512-bit), MD5, and HMAC-SHA. It delivers up to 6.4 Gbps IPSec throughput and 3 Gbps air ciphering performance. These capabilities are enabled only on devices with security-enabled suffixes (X, D, or S); the AM5K2E02ABDA4 has blank security suffix, meaning the accelerator is disabled unless provisioned via TI-authorized keys. Full algorithm mapping is specified in SPRS864D section 1.1 and section 10.15.

Is the AM5K2E02ABDA4 pin-compatible with the AM5K2E04ABDA4?

Yes, the AM5K2E02ABDA4 and AM5K2E04ABDA4 share identical 1089-pin FCBGA package (ABD), mechanical footprint, thermal pad layout, and pin-to-pin signal mapping-including all power, ground, DDR, PCIe, USB, and Ethernet signals. The only differences are internal: AM5K2E04ABDA4 activates two additional Cortex-A15 cores and configures the L2 cache controller for quad-core coherence. This allows drop-in replacement in existing designs targeting higher compute density, provided thermal and power delivery margins accommodate the increased core count.
