AT17LV002-10SC

Overview

The AT17LV002-10SC is a 2-Mbit serial EEPROM designed for FPGA configuration. It operates at supply voltages of 3.3V or 5.0V and supports industrial temperature ranges from -40°C to +85°C. The device utilizes a simple two-wire serial interface for in-system programming and direct connection to SRAM-based FPGAs. It features programmable reset polarity, write protection mechanisms, and cascading capabilities via the CEO output pin. The component is housed in a 20-lead Plastic Gull Wing Small Outline (SOIC) package.

Feature Summary

• Supports both 3.3V and 5.0V operating voltage applications
• Enables in-system programming via a two-wire bus interface
• Allows user-programmable reset polarity settings
• Provides cascading read-back support for higher-density arrays

Applications

• Configuration memory storage for Field Programmable Gate Arrays
• In-system programming of FPGA configuration data
• Cascaded configurations for multiple FPGA devices

Procurement Notes

Verify that the ordering suffix 'SC' corresponds specifically to the 20-lead SOIC package variant. Confirm the industrial temperature grade (-40°C to +85°C) matches system requirements. Ensure compatibility with the specific FPGA model's master serial mode timing constraints before procurement.

Selection Notes

Select this part when a 2-Mbit capacity is required for FPGA configuration. The 20-lead SOIC package is suitable for surface-mount assembly where space allows. Verify that the target FPGA supports the serial configuration protocol and that the available supply voltage aligns with the device's 3.3V or 5.0V operation modes.
