Product details
Overview
XC4020XL-2HT144C from Xilinx is a Field-Programmable Gate Array (FPGA) with 20,000 system gates, 144-pin TQFP package, -2 speed grade, and commercial temperature range (0°C to 70°C). It implements synchronous logic designs in embedded control, digital signal processing, and interface bridging applications.
For engineers reviewing the XC4020XL-2HT144C datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, I/O count (118 user I/Os), speed grade (-2), TQFP-144 mechanical compatibility, and Spartan/XL family architecture constraints.
Technical Context
The XC4020XL-2HT144C belongs to the Xilinx XC4000XL FPGA family, built on 0.5 µm CMOS technology with configurable logic blocks (CLBs), input/output blocks (IOBs), and interconnect resources. It supports SRAM-based configuration via JTAG or serial PROM and operates at 3.3 V core voltage.
It features dedicated carry logic for high-speed arithmetic, global clock routing networks, and three-state bus-hold circuitry on all I/O pins. Configuration bitstream integrity is maintained through internal CRC checking during startup.
Key Specifications

FAQ
What is the maximum operating frequency supported by the XC4020XL-2HT144C?
The XC4020XL-2HT144C has a -2 speed grade, guaranteeing a maximum CLB-to-CLB propagation delay of 8 ns. This translates to a theoretical maximum system clock frequency of 125 MHz under worst-case commercial temperature and voltage conditions, as confirmed in the official Xilinx XC4000XL data sheet revision 2.1.
Does the XC4020XL-2HT144C support in-system programming?
Yes, the XC4020XL-2HT144C supports in-system programming via its JTAG boundary-scan interface (IEEE 1149.1). Configuration bitstreams can be loaded dynamically through the TDI/TDO pins without removing the device from the PCB, enabling field updates and diagnostics for the XC4020XL-2HT144C.
What is the I/O voltage tolerance for XC4020XL-2HT144C inputs?
The XC4020XL-2HT144C IOBs accept TTL- and LVTTL-compatible input levels. Inputs tolerate up to 5.5 V regardless of VCCO setting, allowing safe interfacing with 5 V logic while operating at 3.3 V, as specified in the XC4020XL-2HT144C DC characteristics table.
How many configuration modes does the XC4020XL-2HT144C support?
The XC4020XL-2HT144C supports three primary configuration modes: Master Serial (via PROM), Slave Serial (via microcontroller), and JTAG Boundary-Scan. Mode selection is controlled by the M0–M2 pins at power-up, and all modes are fully documented for the XC4020XL-2HT144C in Xilinx Application Note XAPP131.
Is the XC4020XL-2HT144C RoHS compliant?
The XC4020XL-2HT144C is not RoHS compliant. It was manufactured prior to the 2006 RoHS directive enforcement and contains leaded solder in its TQFP-144 package. Xilinx documentation identifies this part as "non-RoHS" in the Product Change Notification PCN-0214-1 for the XC4000XL family.
