Overview
XC7K420T-1FFG901C from AMD is a Kintex-7 FPGA with 419,400 logic cells, 2,080 DSP slices, and 28.5 Mb of block RAM, packaged in a 901-pin Flip-Chip Fine-Pitch Ball Grid Array (FFG) with 0.8 mm pitch. It targets high-throughput data processing in radar signal conditioning and PCIe Gen2 endpoint interfaces.
For engineers reviewing the XC7K420T-1FFG901C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O bank voltage support (1.2 V to 3.3 V), transceiver line rates up to 6.6 Gb/s, thermal performance under 100°C junction, and configuration via Master SelectMAP or JTAG.
Technical Context
The XC7K420T-1FFG901C implements a 28 nm HKMG process architecture with configurable logic blocks (CLBs), dedicated DSP48E1 slices for arithmetic acceleration, and built-in PCI Express® v2.1 hard IP. It supports multi-gigabit transceivers compliant with SATA, SRIO, and CPRI protocols.
Configuration occurs through dual-mode SPIx4 or BPI parallel interface, with bitstream encryption enabled via AES-256 and HMAC-SHA-256. The device includes integrated clock management tiles (CMTs) with MMCM and PLL blocks supporting jitter < 150 ps RMS over 12 kHz–20 MHz bandwidth.

Does XC7K420T-1FFG901C include hard IP for PCI Express?
Yes, XC7K420T-1FFG901C integrates a PCIe Gen2 x8 endpoint hard IP block. It supports link widths from x1 to x8, root port or endpoint roles, and features AXI4 streaming interfaces. The hard IP consumes zero programmable logic resources and delivers sub-500 ns transaction latency, as confirmed in UG476 Table 1-2.
What configuration modes are supported by XC7K420T-1FFG901C?
XC7K420T-1FFG901C supports Master SPI, Slave SPI, Master SelectMAP, Slave SelectMAP, and JTAG configuration modes. Mode selection is controlled by M0–M2 pins at power-on. BPI parallel mode requires external flash with x16 data bus; Master SPI uses quad-SPI flash with single/dual/quad I/O capability.
Is bitstream encryption available on XC7K420T-1FFG901C?
Yes, XC7K420T-1FFG901C supports AES-256 bitstream encryption with HMAC-SHA-256 authentication. Encryption keys are stored in on-chip eFUSE and protected against readback. This feature prevents unauthorized duplication and ensures intellectual property protection, as documented in UG476 Chapter 7.
What is the I/O voltage range supported per bank on XC7K420T-1FFG901C?
XC7K420T-1FFG901C supports I/O voltages from 1.2 V to 3.3 V per bank, with independent VCCO supply per bank. Each bank can be configured for LVCMOS, LVTTL, SSTL, HSTL, or differential standards including LVDS and TMDS. Bank 0–15 and 32–34 support 1.2 V to 1.8 V; banks 16–31 support 1.5 V to 3.3 V.
