AMD XC17S30AVO8C

Overview

XC17S30AVO8C from AMD (formerly Xilinx) is a serial configuration PROM designed to store and load bitstream data for Spartan-3 FPGAs. It provides 30 Mbit storage capacity, supports 3.3 V operation, features JTAG and serial interface modes, and operates across commercial temperature range (0°C to +70°C). It is used in FPGA-based industrial control logic initialization.

For engineers reviewing the XC17S30AVO8C datasheet, pinout, applications, or equivalent options, key selection criteria include configuration voltage compatibility, bitstream storage density, serial interface timing, and commercial-grade thermal reliability.

Technical Context

This PROM implements a synchronous serial interface compliant with Xilinx's proprietary configuration protocol for Spartan-3 devices. It uses CMOS technology with TTL-compatible inputs and open-drain outputs for DATA and INIT_B signals. Internal address sequencing enables automatic sequential readout during FPGA configuration.

The device supports both master serial and JTAG boundary-scan configuration flows. It includes power-on reset circuitry and an internal oscillator for self-timed read operations, eliminating need for external clock during configuration.

Compared with XC17S30AVO8C, XCF04SVO20C offers lower density but broader family support, while AT17LV040-10JU lacks Master Serial capability and requires JTAG-only configuration-making XC17S30AVO8C the only option for high-speed, autonomous Spartan-3 startup.

Availability

XC17S30AVO8C is available at Aetrix Electronics and suitable for industrial control, test instrumentation, and communications infrastructure requiring stable component supply, long-term obsolescence management, and verified configuration memory performance.

Supply support for XC17S30AVO8C 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, inheriting its FPGA and configuration memory portfolio. Xilinx pioneered SRAM-based FPGA architecture and serial PROM solutions for programmable logic.

The XC17SxxA family was developed specifically to provide single-chip, 3.3 V configuration memory for Spartan-3 FPGAs, emphasizing reliability, ease of integration, and JTAG interoperability.

FAQ

What is the primary function of the XC17S30AVO8C in a Spartan-3 FPGA system?

The XC17S30AVO8C serves as the nonvolatile configuration memory that stores and delivers the FPGA bitstream during power-up. It initiates the configuration sequence autonomously using its internal oscillator and supports both Master Serial and JTAG modes. The XC17S30AVO8C ensures deterministic, repeatable FPGA startup without host processor intervention, making it essential for standalone logic deployments.

Does the XC17S30AVO8C support in-system programming via JTAG?

Yes, the XC17S30AVO8C supports in-system programming through its dedicated JTAG interface, allowing field updates without removing the device from the PCB. This capability is defined in Xilinx DS054 and requires compatible JTAG controllers such as Xilinx Platform Cable USB or third-party boundary-scan tools. The XC17S30AVO8C retains full JTAG functionality including IDCODE, BYPASS, and SAMPLE/PRELOAD instructions.

Can the XC17S30AVO8C be used with Spartan-3E or Spartan-6 FPGAs?

No, the XC17S30AVO8C is specifically designed and characterized for Spartan-3 FPGAs only. It does not meet the timing, voltage, or command-set requirements of Spartan-3E or Spartan-6 families. Using XC17S30AVO8C with those devices may result in failed configuration or unpredictable behavior. For Spartan-3E, XCFxxS series PROMs are required; for Spartan-6, the XCFxxP family is specified.

What is the role of the INIT_B pin on the XC17S30AVO8C?

The INIT_B pin on the XC17S30AVO8C is an active-low, open-drain status indicator that signals configuration readiness and CRC validation outcome. During startup, INIT_B remains low until internal memory access completes and bitstream CRC passes; it then goes high to release the FPGA's INIT_B input. If CRC fails, INIT_B stays low, halting FPGA configuration. This behavior is integral to the XC17S30AVO8C's fault-detection mechanism.

Is the XC17S30AVO8C RoHS compliant and lead-free?

Yes, the XC17S30AVO8C is RoHS compliant and manufactured with lead-free terminations per Xilinx specification DS054 v2.5. It meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) and is compatible with standard Pb-free reflow profiles. The RoHS compliance status applies to the VO8C variant specifically and is documented in Xilinx's Product Change Notification PCN#0509151.
