Memory IC datasheet and documents for SST26WF040BA-104I/MF
Memory IC Overview
The SST26WF040BA-104I/MF is a NOR flash memory device from Microchip Technology's SST26 series. It features a storage capacity of 4 Mbit organized as 512K x 8 bits. The component operates with a supply voltage range of 1.8V and supports Serial Quad I/O (SQI) interface with a maximum clock frequency of 104 MHz. It is housed in an 8-pin TDFN package and is rated for industrial temperature ranges.
Memory IC Feature Summary
- Utilizes high-performance SuperFlash technology for reliable data retention.
- Supports low-voltage operation at 1.8V for power efficiency.
- Enables high-speed data transfer via Serial Quad I/O interface.
Memory IC Applications
- Embedded systems requiring non-volatile code storage
- Industrial control applications
- Consumer electronics with limited power budgets
Memory IC Procurement Notes
Verify the specific suffix 'MF' corresponds to the required TDFN-8 package variant. Confirm that the 1.8V operating voltage aligns with the target system's power rails, as this differs from the 2.3V-3.6V variants in the broader SST26 family. Ensure humidity sensitivity handling protocols are followed during assembly.
Memory IC Selection Notes
Select this part when a 4 Mbit capacity and 1.8V supply are mandatory. Compare against SST26VF040AT for 2.3V-3.6V compatibility if the system voltage differs. Consider the TDFN-8 footprint constraints versus SOIC or WDFN options available in other SST26 models.
Memory IC Part Context
This component belongs to the SST26WF040B series, which expands Microchip's 1.8V SQI Super Flash portfolio. It complements higher-capacity devices like the 8Mb and 16Mb variants, offering a compact solution for smaller firmware requirements while maintaining industry-leading erase times and reliability standards.
Memory IC Replacement Considerations
SST26WF040BAT-104I/NP offers similar 4Mb capacity and 1.8V operation but uses a UDFN-8 package. SST26VF040AT-104I/MF provides the same capacity and pinout but requires a 2.3V to 3.6V supply voltage.
