XC18V256SO20C Description

Short technical summary and product information.

The Xilinx XC18V256SO20C is an in-system programmable configuration PROM (CPLD) designed for Xilinx FPGAs. This 3.3V device offers a memory size of 256Kbit, providing a cost-effective solution for storing and re-programming FPGA configuration bitstreams.

 

Key features include dual configuration modes: Serial Slow/Fast configuration up to 33 MHz and Parallel configuration up to 264 Mb/s at 33 MHz. The PROM supports IEEE Std 1149.1 boundary-scan (JTAG) and offers a simple interface to the FPGA. It is cascadable for storing longer or multiple bitstreams.

 

The XC18V256SO20C is available in a 20-pin SOIC package, suitable for surface mounting. It operates over a commercial temperature range of 0°C to 70°C and has an endurance of 20,000 program/erase cycles. The device features 5V tolerant I/O pins and 3.3V or 2.5V output capability.
