NXP I2C Application Note stating the maximum byte transfer

[lpestanas]

Hi NXP Team,

Is there an existing I2C Device who can handle more than 255bytes in one Single Transaction?

Please share an application note or literature if this is not possible.

Thanks and Good Day,

Hi @lpestanas 

The standard I2C devices are generally limited by the 255-byte payload size per transaction due to the I2C protocol's use of an 8-bit register for data length.

To handle more than 255 bytes in one transaction, you can Use Multiple Transactions.

Hi Harry,

Thanks, it means that I need to use multiple transactions to divide an input write of 4kB for example.
