MCHPSST25PF040CT-40V/NP
Overview
The SST25PF040CT-40V/NP is a 4Mbit Serial Flash memory device utilizing a 4-wire, SPI-compatible interface and Microchip's proprietary SuperFlash technology. It operates across a 2.3V to 3.6V supply range and supports clock frequencies up to 40 MHz, including Dual I/O read operations. This memory is housed in a compact 2mm x 3mm USON package and is rated for Industrial Plus temperatures up to 105 degrees Celsius.
Why Choose This Part
The use of SuperFlash technology results in significantly faster program and erase times compared to conventional Flash, reducing manufacturing throughput times. Its small 8-contact USON footprint and low standby current of 50uA make it ideal for high-density, power-sensitive designs.
Applications
Key Specifications
Getting Started
Integration requires a standard SPI controller typically found on most MCUs; ensure the host supports 2.3V-3.6V logic levels. Developers can use the Microchip SST25 series software drivers or generic SPI Flash libraries, as the device supports standard JEDEC ID and command sets. Testing can be performed using any SPI-enabled development board or a dedicated serial flash programmer.
