FT25H16S-RT

Overview

The FT25H16 is a 16M-bit (2048K-byte) serial flash memory device manufactured by Fremont Micro Devices. It supports Standard, Dual, and Quad SPI interfaces with high-speed clock frequencies up to 120MHz for fast read operations under a 30pF load. The device features a flexible architecture comprising 4K-byte sectors and 32/64K-byte blocks, with page programming capabilities of 256 bytes per page. It operates on a single power supply voltage ranging from 2.7V to 3.6V.

Feature Summary

• Supports Standard, Dual, and Quad SPI communication protocols with bidirectional I/O pins for enhanced data transfer rates.
• Includes software and hardware write protection mechanisms via Block Protect bits and the WP# pin.
• Features advanced security registers with one-time programmable lock capabilities.
• Offers program/erase suspend and resume functionality to allow interruption and resumption of memory operations.

Applications

• Embedded systems requiring non-volatile code storage
• Data logging applications needing sector-level erasure
• Industrial control systems utilizing hardware write protection
• Consumer electronics storing firmware or configuration data

Procurement Notes

Verify the specific package variant required, as the FT25H16 is available in multiple 8-pin formats including SOP8, DIP8, VSOP8, and TSSOP8. Confirm that the design accommodates the specified voltage range of 2.7V to 3.6V. Ensure compatibility with the chosen SPI mode, particularly if utilizing Quad I/O commands which require setting the Quad Enable bit in the status register.

Selection Notes

Select this component when a 16M-bit capacity is required with support for high-speed Quad SPI access. It is suitable for designs needing granular block protection and security register locking. Consider the available package options such as SOP8 or TSSOP8 based on board space constraints. Ensure the host controller supports the necessary command set for dual and quad operations if maximum throughput is desired.

Part Context

The FT25H16 belongs to the FT25H series of serial flash memories from Fremont Micro Devices. This series is designed for applications requiring reliable non-volatile storage with flexible protection schemes. The device integrates a high-voltage generator on-chip, eliminating the need for external programming voltages.
