XC4062XLA-9HQ240C Architecture and Features
H2: XC4000XLA Family Architecture Overview
The XC4000XLA family was Xilinx’s high-performance 3.3V generation designed to bridge the gap between earlier 5V FPGAs and the emerging low-voltage Virtex line. The XC4062XLA-9HQ240C inherits a robust architectural foundation with the following key elements:
Configurable Logic Blocks (CLBs): Each CLB in the XC4000XLA architecture contains two function generators (F and G), carry logic, and flip-flops. The 2,304 CLBs in the XC4062XLA-9HQ240C provide substantial logic density for complex combinational and sequential designs.
Dedicated Carry Logic: Hardened fast-carry chains enable efficient arithmetic operations such as adders, counters, and accumulators without consuming additional routing resources.
Distributed RAM: The function generators within each CLB can be configured as 16×1 synchronous RAM, enabling efficient on-chip data storage for FIFOs, buffers, and lookup tables.
Global Clocking: Four global clock buffers with low-skew routing networks support multi-clock domain designs. The device supports Delay-Locked Loops (DLLs) for clock deskewing and frequency synthesis.
Boundary Scan (JTAG): Full IEEE 1149.1 JTAG support is included for in-circuit testing, debugging, and configuration via the JTAG interface.

H3: EDA & PCB Design Considerations
- PCB Footprint: The HSPQFP-240 package requires a 0.5 mm or 0.65 mm pitch QFP land pattern. Verify the specific pitch (0.5 mm typical for HQ240) against the package specification before board layout.
- Decoupling Capacitors: Place 100 nF ceramic decoupling capacitors within 2–3 mm of each VCC pin to minimize power supply noise.
- Configuration Pull-Up Resistors: PROGRAM, INIT, and DONE pins typically require external pull-up resistors (4.7 kΩ to 10 kΩ) depending on the configuration mode.
- JTAG Chain: The XC4062XLA-9HQ240C supports standard 4-wire JTAG (TCK, TMS, TDI, TDO). It can be daisy-chained with other JTAG-compliant devices.
Frequently Asked Questions
H3: Is the XC4062XLA-9HQ240C still in production?
No. The XC4062XLA-9HQ240C is an End-of-Life (EOL) component. Xilinx (AMD) discontinued production of the XC4000XLA family as the design community migrated to Spartan, Virtex, and later 7-Series FPGAs. The device remains widely available through authorized distributors and specialty component sourcing companies that stock legacy semiconductors.
H3: What is the difference between XC4062XLA-9HQ240C and XC4062XLA-09HQ240C?
These two part numbers refer to identical devices. The only difference is notational — some databases and distributors omit the leading zero in the speed grade, writing “-9” instead of “-09.” Both designations describe the same Xilinx XC4000XLA FPGA with a -9 speed grade, 240-pin HSPQFP package, and commercial temperature range.
H3: Can I replace the XC4062XLA-9HQ240C with a newer FPGA?
A direct pin-compatible drop-in replacement does not exist in current Xilinx (AMD) product lines because the HQ240 HSPQFP package was discontinued along with the XC4000XLA family. If a board redesign is feasible, functional migration to a Spartan-6 or Artix-7 family FPGA with a re-routed PCB is the recommended path forward.
H3: What design tools support the XC4062XLA-9HQ240C?
The XC4062XLA-9HQ240C is supported by legacy Xilinx Foundation Series and ISE Design Suite software (ISE 14.7 being the final version). Vivado, Xilinx’s current design suite, does not support the XC4000XLA family.
Summary
The XC4062XLA-9HQ240C is a 62,000-gate, 3.3V FPGA from Xilinx’s proven XC4000XLA family, packaged in a 240-pin HSPQFP. With 2,304 CLBs, 5,472 logic cells, and a maximum operating frequency of 227 MHz, it delivers reliable programmable logic performance for industrial, communications, and legacy embedded system designs. While now classified as an End-of-Life component, it remains an important part in maintenance and life-extension programs across numerous industries.
For design engineers sourcing this device or evaluating compatible alternatives, always confirm the exact part number suffix — particularly the speed grade (-9), package code (HQ240), and temperature grade (C for commercial) — to ensure proper fit for your application.
