The SST26VF064BA-104I/SM is a 64 Mbit Serial Quad I/O (SQI) flash memory device designed for low-power, high-performance operation in a low pin-count package. It supports both SQI and traditional SPI protocols (x1/x2/x4) at a maximum clock frequency of 104 MHz. This 'BA' variant defaults at power-up with the WP# and HOLD# pins disabled to immediately enable Quad I/O operations. The device features a single 2.3V to 3.6V supply for read and write operations, a low standby current of 15 µA (typical), and fast sector/block erase times. Its high speed, flexible erase capabilities, and superior reliability make it suitable for a wide range of applications requiring fast data transfer and non-volatile storage.
