AT17C512-10CC

Overview

The AT17C512-10CC is a 512-kilobit serial EEPROM designed for FPGA configuration. It operates at a nominal 5V supply voltage and supports a maximum input clock frequency of 15 MHz in commercial applications. The device provides 524,288 bits of non-volatile storage organized as 524,288 x 1-bit words. It features a simple serial interface compatible with FPGA master serial modes and includes a system-friendly READY pin to indicate power-up completion. The component is available in an 8-lead Leadless Array Package (LAP) suitable for commercial temperature ranges.

Feature Summary

• Designed specifically for storing configuration programs for Field Programmable Gate Arrays (FPGAs)
• Supports In-System Programming via a 2-wire bus and cascading read-back capabilities
• Includes a programmable reset polarity feature and a low-power standby mode
• Features a system-friendly READY pin that indicates valid power levels during startup

Applications

• Configuration memory for Xilinx XC3000, XC4000, and Spartan FPGAs
• Programming Altera FLEX and APEX devices
• Configuration for Atmel AT40K and AT94K series devices
• Daisy-chain configurations requiring multiple configurators for higher-density arrays

Procurement Notes

Verify the specific package type required, as the AT17C512-10CC designation corresponds to the 8-lead LAP package. Confirm that the application environment remains within the commercial operating temperature range of 0°C to 70°C. Ensure the design utilizes a 5V ± 5% or ± 10% supply rail, as this part is not rated for 3.3V operation. Check for updated manufacturer documentation regarding legacy Atmel product transitions.

Selection Notes

Select this component when a dedicated FPGA configurator is needed rather than a general-purpose data EEPROM. It is suitable for designs requiring direct interfacing with FPGA control signals like CCLK and CE without external controllers. Consider the 8-lead LAP package if space constraints exist, noting its pin compatibility with other 8-lead packages in the family. Verify that the target FPGA supports the master serial configuration mode.

Part Context

This device belongs to the AT17 Series of high-density FPGA Configuration EEPROMs, also known as Configurators. The series includes variants such as the AT17LV512 for lower voltage operations and the AT17C010 for 1-megabit capacity. These devices emulate older Atmel PROMs and provide a cost-effective solution for programming SRAM-based FPGAs upon power-up.

Replacement Considerations

The AT17LV512-10CC serves as a low-voltage alternative within the same package footprint. For legacy replacements, check compatibility with Atmel AT6000, AT40K, and AT94K device families. Verify electrical compatibility with Xilinx XC17/ATT17 PROM equivalents if migrating from older designs.
