Product details
Overview
XC4028XL-2HQ240C from Xilinx is a Field-Programmable Gate Array (FPGA) with 2,800 usable logic gates, 240-pin PQFP package, -2 speed grade, and designed for low-voltage 3.3V operation in embedded control and digital signal processing applications.
For engineers reviewing the XC4028XL-2HQ240C datasheet, pinout, applications, or equivalent options, key selection factors include I/O count (192 user I/Os), configuration mode (JTAG/Slave Serial), operating temperature range (0°C to 70°C), and compliance with IEEE 1149.1 JTAG boundary-scan standard.
Technical Context
The XC4028XL-2HQ240C implements a configurable logic block (CLB) architecture with dedicated carry logic for arithmetic functions and distributed RAM capability per CLB. It supports in-system programming via JTAG and uses SRAM-based configuration memory.
Configuration is performed through Slave Serial or JTAG modes, with support for automatic reconfiguration on power-up when used with external PROM. The device integrates global clock buffers and three dedicated clock input pins for synchronous design implementation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Gates | 2,800 usable gates - defines maximum combinational logic capacity for custom digital logic implementation |
| User I/O Pins | 192 - provides interface count for connecting to external peripherals, memory, or sensors |
| Package | 240-pin Plastic Quad Flat Pack (PQFP) - surface-mount, 32.5 mm × 32.5 mm footprint with 0.5 mm pitch |
| Supply Voltage | 3.3 V ± 0.3 V - requires single low-voltage rail; incompatible with 5 V TTL systems without level translation |
| Speed Grade | -2 - indicates 2 ns maximum carry chain delay; enables operation up to ~125 MHz system clock in typical designs |
| Operating Temperature | 0°C to +70°C - commercial-grade thermal rating suitable for office and non-industrial environments |
Pinout & Package
XC4028XL-2HQ240C is housed in a 240-pin PQFP (Plastic Quad Flat Pack) package with 0.5 mm lead pitch and 32.5 mm × 32.5 mm body size. Pin numbering follows standard counter-clockwise sequence starting from the index corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Multiple dedicated pins provide low-impedance return paths for core and I/O circuitry |
| VCCO | I/O power supply | Supplies 3.3 V to output drivers; separate from core VCCINT for noise isolation |
| VCCINT | Core logic power | Provides 3.3 V to internal CLBs and interconnect; must be decoupled locally |
| TCK/TMS/TDI/TDO | JTAG boundary-scan interface | Enables IEEE 1149.1-compliant testing, debugging, and in-system configuration |
| PROGRAM_B | Configuration reset | Active-low asynchronous input that clears configuration memory and initiates reload |
Key Features
| Feature | Design Value |
|---|---|
| SRAM-based configuration | Allows full reprogrammability in-system; configuration retained only while powered or with external PROM |
| Dedicated carry logic | Accelerates arithmetic operations (e.g., counters, adders) without consuming general-purpose CLBs |
| Three global clock inputs | Supports multi-domain synchronous design with low-skew clock distribution across the FPGA fabric |
| IEEE 1149.1 JTAG support | Enables boundary-scan testing, debug access, and standardized configuration loading |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA-based logic implementation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC4028XL-1HQ240C | Faster -1 speed grade (1.5 ns carry delay); otherwise identical logic capacity, I/O count, and package | Suitable where higher clock frequency or tighter timing margins are required | Select if design requires >125 MHz operation or reduced setup/hold slack |
| XC4036XL-2HQ240C | Higher logic density (3,600 gates); same package, voltage, and speed grade | Better suited for designs needing additional logic resources without board redesign | Choose when current XC4028XL-2HQ240C resource utilization exceeds 85% |
Compared with XC4028XL-2HQ240C, the -1 speed grade alternative enables higher-frequency operation within the same footprint, while the XC4036XL-2HQ240C offers headroom for logic expansion-both retain pin compatibility and configuration interface consistency.

FAQ
What is the configuration method supported by XC4028XL-2HQ240C?
The XC4028XL-2HQ240C supports Slave Serial and IEEE 1149.1 JTAG configuration modes. JTAG enables in-circuit programming and boundary-scan testing, while Slave Serial allows loading from external PROM. Configuration data is stored in volatile SRAM, requiring reload at power-up unless paired with nonvolatile memory.
Does XC4028XL-2HQ240C support hot-swapping or live insertion?
No, XC4028XL-2HQ240C does not support hot-swapping. Its 3.3 V supply and I/O structure require power to be stable before configuration and operation. Applying signal voltages before VCCINT and VCCO stabilization may cause latch-up or configuration corruption in the XC4028XL-2HQ240C.
What is the maximum operating frequency achievable with XC4028XL-2HQ240C?
The XC4028XL-2HQ240C has a -2 speed grade specifying 2 ns maximum carry chain delay. In typical synchronous designs with balanced routing, this supports system clock frequencies up to approximately 125 MHz. Actual performance depends on logic depth, placement, and routing in the implemented design.
Can XC4028XL-2HQ240C be used with 5 V tolerant I/Os?
No, XC4028XL-2HQ240C is a 3.3 V-only device. Its I/Os are not 5 V tolerant and exceed absolute maximum ratings if driven with 5 V signals. Level-shifting circuitry is required when interfacing with 5 V peripherals or buses in systems using the XC4028XL-2HQ240C.
Is there a migration path from XC4028XL-2HQ240C to newer Xilinx families?
While no direct pin-compatible upgrade exists, the Spartan-3E and Artix-7 families offer higher logic density, lower power, and enhanced features. Migration requires HDL redesign and PCB layout changes. Legacy support for XC4028XL-2HQ240C remains available through Aetrix Electronics' long-term obsolescence program.
