Product details
Overview
XC4020XL-3PQ208C from Xilinx is a Field-Programmable Gate Array (FPGA) with 20,000 system gates, 208-pin Plastic Quad Flat Package (PQFP), -3 speed grade (3.5 ns CLB propagation delay), and commercial temperature range (0°C to 70°C). It targets mid-complexity digital logic implementation in industrial control, communications interface bridging, and embedded system acceleration.
For engineers reviewing the XC4020XL-3PQ208C datasheet, pinout, applications, or equivalent options, key selection criteria include CLB count, I/O pin count, speed grade timing compliance, and configuration mode support (e.g., master serial, slave parallel).
Technical Context
The XC4020XL-3PQ208C implements configurable logic blocks (CLBs) arranged in a symmetrical array, each containing two 3-input look-up tables (LUTs) and flip-flops. It supports synchronous and asynchronous reset, clock enable, and three global clock networks.
Configuration is performed via serial PROM or parallel mode using dedicated CONFIG pins. The device uses SRAM-based configuration memory and requires external configuration on power-up. It supports IEEE 1149.1 JTAG boundary-scan testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Capacity | 20,000 usable system gates - defines maximum combinational logic density for custom digital functions |
| Configurable Logic Blocks (CLBs) | 576 CLBs - each provides dual 3-LUTs + flip-flop, enabling efficient register-rich or logic-dense mapping |
| I/O Pins | 160 user I/O pins - supports wide parallel buses, multi-protocol interfaces, and high-pin-count peripheral interfacing |
| Speed Grade | -3 (3.5 ns CLB tPD) - guarantees worst-case signal propagation delay through a single CLB at commercial temperature |
| Package | PQ208 - 208-pin plastic quad flat pack, 0.5 mm pitch, surface-mount compatible with standard reflow profiles |
| Operating Temperature | 0°C to +70°C - validated for commercial-grade environments without extended thermal derating |
Pinout & Package

FAQ
What is the configuration method supported by XC4020XL-3PQ208C?
The XC4020XL-3PQ208C supports master serial, slave serial, and slave parallel configuration modes. Master serial uses an external PROM connected to DIN and CCLK; slave modes accept configuration data from a microcontroller or host processor. All modes rely on SRAM-based bitstream loading at power-up.
Does XC4020XL-3PQ208C support JTAG boundary-scan?
Yes, XC4020XL-3PQ208C includes full IEEE 1149.1 JTAG support via TCK, TMS, TDI, and TDO pins. This enables in-system programming, configuration verification, and interconnect testing without requiring dedicated test fixtures or physical probe access.
What is the maximum operating frequency for CLB logic in XC4020XL-3PQ208C?
The XC4020XL-3PQ208C has a -3 speed grade specifying 3.5 ns CLB propagation delay (tPD). This translates to a theoretical maximum toggle rate of approximately 143 MHz for a single CLB path under commercial conditions, though actual system frequency depends on routing, fanout, and logic depth.
Can XC4020XL-3PQ208C be used in automotive applications?
No, XC4020XL-3PQ208C is rated for commercial temperature range (0°C to +70°C) only and lacks AEC-Q100 qualification, automotive-grade screening, or extended temperature support. It is not recommended for under-hood or safety-critical automotive systems.
Is XC4020XL-3PQ208C pin-compatible with other XC4000XL devices in PQ208 package?
Yes, all XC4000XL family members in the PQ208 package-including XC4013XL-3PQ208C, XC4020XL-3PQ208C, and XC4025XL-3PQ208C-share identical pinouts and electrical characteristics. This allows direct substitution within the same speed grade and configuration mode.
