FT25H04S-RT

Overview

The FT25H04S-RT is a 4M-bit (512K-byte) serial flash memory device manufactured by Fremont Micro Devices Ltd. It supports standard SPI with clock frequencies up to 120MHz for fast read operations. The device operates on a single power supply voltage ranging from 2.7V to 3.6V and features an 8-pin SOP8 package. Key electrical characteristics include a maximum active current of 10mA and a standby current of 5uA. It offers a minimum endurance of 100,000 program/erase cycles and includes hardware write protection mechanisms.

Feature Summary

• Supports high-speed SPI communication with fast read capabilities up to 120MHz
• Features flexible architecture with uniform block and sector erase options
• Includes comprehensive data protection via software programmable block protect bits
• Provides low power consumption with minimal active and standby currents

Applications

• Embedded systems requiring non-volatile code storage
• Data logging applications needing reliable write endurance
• Consumer electronics utilizing compact surface-mount packaging
• Industrial control systems requiring hardware write protection

Procurement Notes

Verify the specific suffix 'S-RT' against official datasheets to confirm package type and tape/reel specifications. Confirm availability status as preliminary or final release. Ensure compatibility with existing SPI controller interfaces regarding voltage levels and timing requirements before integration.

Selection Notes

Select this component when a 4M-bit capacity is required with high-speed read performance. Consider the 2.7V to 3.6V operating range for system power design. Evaluate the 100,000 cycle endurance against application write frequency. Verify that the 8-pin SOP8 footprint fits the PCB layout constraints.

Part Context

This part belongs to the FT25H series of serial flash memories from Fremont Micro Devices. The series typically includes variants like the FT25H02 (2M-bit). These devices are designed for general-purpose storage applications where standard SPI interface compatibility and moderate speed are prioritized over ultra-high density or automotive qualification.
