Overview

The AT17LV65 is a Configurator, specifically an In-System Programmable Configuration EPROM (Configurator) designed to configure Field Programmable Gate Arrays (FPGAs) from Atmel (now Microchip Technology). The 'LV' likely stands for Low Voltage. It stores the bitstream that defines the logic implemented within the FPGA. Upon power-up or a reset signal, the AT17LV65 loads this configuration data into the FPGA.

Applications

• Configuration of Xilinx and Altera FPGAs.
• Storing configuration data for CPLDs.
• Boot-up code storage for embedded systems.
• Industrial control systems requiring configurable logic.
• Telecommunications equipment utilizing FPGAs.

Features

• 64-kilobit memory array (likely organized as 8K x 8).
• In-system programmable.
• Low-voltage operation (typically 3.3V).
• Serial data output.
• Fast access time.
• Low power consumption.
• Compact package options.

Benefits

• Non-volatile storage: retains configuration data without power.
• In-system programmability: allows configuration updates without removing the device.
• Low-voltage operation: simplifies power supply design.
• Fast access time: ensures quick FPGA configuration at startup.
• Reduced board space: compact package options minimize footprint.

Additional Details

The AT17LV65 uses a serial interface to transfer configuration data to the FPGA. It's typically programmed using a JTAG interface or a dedicated programmer. The low-voltage operation is crucial for modern FPGA designs that operate at lower voltages. The speed grade determines the maximum clock frequency for the serial interface, impacting the FPGA configuration time. Different package options cater to varying board layout requirements. The data sheet will have timing, voltage ranges and package types and the specific FPGAs it supports.
