AP1117D33LA(701): DC power convert, convert to 3.3v. SST25LF020A-33-4C-SAE(U402): SST’s serial flash family features a four-wire, SPI-com-patible interface that allows for a low pin-count package occupying less board space and ultimately lowering total system costs. The SST25LF020A/040A devices significantly improve performance, while lowering power consumption. The total energy consumed is a function of the applied voltage, current, and time of application.
Symbol SCK Pin Name Serial Clock Serial Data Functions To provide the timing of the serial interface. Commands, addresses, or input data are latched on the rising edge of the clock input, while output data is shifted out on the falling edge of the clock input. Input To transfer commands, addresses, or data serially into the device. Inputs are latched on the rising edge of the serial clock. SO Serial Data Output To transfer data serially out of the device.
