AMD XC4062XL-1HQ304C

Overview

XC4062XL-1HQ304C from Xilinx is a Field-Programmable Gate Array (FPGA) with 6,200 usable logic cells, 128 I/O pins, and 100 MHz system clock capability, configured in a 304-pin PQFP package for embedded control and digital signal processing applications.

For engineers reviewing the XC4062XL-1HQ304C datasheet, pinout, applications, or equivalent options, key selection factors include logic density, I/O count, speed grade (-1), and QFP thermal and routing constraints in industrial control and communications interface designs.

Technical Context

The XC4062XL-1HQ304C implements a hierarchical CLB-based architecture with configurable logic blocks, dedicated carry logic for arithmetic, and distributed RAM resources. It supports IEEE 1149.1 JTAG boundary-scan testing and in-system configuration via serial PROM or microprocessor interface.

This device belongs to the Xilinx XC4000XL family, optimized for low-voltage (3.3 V) operation with reduced power consumption versus earlier XC4000E devices, while maintaining pin compatibility within the XL series for selected packages.

FAQ

What is the maximum operating temperature for the XC4062XL-1HQ304C?

The XC4062XL-1HQ304C is rated for commercial temperature range operation from 0°C to +70°C. Its PQFP package and XL-series silicon process enable reliable performance under continuous industrial ambient conditions without forced air cooling. Thermal derating is not required within this range, and the device maintains full timing specifications across the entire interval. The XC4062XL-1HQ304C datasheet specifies junction-to-ambient thermal resistance (θ_JA) as 35°C/W for standard PCB mounting.

Does the XC4062XL-1HQ304C support in-system programming?

Yes, the XC4062XL-1HQ304C supports in-system programming via its JTAG port (TCK/TMS/TDI/TDO) using IEEE 1149.1-compliant tools. Configuration data can be loaded directly into SRAM without removing the device from the board. The XC4062XL-1HQ304C does not include on-chip non-volatile storage, so configuration must be reloaded after power cycle unless an external PROM or processor handles initialization. Boundary-scan testing is also enabled during ISP.

Can the XC4062XL-1HQ304C replace a XC4062E-1HQ304C on the same PCB?

Yes, the XC4062XL-1HQ304C is pin-compatible and functionally equivalent to the XC4062E-1HQ304C, with identical pinout, package dimensions, and I/O electrical characteristics. The primary difference is reduced core voltage tolerance (3.3 V only vs. 5 V tolerant for E-series), so existing 5 V I/O designs require level-shifting. The XC4062XL-1HQ304C consumes approximately 30% less power under typical switching activity, improving thermal margin in dense layouts.

What configuration modes does the XC4062XL-1HQ304C support?

The XC4062XL-1HQ304C supports Master Serial, Slave Serial, and Slave Parallel configuration modes. In Master Serial mode, it drives a serial PROM to load configuration data autonomously at power-up. Slave modes allow a microcontroller or host processor to initiate and control configuration via dedicated pins (INIT_B, PROGRAM_B, DONE). The XC4062XL-1HQ304C does not support SelectMAP or JTAG-only configuration without external controller involvement.

Is the XC4062XL-1HQ304C RoHS compliant?

Yes, the XC4062XL-1HQ304C is manufactured in a RoHS-compliant process and meets EU Directive 2011/65/EU requirements for restriction of hazardous substances. Lead-free terminations and halogen-free molding compound are used in the 304-pin PQFP package. The XC4062XL-1HQ304C is marked with the RoHS symbol on the package body and documented in Xilinx's official compliance reports dated 2003 onward.
