9 I2C Interface
The I2C interface gives access to the chip registers. It complies with the I2C protocol specifications, restricted to the
slave side of the communication.
The device uses a Generic Fast-Mode (400 KHz) I2C Slave Interface in accordance with the I2C bus standard. Its
characteristics can be summarized as follows:
9.1 General Features
Slave only operation
Fast mode operation (up to 400 kHz)
Combined read and write mode support
General call reset support
7-bits default slave address 0x48. Can be changed by fuse and by pinout (D0 and D1).
The interface handles I2C communication at the transaction level. A read transaction is an external request to get the
content of system memory location and a write transaction is an external request to write the content of a system
memory location.
The default I2C slave address is 0x48, 1001000 in binary. This is the standard part I2C slave address. Other addresses
between 1000000 and 1001111 are available.
9.2 Other Slave Address Options
Slave address might be diffenciated (2 fuse-programmed bits + 2 LSBs given by 2 GPIO inputs):
Address bit 3 and bit 2 (100XXxx ) can be changed in production by fuse. Other values are available by special
request. Please contact Semtech Sales for more information. Otherwise, default value is “00”.
The last significant bits (100xxXX ) can be defined by the GPIO pin D0 and D1. This mode is not set by default at
startup, it must be activated in a register with a command. Default value is “00”.
