Overview
The XC18V01SO20I is a 3.3V in-system programmable configuration PROM from the XC18V00 series, housed in a 20-pin SOIC package. It provides 1 Megabit (1,048,576 bits) of non-volatile storage for Xilinx FPGA bitstreams. The device supports serial and parallel configuration modes with up to 33 MHz clock speeds. It features IEEE 1149.1 JTAG support for programming and boundary-scan testing, 5V tolerant I/O pins, and an endurance rating of 20,000 program/erase cycles.
Feature Summary
- In-system programmable via standard 4-pin JTAG protocol
- Supports cascading for storing longer or multiple bitstreams
- Dual configuration modes: Serial and Parallel
- Advanced data security against unauthorized reading
Applications
- Configuration of Virtex-II FPGAs
- Configuration of Spartan-IIE FPGAs
- Configuration of Virtex-E FPGAs
Procurement Notes
Verify the specific suffix 'SO20' confirms the 20-pin Small Outline Integrated Circuit package. Confirm the 'I' suffix indicates the industrial temperature range (-40°C to +85°C). Ensure compatibility with the target FPGA's voltage requirements and configuration mode settings before procurement.
Selection Notes
Select this component when a 1 Megabit capacity is required for FPGA configuration. Choose the SO20 package for space-constrained designs requiring surface-mount technology. Consider cascading with other XC18V00 devices if the target FPGA requires more than 1 Megabit of configuration data.
Part Context
The XC18V01SO20I belongs to the XC18V00 series of in-system programmable configuration PROMs. This family includes devices with capacities ranging from 512 Kilobit to 4 Megabit. These PROMs are designed specifically to store and provide configuration data to various Xilinx FPGA families, enabling reprogrammable hardware solutions.

FAQ
How is the CF pin function handled in the 20-pin package?
The 20-pin packages do not have a dedicated CF pin. The CF function can be routed to pin 7 by setting the CF --> D4 option, provided the parallel output mode is not used.
What is the maximum operating temperature for the XC18V01SO20I?
The device supports operation over the full commercial/industrial voltage and temperature range, with a maximum operating temperature of +85°C.
