AT17LV040-10TQI

Configuration PROMs For FPGAs Overview

The AT17LV040-10TQI is a 4-Mbit (4,194,304-bit) serial EEPROM designed for FPGA configuration. It operates at 3.3V or 5.0V and supports In-System Programming via a Two-Wire Bus. The device features a simple serial interface compatible with SRAM FPGAs, including Xilinx and Altera devices. It offers high reliability with 100,000 write cycles and data retention up to 190 years. The component is housed in a 44-lead Thin Plastic Quad Flat Package (TQFP) and supports cascading for higher-density arrays.

Configuration PROMs For FPGAs Procurement Notes

Verify the specific package type and temperature range against the datasheet ordering codes. Confirm that the 'TQ' suffix corresponds to the 44-lead TQFP package and the 'I' suffix indicates the industrial temperature range (-40°C to +85°C). Ensure compatibility with the target FPGA's master serial mode requirements before procurement.

Configuration PROMs For FPGAs Selection Notes

Select this component when a 4-Mbit capacity is required for FPGA configuration. It is suitable for designs needing support for both 3.3V and 5.0V systems. Consider its compatibility with specific FPGA families like Xilinx and Altera. Verify if the 44-lead TQFP package fits the board layout constraints. Check if cascading capabilities are needed for larger configurations.

Configuration PROMs For FPGAs Part Context

The AT17LV series consists of serial EEPROM configurators designed specifically for SRAM-based FPGAs. This family includes various densities from 65K-bit to 4M-bit. The AT17LV040 represents the highest density option in this specific series, providing substantial storage for complex FPGA bitstreams. It is part of Microchip's (formerly Atmel) portfolio of configuration memories.
