AT17LV010A-10JI

Overview

The AT17LV010A-10JI is a 1-Mbit (1,048,576-bit) serial EEPROM configurator designed for FPGA configuration. It operates at 3.3V or 5.0V with an industrial temperature range of -40°C to +85°C. The device supports in-system programming via a 2-wire bus and features a maximum clock frequency of 10 MHz. It provides high reliability with 100,000 write cycles and 90-year data retention. Available in a 32-lead TQFP package, it interfaces directly with SRAM FPGAs.

Feature Summary

• Supports In-System Programming (ISP) via a simple 2-wire serial bus interface
• Enables cascading read-back capabilities to support additional configurations or higher-density arrays
• Allows user-programmable reset polarity through four EEPROM bytes
• Features low-power standby mode and high-reliability endurance specifications

Applications

• Configuration memory for Altera FLEX and APEX FPGAs
• Configuration storage for Xilinx XC3000, XC4000, XC5200, Spartan, and Virtex FPGAs
• Configuration memory for Lucent ORCA and Motorola MPA1000 FPGAs

Procurement Notes

Verify the specific ordering suffix 'JI' confirms the industrial temperature grade (-40°C to +85°C) and 3.3V/5.0V operation. Confirm the 32-lead TQFP package type matches the design requirements. Ensure compatibility with the target FPGA's master serial mode and voltage levels before procurement.

Selection Notes

Select this component when a 1-Mbit capacity is required for FPGA configuration. Choose the industrial grade variant for environments requiring operation between -40°C and +85°C. Consider the 32-lead TQFP package if space constraints or pin count necessitate this form factor over PLCC or PDIP options.

Part Context

This part belongs to the AT17A series of FPGA configuration EEPROMs. These devices are designed to provide cost-effective configuration memory for Field Programmable Gate Arrays. The series includes various densities ranging from 64-Kbit to 2-Mbit, all sharing pin-compatible packages across the family for design flexibility.

FAQ

How is the reset polarity configured?

The polarity of the RESET/OE pin can be programmed by the user using four specific EEPROM bytes during the programming process.

What is the function of the nCASC pin?

The nCASC pin is a cascade select output that goes Low when the address counter reaches its maximum value, allowing daisy-chaining of multiple configurators.
