AT17C512-10CI

Overview

The AT17C512-10CI is a 512-kilobit serial EEPROM designed for FPGA configuration. It operates at 5V nominal with an industrial temperature range of -40°C to +85°C. The device supports In-System Programming via a 2-wire bus and features a simple serial interface compatible with SRAM FPGAs. It includes a system-friendly READY pin, programmable reset polarity, and low-power standby mode.

Feature Summary

• Designed to store configuration programs for Field Programmable Gate Arrays (FPGAs)
• Supports In-System Programming via a 2-wire bus
• Features a system-friendly READY pin indicating good power levels
• Allows user-programmable reset polarity

Applications

• Configuration memory for Xilinx XC3000, XC4000, XC5200, Spartan, and Virtex FPGAs
• Configuration memory for Altera FLEX and APEX devices
• Configuration memory for Atmel AT6000, AT40K, and AT94K devices
• Configuration memory for Lucent ORCA FPGAs

Procurement Notes

Verify the specific ordering suffix 'CI' corresponds to the Industrial temperature range (-40°C to +85°C) and 5V supply voltage. Confirm package availability matches the required form factor, as this part number family supports LAP, PDIP, and PLCC packages. Ensure compatibility with existing FPGA master serial mode requirements before procurement.

Selection Notes

Select this component when a 512-kilobit non-volatile memory solution is required for configuring SRAM-based FPGAs in industrial environments. It serves as a drop-in replacement for legacy PROMs like the XC17/ATT17 series. Consider cascading capabilities if larger configuration memories are needed for multiple or high-density FPGA arrays.

Part Context

This device belongs to the AT17 Series Configurators, which provide cost-effective configuration memory for FPGAs. The series includes both 5V (AT17C) and 3.3V (AT17LV) variants with capacities of 512-kbit and 1-megabit. The AT17C512-10CI specifically denotes the 5V, 512-kbit version intended for industrial temperature applications.

Replacement Considerations

Publicly confirmed substitutes include AT17C512-10CC (Commercial temperature), AT17C512-10PC (PDIP package), and AT17C512-10JC (PLCC package). These parts share identical electrical and functional specifications but differ in operating temperature range or physical package type.
