Key Technical Features

Simple FPGA Interface

The XC17S30PC requires only one user I/O pin to interface with the Spartan device, minimizing design complexity and preserving valuable FPGA resources for your application logic.

Programmable Reset Polarity

The reset polarity (active High or active Low) is programmable, providing compatibility with different FPGA configurations and system designs.

Cascadable Architecture

Multiple PROMs can be cascaded to store longer or multiple bitstreams. The CEO (Chip Enable Output) pin drives the CE input of the next device in the chain, enabling configuration of larger FPGAs or multiple device systems.

Configuration Modes Supported

Pin Configuration

8-Pin Package (PDIP/VOIC) Pinout

20-Pin Package (PLCC/SOIC) Pinout

The 20-pin packages include additional VCC and GND pins for improved power distribution and noise immunity.

Application Guidelines

Power Supply Recommendations

• Connect all VCC pins together
• Use proper decoupling capacitors (0.1µF ceramic recommended)
• VPP must be connected to VCC during normal read operation
• Ensure monotonic power supply rise at power-up

Configuration Circuit Design

When designing with the XC17S30PC:

1. Connect PROM DATA output to FPGA DIN pin
2. Connect FPGA CCLK output to PROM CLK input (Master Serial mode)
3. Connect PROM OE/RESET to FPGA INIT pin with pull-up resistor
4. Drive PROM CE from FPGA DONE pin or tie Low

Product Status and Availability

The XC17S30 series is classified as a mature/obsolete product by AMD (formerly Xilinx). However, these devices remain available through authorized distributors and are still widely used in legacy systems and maintenance applications.
