AT17LV512-10JU

Configuration PROMs For FPGAs Overview

The AT17LV512-10JU is a 512-kbit serial EEPROM designed for FPGA configuration. It operates on 3.0V to 5.5V supplies and supports industrial temperatures from -40°C to +85°C. The device uses a simple serial interface with a maximum clock frequency of 10 MHz at 3.3V and 12.5 MHz at 5.0V. It features In-System Programmability via a two-wire bus, programmable reset polarity, and cascading capability through the CEO pin. The component is housed in a 20-lead PLCC package.

Configuration PROMs For FPGAs Procurement Notes

Verify that the ordering suffix 'J' corresponds to the 20-lead PLCC package as specified in the manufacturer's ordering code table. Confirm the 'U' suffix indicates compliance with lead-free and halogen-free requirements. Ensure the selected variant matches the required voltage range and temperature specifications for the target application environment.

Configuration PROMs For FPGAs Selection Notes

Select this component when a 512-kbit capacity is required for FPGA configuration. Consider the 20-lead PLCC package if board space allows for larger footprints compared to SOIC options. Verify compatibility with the specific FPGA master serial mode being utilized. Check for availability of alternative packages like SOIC if smaller form factors are necessary.

Configuration PROMs For FPGAs Part Context

This part belongs to the AT17LV series of FPGA Configuration EEPROMs manufactured by Microchip Technology (formerly Atmel). These configurators provide a cost-effective solution for loading configuration data into SRAM-based FPGAs automatically upon power-up. The series includes various densities ranging from 65 kbit to 4 Mbit.

Configuration PROMs For FPGAs FAQ

What is the function of the CEO pin?

The Chip Enable Output (CEO) pin goes Low when the address counter reaches its maximum value. In a daisy-chain configuration, it connects to the CE input of the next device to enable sequential reading.

How is the device programmed?

Programming is performed using industry-standard programmers or via In-System Programming (ISP) by bringing the SER_EN pin Low to enter the two-wire serial programming mode.
