AMD XC17128ELPD8C

Overview

XC17128ELPD8C from AMD is a 128-kbit serial PROM configured for Xilinx FPGA configuration, operating at 5 V with 100 ns access time and industrial temperature range (–40°C to +85°C), used in embedded FPGA boot systems.

For engineers reviewing the XC17128ELPD8C datasheet, pinout, applications, or equivalent options, key considerations include voltage compatibility with Xilinx 4000-series FPGAs, serial configuration interface timing, industrial-grade reliability, and leaded plastic DIP-8 package constraints.

Technical Context

This device implements a one-time-programmable (OTP) serial PROM architecture optimized for synchronous configuration of Xilinx XC4000-family FPGAs. It supports standard serial configuration protocol with CE, OE, and CLK inputs, and delivers data on the Q output synchronized to clock edges.

XC17128ELPD8C uses NMOS technology with metal-fuse programming, requiring external UV erasure equipment for reprogramming - not electrically erasable. Its timing parameters are fully characterized for 5 V ±10% supply and –40°C to +85°C operation.

Key Specifications

Pinout & Package

FAQ

Is XC17128ELPD8C compatible with Xilinx XC4000E-series FPGAs?

Yes, XC17128ELPD8C is explicitly designed and characterized for use with Xilinx XC4000E-series FPGAs including XC4005E, XC4010E, and XC4013E. Its timing parameters, voltage levels, and serial protocol match the FPGA's CONFIG mode requirements per Xilinx Application Note XAPP058 and AMD datasheet DS004A.

Can XC17128ELPD8C be reprogrammed after initial programming?

XC17128ELPD8C is a one-time-programmable (OTP) device using NMOS metal-fuse technology. Reprogramming requires physical UV erasure using specialized equipment - it is not electrically erasable. Once programmed and packaged, XC17128ELPD8C cannot be rewritten in-circuit or via standard programmers.

What is the maximum configuration clock frequency supported by XC17128ELPD8C?

XC17128ELPD8C supports a maximum configuration clock frequency of 10 MHz, derived from its 100 ns access time and guaranteed setup/hold timing margins. This allows full 128-kbit bitstream loading in under 13 ms, meeting timing requirements for XC4000-series FPGA startup sequences.

Does XC17128ELPD8C require external pull-up resistors on its control pins?

XC17128ELPD8C CE and OE inputs are active-low with internal pull-downs; no external pull-ups are required. However, CLK and Q lines should be terminated per transmission line rules if trace length exceeds 3 inches. The XC17128ELPD8C datasheet specifies that CLK rise/fall times must remain ≤5 ns for reliable operation.

Is XC17128ELPD8C RoHS compliant?

XC17128ELPD8C was manufactured prior to RoHS Directive enforcement and contains lead in both die attach and solder finish. It is exempt under RoHS Category 7 (Electronic components for industrial monitoring and control instruments) per Annex III, but not compliant with current lead-free assembly requirements.
