Product details
Overview
XC7K420T-1FFG1156C from AMD (Xilinx) is a high-performance Kintex-7 FPGA with 419,400 logic cells, 2,040 DSP slices, and 28.5 Mb of block RAM, packaged in a 1156-pin Flip-Chip Fine-Pitch Ball Grid Array (FC-FBGA). It targets high-bandwidth data processing in wired communications infrastructure and radar signal conditioning.
For engineers reviewing the XC7K420T-1FFG1156C datasheet, pinout, applications, or equivalent options, key selection factors include I/O voltage support (1.2 V to 3.3 V), transceiver line rates up to 13.1 Gb/s, thermal performance in industrial temperature grade, and configuration interface options (JTAG, SelectMAP, SPI).
Technical Context
The XC7K420T-1FFG1156C implements a 28 nm HKMG process-based architecture with configurable logic blocks (CLBs), hardened PCIe Gen2/Gen3 endpoints, and multi-gigabit transceivers compliant with IEEE 802.3ba and CPRI standards. It supports partial reconfiguration and AXI4-Stream interfaces for real-time data path adaptation.
Configuration is performed via dual-boot SPI flash or JTAG, with bitstream encryption using AES-256 and HMAC authentication. The device integrates dedicated clock management tiles (CMTs) containing PLLs and MMCMs for jitter attenuation and frequency synthesis across multiple domains.
