Working Principles

IS25LQ032B-JBLE utilizes the SPI interface to communicate with the host device. When data needs to be stored, the host device sends commands and data to the chip through the SPI bus. The chip then performs the necessary operations, such as erasing sectors or programming bytes, to store the data in its memory cells. During read operations, the chip retrieves the requested data and sends it back to the host device.
