AMD XC17S30VO8C

Overview

XC17S30VO8C from AMD is a serial configuration PROM designed for Xilinx Spartan-3 FPGAs, providing 3 Mbit storage capacity in an 8-pin SOIC package with 5V supply voltage and parallel read access. It supports fast configuration loading for FPGA boot-up in industrial control systems.

For engineers reviewing the XC17S30VO8C datasheet, pinout, applications, or equivalent options, key selection criteria include voltage compatibility (5V), serial configuration interface timing, data retention lifetime, programming endurance, and SOIC-8 mechanical fit in legacy FPGA carrier designs.

Technical Context

This PROM implements a synchronous serial interface compliant with Xilinx configuration protocol for Spartan-3 devices, using CE# and OE# active-low control signals. It features a 32-bit wide internal data register and supports both standard and fast read modes with tACC of 15 ns at VCC = 5.0V ±10%.

Internal architecture includes a CMOS EEPROM array with on-chip charge pump for write/erase operations, and built-in write protection via WP# pin. Data integrity is maintained through automatic page-write verification and end-of-write polling.

Key Specifications

Pinout & Package

XC17S30VO8C is housed in an 8-pin Small Outline Integrated Circuit (SOIC) package with 150-mil body width and standard gull-wing lead form. Pin assignments follow Xilinx-compatible PROM pinout convention for seamless integration into Spartan-3 configuration circuits.

XC17S30VO8C is available at Aetrix Electronics and suitable for industrial PLCs, legacy test equipment, and avionics ground support systems requiring stable component supply and long-lifecycle support.

Supply support for XC17S30VO8C includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

AMD acquired Xilinx in 2022 and now oversees legacy Xilinx programmable logic and configuration product lines, including the XC17 family of PROMs.

The XC17 series was originally developed by Xilinx to provide reliable, single-supply configuration memory for Spartan and Virtex FPGA families, targeting cost-sensitive industrial and communications infrastructure applications.

FAQ

Is XC17S30VO8C compatible with Xilinx Spartan-3A FPGAs?

Yes, XC17S30VO8C is fully compatible with Spartan-3A devices. Its 3 Mbit capacity, 5V operation, and Xilinx-standard serial configuration interface meet all timing and electrical requirements specified in DS099 and UG332 for Spartan-3A configuration. The XC17S30VO8C supports the same CCLK-driven read protocol and bitstream format used by Spartan-3A.

What is the maximum clock frequency supported during XC17S30VO8C read operations?

The XC17S30VO8C supports read operations up to 66 MHz, derived from its 15 ns access time specification at VCC = 5.0V. This aligns with the maximum CCLK frequency supported by Spartan-3 FPGAs during master serial configuration mode, ensuring no wait states are required when using XC17S30VO8C as the configuration source.

Can XC17S30VO8C be programmed in-system using standard Xilinx tools?

Yes, XC17S30VO8C can be programmed in-system via JTAG using Xilinx iMPACT or Vivado Hardware Manager with a compatible download cable. Programming requires the PROM file (.mcs) generated from the FPGA bitstream and adheres to Xilinx's IEEE 1149.1-compliant programming flow defined in UG332.

Does XC17S30VO8C require external pull-up resistors on control pins?

XC17S30VO8C requires external 4.7 kΩ pull-up resistors on CE# and OE# pins to ensure proper high-impedance state during FPGA configuration reset sequences. The WP# pin also requires a pull-up for default write protection; these values are specified in Xilinx Application Note XAPP114 for reliable operation across temperature and voltage ranges.

What is the programming voltage requirement for XC17S30VO8C?

XC17S30VO8C uses internal charge-pump circuitry and requires only a single 5.0V supply for both read and programming operations. No external high-voltage programming supply (e.g., 12V) is needed-unlike older EPROM-based PROMs-making it compatible with standard 5V PCB power distribution networks used in Spartan-3 carrier boards.
