EPC1LC20N

Configuration PROMs For FPGAs Overview

The Altera EPC1LC20N is a serial configuration memory device designed for SRAM-based programmable logic devices. It utilizes Flash technology to store configuration data, ensuring non-volatile retention of the FPGA bitstream. The component operates within a voltage range of 3V to 3.6V and supports a maximum clock frequency of 10 MHz. It features a storage capacity of 1.6 Mbit and is housed in a PLCC-20 package. The device functions as a system-in-programmable PROM, allowing for reconfiguration of connected FPGAs without removing the memory chip from the circuit.

Configuration PROMs For FPGAs Feature Summary

• Provides non-volatile storage for FPGA configuration data using Flash memory technology.
• Supports system-in-programmable operations for reconfiguring connected programmable logic devices.
• Operates with standard 3.3V power supply requirements compatible with typical logic levels.

Configuration PROMs For FPGAs Applications

• Configuration storage for Altera Cyclone series FPGAs
• Configuration storage for Altera APEX series FPGAs
• System-in-programmable memory for industrial control boards

Configuration PROMs For FPGAs Procurement Notes

Verify the specific suffix 'N' indicates lead-free compliance and RoHS status against current manufacturer documentation. Confirm package integrity for the PLCC-20 form factor during inspection. Ensure the source document explicitly lists this part number as active or identifies its end-of-life status, as availability may vary significantly across distributors.

Configuration PROMs For FPGAs Selection Notes

Select this component when a small-capacity, cost-effective solution is required for configuring low-to-medium density SRAM-based FPGAs. The PLCC-20 package is suitable for through-hole or specific surface-mount designs requiring this footprint. Verify that the 1.6 Mbit capacity meets the size of the target FPGA configuration file before finalizing the design.

Configuration PROMs For FPGAs Part Context

This device belongs to the EPC1 family of configuration PROMs manufactured by Altera. These components are specifically engineered to interface with Altera's SRAM-based FPGA families, such as Cyclone and APEX. They serve as the primary non-volatile storage medium, replacing older parallel configuration methods with a simpler serial interface architecture.

Configuration PROMs For FPGAs Replacement Considerations

Direct replacements include other members of the EPC1 family with equivalent or larger capacities, such as the EPC1441LC20N. When substituting, ensure the new device supports the same PLCC-20 package and maintains compatibility with the target FPGA's configuration protocol.
