AT17C010-10CC

Overview

The AT17C010-10CC is a 1-Mbit (1,048,576 x 1-bit) serial EEPROM designed for FPGA configuration. It operates at 5V nominal with a supply range of 4.75V to 5.25V in commercial applications. The device supports a maximum clock frequency of 15 MHz and features a simple two-wire interface for reading configuration data. It includes a system-friendly READY pin to indicate power stability and allows programmable reset polarity. Available in 8-lead LAP, PDIP, and 20-lead PLCC packages.

Feature Summary

• Designed specifically as a configurator memory for Field Programmable Gate Arrays (FPGAs)
• Supports In-System Programming via a 2-wire serial bus
• Features a cascading architecture with Chip Enable Output for multi-device configurations
• Includes a READY pin to signal valid power levels during system startup

Applications

• Configuration of Xilinx XC3000, XC4000, and Spartan FPGAs
• Programming Altera FLEX and APEX devices
• Configuring Lucent ORCA and Atmel AT40K/AT94K FPGAs
• Emulation of legacy PROMs such as XC17 or ATT17

Procurement Notes

Verify the specific package variant required, as the base part number corresponds to multiple physical footprints including 8-lead LAP, PDIP, and 20-lead PLCC. Confirm that the 5V commercial grade specification aligns with the target operating temperature range of 0°C to 70°C. Ensure the design accounts for the open-collector nature of the READY pin if utilized.

Selection Notes

Select this component when a high-density serial memory solution is needed for SRAM-based FPGAs requiring master serial mode compatibility. Consider the AT17LV010 series if the system operates on a 3.3V supply instead of 5V. Evaluate the need for cascading capabilities if the single 1-Mbit capacity is insufficient for the target FPGA configuration size.

Part Context

This device belongs to the AT17 Series of FPGA Configuration EEPROMs, manufactured originally by Atmel and now under Microchip Technology. The series provides cost-effective, non-volatile storage for FPGA bitstreams. The AT17C010 represents the 1-Mbit density option within the standard 5V voltage family, offering pin compatibility across different package types within the same product line.

Replacement Considerations

The AT17LV010-10CC serves as the low-voltage equivalent for 3.3V systems. Legacy replacements include the AT24CXXX serial EEPROMs which are functionally emulated by this series. Direct substitutes for older configurations may include the AT17C512 for lower density requirements.
