AT17LV010A-10JU

Overview

The AT17LV010A-10JU is a 1-Mbit (131,072 x 1-bit) serial EEPROM designed for FPGA configuration. It supports 3.0V to 5.5V operation and operates within an industrial temperature range of -40°C to +85°C. The device features a maximum clock frequency of 10 MHz at 3.3V and 15 MHz at 5.0V, with access times as fast as 60 ns. Packaged in a 20-lead PLCC, it provides In-System Programmability via a 2-wire bus.

Feature Summary

• Designed specifically to store configuration programs for Altera FLEX and APEX Field Programmable Gate Arrays
• Supports both 3.3V and 5.0V operating voltage applications
• Enables In-System Programmability via a simple 2-wire bus interface
• Features programmable reset polarity and cascading capability for higher-density arrays

Applications

• Configuration memory for Altera FLEX and APEX FPGAs
• Configuration memory for Xilinx XC3000, XC4000, and Spartan devices
• Configuration memory for Atmel AT6000, AT40K, and AT94K devices
• Cascaded configurations for multiple FPGA setups

Procurement Notes

Verify the package type matches the required design footprint, as this specific model utilizes a 20-lead PLCC. Confirm that the industrial temperature rating (-40°C to +85°C) aligns with the operational environment requirements. Ensure programming equipment supports the 2-wire serial interface for In-System Programming capabilities.

Selection Notes

Select this component when a 1-Mbit capacity is required for SRAM-based FPGA initialization. It is suitable for designs needing compatibility with Altera or Xilinx architectures without external controllers. Consider the 20-lead PLCC package constraints and verify that the system supports the necessary 2-wire serial programming mode during development.

Part Context

This part belongs to the AT17LVxxxA family of FPGA configuration EEPROMs. These devices provide a cost-effective solution for loading configuration data into FPGAs automatically upon power-up. The family includes various densities, with the AT17LV010A offering 1-Mbit storage in a pin-compatible format alongside other members like the AT17LV512A and AT17LV002A.

Replacement Considerations

The AT17LV65A, AT17LV128A, and AT17LV256A are Not Recommended for New Designs and have been replaced by the AT17LV512A.
