The SST25WF040BT-40I/CS is a 4 Mbit SPI serial flash memory device from Lingto Electronic Limited, designed for low power consumption and high performance. It operates with a single voltage supply ranging from 1.65V to 1.95V and supports SPI-compatible communication at clock frequencies up to 40 MHz. The device features dual input/output support for fast read operations and has a typical active read current of 4 mA, with standby and power-down mode currents of 7 ¬µA and 2 ¬µA, respectively. This memory device offers a high endurance of 100,000 write/erase cycles and data retention exceeding 20 years. It includes flexible erase capabilities with uniform 4 KByte sectors and 64 KByte overlay blocks, along with a page program mode of 256 bytes per page. Typical erase times are 400 ms for chip erase, 40 ms for sector erase, and 80 ms for block erase, while page programming takes approximately 0.8 ms for 256 bytes. The SST25WF040BT-40I/CS is available in both 8-lead SOIC and 8-contact USON packages, making it suitable for various applications, including those requiring operation in industrial temperature ranges from -40¬8C to +125¬8C. The device is RoHS compliant, ensuring it meets environmental standards.
