AT17LV512A-10PC

Configuration PROMs For FPGAs Overview

The AT17LV512A-10PC is a serial EEPROM configuration memory device manufactured by Atmel. It features a storage density of 512K bits (64K x 8) and operates on a single 5V power supply. The component supports In-System Programming (ISP) via a two-wire interface, allowing for flexible data updates without removal from the circuit board. Designed primarily for storing configuration programs for Field Programmable Gate Arrays (FPGAs), it offers high endurance with over 100,000 write/erase cycles. The device ensures data retention for more than 100 years and includes hardware and software protection mechanisms to safeguard stored information against accidental modification.

Configuration PROMs For FPGAs Feature Summary

• Supports In-System Programming (ISP) via a simple two-wire bus interface for easy integration into existing designs.
• Provides hardware and software data protection mechanisms to prevent unauthorized or accidental data alteration.
• Capable of cascading multiple devices to expand total memory capacity for larger FPGA configurations.
• Features read-back capability to verify configuration data integrity after programming.

Configuration PROMs For FPGAs Applications

• Storing configuration bitstreams for Altera FLEX and APEX series FPGAs
• Programming Lucent ORCA and Xilinx XC3000/XC4000 series programmable logic devices
• Configuration memory for Atmel AT6000, AT40K, and AT94K device families

Configuration PROMs For FPGAs Procurement Notes

Verify the specific suffix 'PC' against official Microchip documentation to confirm package type and temperature range, as suffixes often denote variations in housing or operating conditions. Ensure the source provides an active datasheet rather than a generic family overview. Confirm RoHS compliance status if required for your manufacturing process, as older Atmel parts may have different environmental certifications compared to current Microchip offerings.

Configuration PROMs For FPGAs Selection Notes

Select this component when a non-volatile, serially accessible memory is required for FPGA configuration in systems where pin count is limited. The two-wire interface reduces PCB routing complexity compared to parallel memories. Consider the 10ns access speed and 5V operation voltage compatibility with standard logic levels. Evaluate the need for ISP capabilities versus one-time programmable options based on field update requirements.

Configuration PROMs For FPGAs Part Context

This part belongs to the AT17LV series of serial EEPROMs designed specifically for FPGA configuration applications. Atmel, now part of Microchip Technology, developed this line to replace parallel PROMs with more flexible serial alternatives. The series supports various densities and voltages, with the LV variant indicating low-voltage or standard 5V operation depending on the specific sub-series documentation. These devices are integral to the boot and configuration processes of many legacy programmable logic devices.

Configuration PROMs For FPGAs Replacement Considerations

Direct replacements include other AT17LV512 variants with compatible pinouts and electrical characteristics. Verify that substitute parts support the same two-wire ISP protocol and voltage range. Cross-reference with Microchip's current portfolio for equivalent density and interface specifications.
