AT17C512-10JI

Overview

The AT17C512-10JI is a 512-kilobit serial EEPROM designed for FPGA configuration. It operates at a nominal 5V supply voltage and supports an industrial temperature range of -40°C to +85°C. The device features a simple serial interface compatible with FPGA master modes, allowing direct connection without external controllers. It includes programmable reset polarity, write protection capabilities, and a system-friendly READY pin to indicate power stability during initialization.

Feature Summary

• Designed specifically for storing configuration programs for SRAM-based FPGAs
• Supports in-system programming via a 2-wire serial bus
• Features a cascading architecture for daisy-chaining multiple devices
• Includes a READY pin to signal valid power levels to the FPGA

Applications

• Configuration memory for Xilinx XC3000, XC4000, and Spartan FPGAs
• Configuration memory for Altera FLEX and APEX devices
• Configuration memory for Atmel AT40K and AT94K devices
• In-system programming of field programmable gate arrays

Procurement Notes

Verify that the specific ordering suffix corresponds to the required package type and operating temperature range. Confirm compatibility with the target FPGA's configuration mode requirements. Ensure the design accounts for the 5V nominal supply voltage specifications defined in the datasheet.

Selection Notes

Select this component when a non-volatile memory solution is required for FPGA configuration in industrial environments. It serves as a drop-in replacement for certain PROM devices. Consider the available packages, including PLCC, PDIP, and LAP, based on board space constraints.

Part Context

This part belongs to the AT17 Series of FPGA Configuration EEPROMs manufactured by Atmel (now Microchip Technology). The series provides cost-effective configuration memory solutions. The 'C' designation indicates standard 5V operation, distinguishing it from the LV variants which operate at 3.3V.
