Advanced Micro Devices, Inc. Configuration Proms for FPGAs XC18V256PC20I

The XC18V256PC20I is an in-system programmable configuration PROM designed for use with Xilinx FPGAs. It operates at a voltage of 3.3V and supports both serial and parallel configuration modes, with a maximum configuration speed of 33 MHz for serial and 264 Mb/s for parallel. The device features 256 Kbits of memory and is capable of enduring 20,000 program/erase cycles, making it suitable for applications requiring frequent reprogramming. This PROM is compatible with 5V, 3.3V, and 2.5V I/O signals, allowing for flexible integration into various systems. It supports JTAG command initiation for standard FPGA configuration and can be cascaded with other devices in the XC18V00 series or the XC17V00 one-time programmable family. The XC18V256PC20I is available in a 20-pin Plastic Leaded Chip Carrier (PLCC) package, making it a compact solution for FPGA configuration needs.
