FT25L04S-RT

Overview

The FT25L04S-RT is a serial flash memory device from Fremont Micro Devices Ltd, offering 4M-bit (512K-byte) storage capacity. It utilizes a standard SPI interface with support for clock frequencies up to 40MHz during fast read operations. The device operates on a single power supply voltage ranging from 1.65V to 1.95V. Key performance metrics include a typical page program time of 2.0ms and sector erase time of 180ms. It features a uniform block/sector architecture with 256-byte programmable pages and supports minimum 100,000 program/erase cycles.

Feature Summary

• Supports standard SPI interface with high-speed clock frequency up to 40MHz for fast read commands.
• Features flexible architecture with uniform blocks and sectors for efficient data management.
• Includes hardware and software data protection mechanisms such as write enable latches and block protect bits.
• Designed for low power consumption with minimal active and standby current requirements.

Applications

• Embedded systems requiring non-volatile code storage
• Data logging applications needing reliable sector-level erasure
• Consumer electronics utilizing small form factor packages

Procurement Notes

Verify the specific suffix 'S-RT' against official ordering information to confirm package type and tape/reel specifications. Ensure voltage compatibility with the 1.65V to 1.95V range before integration. Check datasheet revision history for any updates to electrical characteristics or command sets prior to final design approval.

Selection Notes

Select this component when a 4M-bit capacity is required within a narrow 1.65V-1.95V voltage window. Consider the 40MHz SPI speed for high-throughput read applications. Evaluate the 8-pin package options available in the ordering section to match PCB layout constraints. Confirm endurance requirements align with the 100,000 cycle specification.

Part Context

This part belongs to the FT25L04/02 series of serial flash memories produced by Fremont Micro Devices Ltd. The series includes variants with different capacities and packaging options. The FT25L04 specifically denotes the 4M-bit density version, distinguishing it from the 2M-bit FT25L02 model within the same family.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Verify pinout and command set compatibility if considering alternative manufacturers' 4M-bit SPI flash devices operating at similar voltage levels.
