AT17LV65-10SI

Configuration PROMs For FPGAs Overview

The AT17LV65-10SI is a serial EEPROM designed for FPGA configuration, offering 64-Kbit capacity. It supports 3.3V and 5.0V applications with an operating voltage range of 3.0V to 3.6V at commercial temperatures (0°C to +70°C) and 3.0V to 5.5V at industrial temperatures (-40°C to +85°C). The device features in-system programmability via a two-wire bus and interfaces directly with SRAM FPGAs using a simple serial access procedure.

Configuration PROMs For FPGAs Feature Summary

• Supports In-System Programmability (ISP) via a Two-Wire Bus
• Provides direct interface compatibility with SRAM-based FPGAs
• Features low-power CMOS EEPROM process technology
• Allows user-programmable reset polarity settings

Configuration PROMs For FPGAs Applications

• Configuration memory for Field Programmable Gate Arrays (FPGAs)
• Storage of configuration programs for Altera FLEX and APEX devices
• Configuration storage for Xilinx XC3000, XC4000, and Spartan devices
• Setup for Atmel AT40K and AT94K series devices

Configuration PROMs For FPGAs Procurement Notes

Verify the specific package suffix 'SI' corresponds to the 20-lead SOIC format as defined in the ordering information tables. Confirm that the required temperature grade matches the Industrial specification (-40°C to +85°C), as the SI suffix indicates this range. Ensure the design accounts for the absence of the CEO cascading feature on the AT17LV65 model when planning multi-device configurations.

Configuration PROMs For FPGAs Selection Notes

Select this component for designs requiring 64-Kbit non-volatile storage for FPGA initialization. It is suitable for systems needing dual voltage support (3.3V/5V) and direct FPGA interfacing without external controllers. Note that the AT17LV65 lacks the CEO pin required for daisy-chaining multiple configurators, limiting its use to single-device or parallel setups.
