Working Principle of AT25DF321A-SH-B

AT25DF321A-SH-B uses a 25-pin small-sized chip as its memory storage unit, and is divided into two blocks: CMOS logic and flash memory. The CMOS logic includes Control Logic that provides the interface functions between the Control Bus and the Memory Array, such as Standby Control and Serial Flash Interface. The Memory Block is an array of 682K words of 8-bit each, while the internal organization is 64 page mode, each page has 512 bytes of memory. The control logic provides a standard industry serial port interface, a control bus, a status register and an optional higher speed split bus. It provides several commands, such as sector erase, block erase, byte programming, chip erase, timeout write protection and status register, etc. It supports Quad SPI interface, which enables fast data transfer, and also supports data protection.
