Product details
Overview
XC17128ELPC20C from AMD is a 128 kbit serial PROM configured for Xilinx FPGA configuration, operating at 5 V with 20 ns access time and industrial temperature range (–40°C to +85°C), used in legacy FPGA bitstream loading applications.
For engineers reviewing the XC17128ELPC20C datasheet, pinout, applications, or equivalent options, key considerations include voltage compatibility with older Xilinx devices, read-only nonvolatile storage timing, JEDEC-standard 20-pin DIP package footprint, and end-of-life supply chain status.
Technical Context
This device implements a CMOS-based serial EEPROM architecture optimized for synchronous bitstream loading into Xilinx XC4000-series FPGAs. It supports standard SPI-compatible serial read protocol with CE#, OE#, and WE# control lines, and requires no external programming voltage.
XC17128ELPC20C delivers deterministic 20 ns address-access timing under 5 V ±10% supply and operates across –40°C to +85°C without derating. Its internal organization is 16,384 × 8 bits, mapped to a single 128 kbit array with no page or sector erase functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 128 kbit (16,384 × 8) - fixed capacity for full XC4000-family bitstreams |
| Supply Voltage | 5.0 V ±10% - matches legacy Xilinx FPGA configuration voltage rails |
| Access Time | 20 ns - ensures timing compliance with XC4000-series CCLK setup/hold requirements |
| Operating Temp | –40°C to +85°C - qualified for industrial environment deployment |
| Interface | Serial CE#/OE#/WE# - asynchronous parallel-style control, not SPI bus protocol |
| Package | 20-pin plastic DIP (0.600") - direct fit into Xilinx reference PCB footprints |
Pinout & Package
XC17128ELPC20C is housed in a 20-pin plastic dual in-line package (PDIP) with 0.600-inch body width and 0.100-inch pin pitch. Pin functions are defined per Xilinx XC1700 family specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A13 | Address Inputs | 14-bit address bus selecting one of 16,384 bytes; tied low or decoded externally |
| I/O0–I/O7 | Data Outputs | 8-bit parallel data bus; outputs valid only when OE# = L and CE# = L |
| CE# | Chip Enable | Active-low enable controlling device selection; must be asserted before OE# for read access |
| OE# | Output Enable | Active-low gate for data bus; controls output driver state independent of CE# |
| WE# | Write Enable | Active-low input permanently tied high; device is factory-programmed, read-only |
| VCC, GND | Power Supply | Single 5 V supply; two dedicated pins for noise reduction in configuration path |
Key Features
| Feature | Design Value |
|---|---|
| Factory-programmed content | Preloaded with verified bitstream image; no field programming capability |
| JEDEC-standard 20-pin DIP | Drop-in replacement for XC17128LPC20C and compatible with Xilinx reference layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA configuration memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC17128LPC20C | Same 128 kbit size and 20 ns speed, but commercial temp range (0°C to +70°C) | Limited to controlled-environment lab or benchtop use; not rated for industrial ambient | Select only if operating temperature stays within 0–70°C and legacy stock is available |
| AT27C128A-20PU | 128 kbit EPROM, UV-erasable, requires 12.5 V VPP for programming, 25 ns access | Field-programmable but needs UV eraser and higher voltage; slower timing margin | Choose only when bitstream updates are required and infrastructure supports EPROM handling |
