AT17LV512-10CU

Configuration PROMs For FPGAs Overview

The AT17LV512-10CU is a 512-kbit serial EEPROM designed for FPGA configuration. It supports 3.0V to 5.5V operation and operates within an industrial temperature range of -40°C to +85°C. The device features In-System Programmability (ISP) via a 2-wire bus and provides a simple serial interface for SRAM FPGAs. It includes programmable reset polarity, write protection mechanisms, and cascading capabilities through the CEO pin.

Configuration PROMs For FPGAs Feature Summary

• Designed specifically to store configuration programs for Field Programmable Gate Arrays (FPGAs).
• Supports In-System Programming (ISP) using a standard 2-wire serial bus interface.
• Features a cascadable read-back capability to support higher-density arrays or additional configurations.
• Includes programmable reset polarity and hardware/software data protection mechanisms.

Configuration PROMs For FPGAs Applications

• Configuration memory for Atmel AT6000, AT40K, and AT94K devices.
• Configuration memory for Altera FLEX and APEX devices.
• Configuration memory for Xilinx XC3000, XC4000, XC5200, Spartan, and Virtex FPGAs.

Configuration PROMs For FPGAs Procurement Notes

Verify that the ordering suffix 'CU' corresponds to the 8-lead Leadless Array Package (LAP) with CuNiAu lead finish as specified in the official Microchip/Atmel ordering information table. Confirm compatibility with the target FPGA's master serial mode requirements before procurement.

Configuration PROMs For FPGAs Selection Notes

Select this component when a 512-kbit non-volatile memory solution is required for FPGA configuration. Ensure the design utilizes the 8-lead LAP package footprint, noting its pin-compatibility with the 8-lead SOIC package but distinct physical dimensions. Verify voltage supply stability within the 3.0V to 5.5V range.

Configuration PROMs For FPGAs Part Context

This part belongs to the AT17LV series of FPGA Configuration EEPROMs manufactured by Microchip Technology (formerly Atmel). The series offers various densities from 65-kbit to 4-Mbit, packaged in options including LAP, PDIP, SOIC, PLCC, and TQFP to accommodate different board space and pin-count constraints.

Configuration PROMs For FPGAs Replacement Considerations

AT17LV512-10JU: Same density and electrical specifications, but housed in a 20-lead PLCC package with Sn lead finish. Requires PCB layout modification due to different package type and pinout.

Configuration PROMs For FPGAs FAQ

Is the AT17LV512-10CU compatible with Xilinx Spartan FPGAs?

Yes, the datasheet explicitly lists compatibility with Xilinx Spartan devices for configuration purposes.

What is the function of the CEO pin on the AT17LV512?

The Chip Enable Output (CEO) pin goes Low when the address counter reaches its maximum value, allowing it to drive the CE input of the next configurator in a daisy-chain setup.
