XC17S15APD8I

Overview

The XC17S15APD8I is a serial one-time programmable (OTP) configuration PROM designed for Xilinx FPGA systems. It provides 512K-bit storage capacity organized as 512K x 1 bit. The device operates at a supply voltage of 3.3V and supports an industrial temperature range from -40°C to +85°C. It is housed in an 8-pin PDIP package, facilitating through-hole mounting on printed circuit boards for reliable hardware initialization.

Feature Summary

• Serial interface architecture optimized for sequential data retrieval during FPGA configuration cycles
• One-time programmable memory structure ensuring permanent retention of configuration bitstreams without power
• Industrial-grade thermal stability suitable for demanding operational environments

Applications

• Configuration of Xilinx Spartan-XL field-programmable gate arrays
• Hardware initialization in embedded industrial control systems
• Storage of boot code for dedicated digital logic applications

Procurement Notes

Verify the specific suffix 'A' indicates the 3.3V operating voltage variant distinct from standard 5V devices. Confirm the 'PD8I' designation corresponds to the 8-pin DIP industrial temperature grade. Ensure compatibility with the target FPGA's configuration mode requirements before procurement.

Selection Notes

Select this component when a 3.3V logic level is required for FPGA configuration rather than the traditional 5V standard. The serial interface reduces pin count compared to parallel alternatives. Verify that the 512K-bit density meets the specific bitstream size of the target design.

Part Context

This part belongs to the XC17S00 family of OTP PROMs manufactured by AMD/Xilinx. These devices are specifically engineered to store configuration data for Spartan and Spartan-XL FPGA families. They serve as non-volatile memory sources that initialize the FPGA fabric upon power-up.

Replacement Considerations

XC17S15PD8I: Verify if the system supports 5V operation, as this variant typically operates at 5V rather than 3.3V.
