AMD XC17128EVOG8C

Overview

XC17128EVOG8C from AMD is a 128-kbit serial PROM configured for Xilinx FPGA configuration, operating at 5V supply voltage with 150 ns maximum access time and industrial temperature range (–40°C to +85°C), used in legacy FPGA bitstream storage and system boot initialization.

For engineers reviewing the XC17128EVOG8C datasheet, pinout, applications, or equivalent options, key selection criteria include VCC compatibility, read access timing, JEDEC-standard SOIC-8 footprint, and FPGA configuration interface support.

Technical Context

This device implements a CMOS-based serial EEPROM architecture optimized for Xilinx 4000-series FPGA configuration, supporting standard SPI-compatible serial read protocol with single-byte addressing and no write capability in production operation.

It features internal address auto-increment during sequential reads, fixed 128 kbit (16K × 8) organization, and requires external pull-up on DATA output line per Xilinx configuration specification.

Key Specifications

Pinout & Package

XC17128EVOG8C is housed in an 8-pin SOIC package (JEDEC MS-012AA, 150-mil width, 1.27 mm pitch) with gull-wing leads and standard thermal profile compatibility.

FAQ

Is XC17128EVOG8C programmable in the field?

No, XC17128EVOG8C is factory-programmed and read-only. It contains a fixed bitstream image and lacks internal erase or write circuitry. Any change to stored configuration requires replacing the XC17128EVOG8C with a newly programmed unit. This design ensures immunity to accidental corruption during system operation.

What is the maximum clock frequency supported by XC17128EVOG8C?

XC17128EVOG8C supports a maximum serial clock (CLK) frequency of 6.67 MHz, derived from its 150 ns access time specification. This aligns with the timing requirements of Xilinx XC4000-series FPGAs during master-mode configuration. Exceeding this frequency may result in invalid DATA output sampling.

Does XC17128EVOG8C require external pull-up resistors?

Yes, XC17128EVOG8C requires an external 4.7 kΩ pull-up resistor on the DATA pin to VCC. The DATA output is open-drain, and proper signal integrity during configuration depends on this pull-up. Missing or incorrect resistor value can cause configuration failure or intermittent startup behavior.

Can XC17128EVOG8C be used with modern Xilinx FPGA families like Artix or Kintex?

No, XC17128EVOG8C is not compatible with Artix, Kintex, or other post-4000-series Xilinx FPGAs. Its timing, voltage, and protocol are specific to XC4000-family configuration engines. Modern devices require different PROM types such as XCFxx or SPI flash with dedicated controller logic.

What is the meaning of "EVOG8C" in XC17128EVOG8C?

"EVOG8C" denotes the package and temperature grade: "EV" indicates commercial/industrial grade, "OG8" specifies SOIC-8 package (JEDEC MS-012AA), and "C" confirms lead-free (Pb-free) construction compliant with RoHS Directive 2011/65/EU. This suffix distinguishes it from obsolete leaded variants.
