FAQ

What is the maximum operating frequency of the Cortex-A5 core in SVF521R3K1CMK4?

The SVF521R3K1CMK4 features an ARM Cortex-A5 core rated for up to 500 MHz operation under specified voltage (3.0–3.6 V) and temperature (–40 °C to +85 °C) conditions. This frequency is confirmed in the Freescale VYBRIDFSERIESEC datasheet Rev 8, Section 2.3 "Part Number Format", where "50" in the speed field denotes 500 MHz. The core achieves 1.6 DMIPS/MHz and includes 32 KB I/D L1 cache and optional 512 KB L2 cache depending on variant.

Does SVF521R3K1CMK4 support IEEE 1588 Precision Time Protocol hardware timestamping?

Yes, SVF521R3K1CMK4 supports IEEE 1588 hardware timestamping through its dual 10/100 Ethernet subsystems. Each MAC includes dedicated timestamp registers and programmable event detection logic for ingress/egress packet marking with sub-100 ns resolution. This capability is documented in Section 9.3 of the VYBRIDFSERIESEC datasheet and enables precise time synchronization in industrial automation and power utility applications without external PHY timestamping assist.

What security features are implemented in SVF521R3K1CMK4 for secure boot and runtime protection?

SVF521R3K1CMK4 implements High Assurance Boot (HAB) with cryptographic signature verification of boot images, ARM TrustZone for hardware-isolated secure world execution, Cryptographic Acceleration and Assurance Module (CAAM) with AES-128/256, SHA-1/256, and RNG, plus Secure Non-Volatile Storage (SNVS) containing tamper-resistant RTC and secure key storage. These features are detailed in Sections 5 (Security) and 9.7 (Clocks and PLL Specifications) of the official datasheet.

Can SVF521R3K1CMK4 execute code directly from QuadSPI flash memory?

Yes, SVF521R3K1CMK4 supports Execute-in-Place (XIP) from QuadSPI flash via its dual QuadSPI controllers. The device boots directly from QuadSPI and allows instruction fetches with configurable wait states and caching - eliminating need for external parallel NOR/NAND flash. This is confirmed in Section 9.5.1 "QuadSPI timing" and Section 2.4 "Part Numbers" of the VYBRIDFSERIESEC datasheet, where QuadSPI is listed as primary boot source.

What is the package type and ball pitch of SVF521R3K1CMK4?

SVF521R3K1CMK4 uses a 364-ball MAPBGA package measuring 17 mm × 17 mm with 0.8 mm ball pitch and an exposed thermal pad on the underside. This package type is explicitly defined in the part number format documentation (Section 2.3) as "MK = 364 MAPBGA", and mechanical dimensions are provided in Section 11 "Dimensions" of the VYBRIDFSERIESEC datasheet Rev 8.
