Overview

The AT17LV65-10SC is a Configurator EPROM used to configure Field Programmable Gate Arrays (FPGAs). It's an In-System Programmable (ISP) device from Atmel (now Microchip Technology). The 'LV' denotes low-voltage operation, and '-10SC' likely indicates the speed grade and package type (SC likely stands for small outline ceramic). It stores the configuration bitstream that defines the FPGA's functionality, loading it into the FPGA upon power-up or a reset.

Applications

• Configuration of Xilinx and Altera FPGAs.
• Storing configuration data for CPLDs.
• Embedded systems needing programmable logic.
• Industrial control systems.
• Aerospace applications (given the ceramic package).

Features

• 64-kilobit memory array (likely organized as 8K x 8).
• In-system programmable via serial interface.
• Low-voltage operation (typically 3.3V).
• Fast access time (10ns, as indicated by '-10').
• Low power consumption.
• Ceramic package for enhanced temperature performance.
• Serial data output.
• Non-volatile storage.

Benefits

• Non-volatile storage retains the FPGA configuration without power.
• In-system programmability simplifies configuration updates.
• Low-voltage operation reduces power requirements.
• Fast access time ensures quick FPGA configuration at startup.
• Ceramic package provides better thermal performance and reliability in harsh environments.

Additional Details

The AT17LV65-10SC communicates serially to the FPGA. In-system programming allows updating the configuration data without physically removing the device from the board. The low-voltage operation caters to modern FPGA designs. The '10' in the part number suggests a 10ns access time, contributing to fast configuration. The ceramic package enhances robustness and allows it to function in extended temperature ranges compared to plastic packages. It is typically programmed using a JTAG interface or a dedicated programmer. Specific information relating to timing characteristics, voltage ranges and tolerance, package dimensions, and operating temperature will be located in the device datasheet.
