XC18V01PC20C

Overview

The AMD XC18V01PC20C is a 1-megabit (128K x 8) configuration memory device designed for Xilinx Field Programmable Gate Arrays. It operates on a single 3.0 V to 3.6 V power supply, with a nominal voltage of 3.3 V. The component supports both parallel and serial programming modes, featuring an access time of 15 ns. It is housed in a 20-pin Plastic Quad Flat Package (PLCC) with a 1.27 mm pin pitch. The device functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports dual-mode operation allowing selection between parallel and serial programming interfaces for flexible integration.
• Utilizes CMOS technology to provide high-speed data access suitable for rapid FPGA configuration cycles.
• Designed as non-volatile EEPROM storage to retain configuration bitstreams without external power.

Applications

• Configuration of Xilinx Spartan-II and related FPGA families
• Industrial embedded systems requiring reliable boot-up sequences
• Test and measurement equipment needing reprogrammable logic states

Procurement Notes

Verify the specific suffix 'C' indicates the commercial/industrial temperature grade and package variant. Confirm that the source document explicitly lists this part number as active or available, as older configuration memories may be subject to end-of-life status. Ensure compatibility with the target FPGA's required configuration mode before procurement.

Selection Notes

Select this component when a 1-Mbit capacity is required for Xilinx FPGA initialization. Compare against the XC18V04 series if higher density is needed. Ensure the system design accommodates the 20-pin PLCC footprint and provides the necessary voltage regulation for the 3.3 V operating range.

Part Context

This part belongs to the XC18V00 series of PROMs specifically engineered for configuring Xilinx FPGAs. These devices serve as the primary storage medium for loading logic designs into the FPGA fabric upon power-up, replacing earlier mask-programmed options with user-reprogrammable flexibility.

Replacement Considerations

The XC18V01SC is a documented alternative offering identical 1-Mbit density and 20-pin PLCC packaging. Verify pinout compatibility and timing specifications against the XC18V01PC20C datasheet to ensure functional equivalence in the target application.
