AT17LV010-10PU

Overview

The AT17LV010-10PU is a 1-Mbit (1,048,576 x 1-bit) serial EEPROM designed for FPGA configuration. It operates within a supply voltage range of 3.0V to 5.5V and supports maximum clock frequencies up to 10 MHz at 3.3V and 12.5 MHz at 5.0V. The device utilizes an 8-lead PDIP package and features industrial temperature ratings from -40°C to +85°C. Key electrical characteristics include active mode current consumption of 5 mA at 3.3V and standby current of 100 µA.

Feature Summary

• Supports both 3.3V and 5.0V operating voltage applications
• Enables in-system programming via a 2-wire bus interface
• Provides cascadable read-back capability for higher-density arrays
• Features programmable reset polarity and write protection mechanisms

Applications

• Configuration memory storage for Field Programmable Gate Arrays (FPGAs)
• Master Serial Mode configuration for Xilinx XC3000, XC4000, and Spartan devices
• Cascaded configurations for multiple FPGAs or larger memory requirements

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's official documentation to ensure correct package type and voltage compatibility. Confirm that the component meets the required industrial temperature range specifications for your application environment. Cross-reference the datasheet revision history to ensure no design changes affect pinout or functionality.

Selection Notes

Select this component when a 1-Mbit capacity is required for SRAM-based FPGA configuration. Ensure the target FPGA supports Master Serial Mode for direct interfacing without external controllers. Verify that the system power supply remains within the specified 3.0V to 5.5V range to maintain reliable operation and data retention.

Part Context

This part belongs to the AT17LV series of FPGA Configuration EEPROMs manufactured by Microchip Technology (formerly Atmel). These configurators are specifically engineered to provide cost-effective and easy-to-use memory solutions for loading configuration programs into various FPGA families.

FAQ

How does the CEO pin function in a daisy-chain configuration?

The CEO output goes Low when the address counter reaches its maximum value. In a daisy chain, this signal drives the CE input of the next configurator, enabling its data output after the previous device finishes reading.

What is the purpose of the READY pin?

The READY pin is an open-collector indicator driven Low during the power-up reset cycle. It is released (tri-stated) when the power-up reset is complete, signaling that the device is ready for operation.
