GENERAL DESCRIPTION
The HM25Q128A-PWof non-volatile flash memory device supports the standard Serial Peripheral Interface (SPI). Traditional SPI single bit serial input and output (Single I/O or SIO) is supported as well as optional two bit (Dual I/O or DIO) and four bit (quad I/O or QIO) serial protocols. This multiple width interface is called SPI Multi-I/O or MIO.
