AT17LV512A-10JC

Configuration PROMs For FPGAs Overview

The AT17LV512A-10JC is a 524,286 x 1-bit serial configuration memory device manufactured by Atmel (Microchip). It utilizes a low-power CMOS EEPROM process and operates on a single 3.3V ± 10% supply voltage. The component is housed in a 20-lead PLCC package with a maximum clock frequency of 10 MHz. Designed for FPGA configuration, it supports in-system programming via a two-wire bus interface.

Configuration PROMs For FPGAs Feature Summary

• Supports in-system programming through a simple two-wire bus interface
• Features a system-friendly READY pin to indicate valid power levels during startup
• Allows programmable reset polarity configuration via internal EEPROM bytes
• Enables cascading and read-back capabilities for multi-device or high-density array configurations

Configuration PROMs For FPGAs Applications

• Configuration storage for Altera FLEX and APEX field programmable gate arrays
• Configuration storage for Xilinx XC3000, XC4000, XC5200, Spartan, and Virtex devices
• Configuration storage for Lucent ORCA and Atmel AT6000/AT40K FPGAs
• System initialization memory for embedded logic circuits requiring reliable power-up sequencing

Configuration PROMs For FPGAs Procurement Notes

Verify the specific suffix 'A' against official Microchip documentation to confirm revision differences from standard AT17LV512 models. Ensure the 3.3V LV version matches the target FPGA voltage requirements. Confirm package integrity for the 20-lead PLCC form factor. Check for RoHS compliance status as legacy Atmel parts may vary. Validate that the 10 MHz speed grade meets the system timing constraints.

Configuration PROMs For FPGAs Selection Notes

Select this component when a 512K-bit capacity is required for SRAM-based FPGA configuration. Choose the LV variant specifically for 3.3V systems to ensure voltage compatibility. Consider the PLCC package if the design board layout accommodates leaded packages. Verify that the two-wire interface aligns with the microcontroller or FPGA configuration pins available on the target platform.

Configuration PROMs For FPGAs Part Context

This part belongs to the AT17 Series of FPGA Configurators, designed to replace traditional PROMs. The series offers reprogrammability and lower cost compared to one-time programmable alternatives. Atmel was acquired by Microchip Technology, which continues to support these configuration memory lines for legacy and new designs involving SRAM FPGAs.

Configuration PROMs For FPGAs Replacement Considerations

The AT17C512-10JC serves as a 5V equivalent within the same family. Cross-referencing with the AT17LV512-10JC is necessary to distinguish between voltage variants. Ensure any substitute maintains the 20-lead PLCC footprint and 10 MHz operational speed.
