FT25H04T-RB

Overview

The FT25H04T-RB 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. It features a uniform block sector architecture with 4K-byte sectors and 64K-byte blocks, allowing for flexible data organization. The memory includes hardware write protection mechanisms and supports page programming of 256 bytes.

Feature Summary

• Supports high-speed serial peripheral interface communication with fast read capabilities
• Features uniform block sector architecture for flexible memory management
• Includes hardware-based software protection modes to prevent unauthorized writes
• Operates on a single low-voltage power supply for energy efficiency

Applications

• Embedded systems requiring non-volatile code storage
• Data logging applications needing reliable sector erase capabilities
• Consumer electronics utilizing compact surface-mount packages

Procurement Notes

Verify the specific package variant required, as the FT25H04 series supports multiple pin configurations including SOP8, TSSOP8, and DIP8. Confirm that the design accommodates the 2.7V to 3.6V operating range. Ensure compatibility with standard SPI mode 0 and mode 3 signaling protocols before integration into the final product assembly.

Selection Notes

Select this component when a 4M-bit capacity is required with high-speed read performance. Consider the FT25H04T-RB for designs needing robust write protection features via status register bits. Evaluate the available package options against board space constraints, ensuring the chosen footprint matches the specific mechanical requirements of the application.
