Product details
Overview
XC4020XL-3PQ160I from Xilinx is a Field-Programmable Gate Array (FPGA) with 20,000 usable gates, 160-pin Plastic Quad Flat Package (PQFP), -3 speed grade (12.5 ns CLB propagation delay), and industrial temperature range (-40°C to +100°C). It implements synchronous digital logic in embedded control, protocol bridging, and real-time signal conditioning systems.
For engineers reviewing the XC4020XL-3PQ160I datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, I/O count (118 user I/Os), speed grade timing, PQFP thermal profile, and Xilinx 4000XL family configuration architecture.
Technical Context
The XC4020XL-3PQ160I uses a hierarchical CLB-based architecture with configurable logic blocks, dedicated carry logic, and distributed RAM. It supports in-system programming via JTAG boundary-scan and accepts configuration bitstreams from external PROM or microcontroller.
It operates at 3.3 V core voltage with 5 V-tolerant I/Os, includes global clock buffers and three dedicated clock inputs, and implements IEEE 1149.1-compliant test access port for verification and debug.
