AMD XC17128EVO8I

Overview

XC17128EVO8I from AMD is a 128-kbit serial configuration PROM designed for Xilinx FPGA initialization, featuring 5V operation, 150 ns access time, and industrial temperature range (–40°C to +85°C), used in embedded reconfigurable systems requiring nonvolatile bitstream storage.

For engineers reviewing the XC17128EVO8I datasheet, pinout, applications, or equivalent options, key selection criteria include voltage compatibility with Xilinx Virtex/E series FPGAs, read timing compliance, package footprint constraints, and industrial-grade reliability for field-deployed logic systems.

Technical Context

This PROM stores FPGA configuration bitstreams in serial mode and supports master serial configuration architecture. It uses CMOS technology with TTL-compatible inputs and outputs, and includes power-on reset circuitry to ensure deterministic startup behavior.

It operates exclusively from a 5V ±10% supply, requires no external programming voltage, and features a single active-low chip enable (CE#) and output enable (OE#) control scheme for system-level integration.

FAQ

What is the primary function of the XC17128EVO8I in FPGA-based systems?

The XC17128EVO8I serves as a serial configuration PROM that stores and delivers the bitstream to initialize Xilinx FPGAs such as the XC4000XL and Spartan families. It operates in master serial mode, driving the FPGA's DIN pin directly upon power-up. The XC17128EVO8I ensures deterministic, repeatable FPGA configuration without external programming hardware or JTAG intervention.

Does the XC17128EVO8I support 3.3V operation?

No, the XC17128EVO8I is specified for 5V ±10% operation only and is not compatible with 3.3V I/O systems. Its input thresholds and output drive levels are designed for TTL/5V CMOS logic families. Using it with 3.3V FPGAs requires level-shifting circuitry, which is not recommended. For 3.3V systems, consider alternatives like the XCF01SVO20C.

What package type does the XC17128EVO8I use, and is it RoHS compliant?

The XC17128EVO8I uses an 8-pin SOIC package (JEDEC MS-012AC outline) with gull-wing leads and 1.27 mm pitch. Per AMD documentation, this variant (suffix 'I') is industrial-grade and lead-free, meeting RoHS Directive 2011/65/EU requirements. No exemption codes apply, and Pb-free solder reflow profiles are validated per J-STD-020.

Can the XC17128EVO8I be reprogrammed in-system?

No, the XC17128EVO8I is a one-time programmable (OTP) PROM. It is programmed prior to system integration using dedicated PROM programmers such as the Xilinx Parallel Cable III or third-party devices supporting AMD XC17xx protocols. Once programmed, its contents cannot be altered in-circuit or via FPGA JTAG.

How does the XC17128EVO8I handle power-on reset sequencing with Xilinx FPGAs?

The XC17128EVO8I includes internal power-on reset circuitry that holds the DATA line inactive until VCC stabilizes within specification. This ensures clean bitstream delivery to the FPGA's DIN pin after power rail settling, preventing partial or corrupted configuration. The FPGA's INIT_B signal remains asserted until valid data begins flowing, synchronizing startup across both devices.
