AT17LV002-10CU

Overview

The AT17LV002-10CU is a 2-Mbit 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 up to 15 MHz at 5.0V. It utilizes a simple serial interface compatible with SRAM FPGAs in Master Serial mode. The component is housed in an 8-lead Leadless Array Package (LAP) with CuNiAu lead finish.

Feature Summary

• Supports In-System Programming via a 2-wire bus
• Features cascading capability through the Chip Enable Output pin
• Allows programmable reset polarity during programming
• Includes write protection mechanisms within programming mode

Applications

• Configuration memory for Xilinx Spartan and Virtex FPGAs
• Configuration memory for Altera FLEX and APEX devices
• Configuration memory for Atmel AT6000, AT40K, and AT94K devices
• Cascaded configuration arrays for high-density FPGA systems

Procurement Notes

Verify that the ordering suffix 'CU' corresponds to the 8-lead LAP package with CuNiAu finish as specified in the official Microchip ordering guide. Confirm the device density matches the 2-Mbit specification for the AT17LV002 family. Ensure compatibility with the target FPGA's master serial configuration requirements before procurement.

Selection Notes

Select this component when a 2-Mbit capacity is required for FPGA configuration. The 8-lead LAP package offers a compact footprint suitable for space-constrained designs. Verify that the system voltage falls within the 3.0V to 5.5V operating range. Consider the industrial temperature rating if the application environment exceeds standard commercial limits.

Part Context

This part belongs to the AT17LV series of FPGA Configuration EEPROMs manufactured by Microchip Technology. The series provides non-volatile storage for configuration data used by various SRAM-based FPGAs. The AT17LV002 specifically offers 2-Mbit density, distinguishing it from smaller variants like the AT17LV256 or larger ones like the AT17LV040.

Replacement Considerations

AT17LV002-10JU: Same electrical specifications but packaged in a 20-lead PLCC with Sn finish. AT17LV002-10SU: Same electrical specifications but packaged in a 20-lead SOIC with Sn finish. AT17LV002-10TQU: Same electrical specifications but packaged in a 44-lead TQFP with Sn finish.
