AS25F364MQ 64Mb (x1 / x2 / x4) 3.3 V SERIAL MULTI I/O NOR FLASH MEMORY
▲AS25F364MQ is 67,108,864 bits serial Flash memory, which is configured as 8,388,608 x 8 internally. When it is in two or four I/O mode, the structure becomes 33,554,432 bits x 2 or 16,777,216 bits x 4. AS25F364MQ feature a serial peripheral interface and software protocol allowing operation on a simple 3-wire bus while it is in single I/O mode. The three bus signals are a Serial Clock (C), a serial data input (DI), and a serial data output (DO). Serial access to the device is enabled by S\ input.
▲When it is in two I/O read mode, the DI pin and DO pin become IO0 pin and IO1 pin for address/dummy bits input and data output. When it is in four I/O read mode, the DI pin, DO pin and W\ pin become IO0 pin, IO1 pin, IO2 pin and IO3 pin for address/dummy bits input and data output. After program/erase command is issued, auto program/ erase algorithms which program/ erase and verify the specified page or sector/block locations will be executed. Program command is executed on byte basis, or page (256 bytes) basis, or word basis for erase command is executed on sector (4K-byte), block (32K-byte), or block (64K-byte), or whole chip basis.
▲To provide user with ease of interface, a status register is included to indicate the status of the chip. The status read command can be issued to detect completion status of a program or erase operation via WIP bit. Advanced security features enhance the protection and security functions, please see security features section for more details.
▲When the device is not in operation and S\ is high, it is put in standby mode and draws less than 10μA DC current.
