Product details
Overview
XC4028XL-3HQ240C from Xilinx is a Field-Programmable Gate Array (FPGA) with 2,800 usable logic cells, 192 I/O pins, and a 3.3 V core voltage, configured in a 240-pin PQFP package for embedded control and digital signal processing applications.
For engineers reviewing the XC4028XL-3HQ240C datasheet, pinout, applications, or equivalent options, key selection criteria include logic density, I/O count, speed grade (-3), and QFP thermal and routing constraints in industrial control and communications interface designs.
Technical Context
The XC4028XL-3HQ240C implements a configurable logic block (CLB) architecture with four-input lookup tables (LUTs), dedicated carry logic for arithmetic, and distributed RAM capability per CLB. It supports synchronous design with global clock buffers and multiple clock enables.
Configuration is performed via JTAG boundary-scan or serial PROM, and it includes IEEE 1149.1-compliant test access. The device operates within an industrial temperature range (0°C to 70°C) and meets Xilinx's XL family low-power specifications.

FAQ
What is the maximum operating frequency supported by XC4028XL-3HQ240C?
The XC4028XL-3HQ240C has a -3 speed grade specifying a worst-case CLB propagation delay of 3.5 ns, supporting system clock frequencies exceeding 100 MHz in typical designs. Actual achievable frequency depends on logic depth, routing congestion, and I/O timing constraints. For guaranteed timing closure, static timing analysis using Xilinx Foundation or Alliance software is required for each XC4028XL-3HQ240C implementation.
Does XC4028XL-3HQ240C support in-system programming?
Yes, XC4028XL-3HQ240C supports in-system programming via its IEEE 1149.1 JTAG interface (TCK/TMS/TDI/TDO pins). Configuration can be reloaded dynamically through JTAG without power cycling, enabling field updates and debug workflows. The PROGRAM_B pin also allows hardware-triggered reconfiguration from external PROM, making XC4028XL-3HQ240C suitable for remote maintenance scenarios.
What are the power supply requirements for XC4028XL-3HQ240C?
XC4028XL-3HQ240C requires two separate 3.3 V supplies: VCCINT for the core logic (±0.3 V tolerance) and VCCO for I/O banks (also 3.3 V). Decoupling capacitors (100 nF ceramic + 10 µF tantalum per supply pair) must be placed near respective power pins. Total typical active current draw is 250 mA at 100 MHz toggle rate, with XC4028XL-3HQ240C exhibiting lower quiescent current than earlier XC4000E devices.
Is XC4028XL-3HQ240C pin-compatible with other XC4000XL devices in HQ240 package?
XC4028XL-3HQ240C shares the same 240-pin PQFP footprint and pinout with other XC4000XL family members in the HQ240 package (e.g., XC4013XL-3HQ240C, XC4020XL-3HQ240C), including identical power, ground, clock, and JTAG assignments. However, logic density and I/O count differ across variants, so functional compatibility requires design verification-not just pin matching-when substituting XC4028XL-3HQ240C.
What configuration modes does XC4028XL-3HQ240C support?
XC4028XL-3HQ240C supports master serial, slave serial, boundary-scan (JTAG), and peripheral mode configuration. In master serial mode, it drives an external PROM; in slave serial, it accepts configuration data from a microcontroller. JTAG mode enables programming and debugging without dedicated configuration hardware. All modes are implemented in hardware and require no firmware-XC4028XL-3HQ240C begins operation immediately after configuration completes.
