Key Features
- 4 Mbit NOR flash with 40 MHz SPI clock for fast embedded firmware and data storage
- 100,000 write/erase cycle endurance with 20-year minimum data retention for long-life applications
- Ultra-compact 8-pin USON (UDFN-8) package ideal for space-constrained IoT and wearable designs
Applications
SST25WF040BT-40I/NP is used in IoT edge nodes, wearable devices, and consumer electronics requiring compact non-volatile code or data storage at 40 MHz SPI speeds. It is well suited for embedded systems that store firmware, boot code, or configuration data with infrequent update cycles. The USON-8 package enables ultra-thin PCB designs where standard SOIC footprints are too large.

Frequently Asked Questions
What is the maximum clock frequency and memory density of SST25WF040BT-40I/NP?
SST25WF040BT-40I/NP operates at a maximum SPI clock frequency of 40 MHz and provides a memory density of 4 Mbit (4,194,304 bits). This combination makes it suitable for firmware storage and fast boot applications in microcontroller-based embedded systems that require quick access to stored code.
How long can SST25WF040BT-40I/NP retain data, and how many erase cycles does it support?
SST25WF040BT-40I/NP guarantees a minimum data retention time of 20 years under normal operating conditions. It also supports up to 100,000 write/erase cycles per sector, making it a reliable choice for applications that require periodic firmware updates or configuration changes over the lifetime of the product.
What package does SST25WF040BT-40I/NP use, and how does it fit into compact IoT PCB layouts?
SST25WF040BT-40I/NP is housed in an 8-pin USON (UDFN-8) package, which has a very small footprint compared to standard SOIC-8 packages. This compact outline is especially valuable in wearables, sensor nodes, and IoT modules where board area is at a premium and PCB thickness must remain under 1 mm.
What is the factory lead time for SST25WF040BT-40I/NP and how should supply chain teams plan orders?
The factory lead time for SST25WF040BT-40I/NP is 6 weeks. Supply chain planners should schedule purchase orders at least 6 to 8 weeks before production start dates. For high-volume consumer electronics runs, maintaining a safety stock buffer of 8 weeks is recommended to prevent line stoppages caused by memory component shortages.
