I2C Bus Protocol Multibyte Write. For the Multibyte Write mode, the MODE pin must be at VIH. The Multibyte Write mode can be started from any address in the memory. The master sends from one up to 8 bytes of data, which are each acknowledged by the mem- ory. The transfer is terminated by the master gen- erating a STOP condition. The duration of the write cycle is tW = 10ms maximum except when bytes are accessed on 2 rows (that is have different values for the 5 most significant address bits A7- A3), the programming time is then doubled to a maximum of 20ms. Writing more than 8 bytes in the Multibyte Write mode may modify data bytes in an adjacent row (one row is 16 bytes long). However, the Multibyte Write can properly write up to 16 consecutive bytes only if the first address of these 16 bytes is the first address of the row, the 15 following bytes being written in the 15 following bytes of this same row. Page Write. For the Page Write mode the MODE pin must be at VIL. The Page Write mode allows up to 16 bytes to be written in a single write cycle, provided that they are all located in the same ’row’ in the memory: that is the 4 most significant mem- ory address bits (A7-A4) are the same inside one block. The master sends from one up to 16 bytes 8/16 ST24/25C08, ST24/25W08 |
