Abstract

The disclosure provides a daisy-chain serial peripheral interface (SPI) integrated circuit (IC) and an operation method thereof. The daisy-chain SPI IC includes a first MISO interface circuit, a second MISO interface circuit, a first data enable (DE) interface circuit, and a second DE interface circuit. When the daisy-chain SPI IC is a target slave circuit selected by a master IC for reading target data, the first DE interface circuit outputs a DE signal to the master IC, and the first MISO interface circuit sends back the target data to the master IC based on the timing of the DE signal. When the daisy-chain SPI IC is not the target slave circuit, the signal received by the second DE interface circuit is transmitted to the first DE interface circuit, and the data received by the second MISO interface circuit is transmitted to the first MISO interface circuit.
