FAQ

What is the maximum operating frequency of the AM5K2E02XABD25?

The AM5K2E02XABD25 operates at a maximum core frequency of 1.25 GHz, as indicated by the "25" suffix in its part number per TI's nomenclature. This speed is guaranteed under commercial temperature conditions (0°C to 85°C) with appropriate voltage scaling and thermal management. The device supports SmartReflex automatic voltage scaling to optimize power versus performance across varying workloads. All timing specifications in the SPRS864D datasheet are validated at this rated frequency.

Does the AM5K2E02XABD25 support IEEE 1588 Precision Time Protocol?

Yes, the AM5K2E02XABD25 fully supports IEEE 1588 v2 with Annex D, E, and F, providing hardware timestamping, transparent clock correction, and boundary clock functionality. Its Ethernet subsystem integrates dedicated timestamp units on all SGMII and XFI ports, enabling sub-100 ns time synchronization accuracy. This capability is essential for TSN, AFDX, and telecom synchronization applications where deterministic latency and phase alignment are required.

What memory interfaces does the AM5K2E02XABD25 include?

The AM5K2E02XABD25 includes a 72-bit DDR3/DDR3L external memory interface (EMIF) supporting data rates up to 1600 MTPS, and an EMIF16 interface for NAND/NOR flash. It also integrates 4 MB of shared L2 cache and 2 MB of MSMC SRAM with ECC protection. The DDR3 interface uses 1.35 V or 1.5 V I/O voltage and supports interleaved burst modes for optimized packet buffer access in networking applications.

Is the Security Accelerator enabled on the AM5K2E02XABD25?

No-the "X" in AM5K2E02XABD25 denotes an experimental device variant, and the Security Accelerator is disabled per TI's nomenclature. The suffix "X" indicates the device is intended for internal evaluation only and lacks production-level security key provisioning. For production use with enabled Security Accelerator, select AM5K2E02ABD25 (blank suffix) or AM5K2E02DABD25 (high-security variant with TI developmental keys).

What package type and pin count does the AM5K2E02XABD25 use?

The AM5K2E02XABD25 uses a 1089-pin Flip-Chip Plastic BGA (FCBGA) package with ABD mechanical outline (27 mm × 27 mm). This package supports fine-pitch ball placement for high-density routing of DDR3, PCIe, SGMII, and XFI signals. Thermal and mechanical data-including solder paste stencil recommendations and reflow profiles-are documented in Section 11 of the SPRS864D datasheet.
