Short-Form Datasheet IMX3112 I3C Basic 1:2 Bus Multiplexer
Description Features
The IMX3112 is a dual bidirectional 1:2 translating • 1:2 bus multiplexer multiplexer for I3C/I²C bus. The input HSDA/HSCL • Two-wire programmable I²C or I3C bus serial pair can fan out to two output pairs (or channels), interface either individual output channel can be selected. • Single device load on the Host bus Applications with slave devices that share the same • Up to 12.5MHz transfer rate address can use this multiplexer to prevent slave • address conflicts. By selecting the proper output Single 1.8V power supply input channel, the I3C/I²C master can access a large • 1.0V VLDO output at VIO pin number of devices across both ports. • Supports 1.0V, 1.1V, and 1.2V Push-Pull IO levels • Supports 1.0V, 1.1V, 1.2V, 1.8V, 2.5V, and 3.3V open-drain IO levels • Integrated Temperature Sensor; 0.5°C accuracy with 0.25°C resolution • Packet Error Check (PEC) function • Parity Error Check function • Bus reset function • In-band Interrupt (IBI) • Up to 8 unique addressing • Programmable I²C, I3C bus addressing scheme • 9-pin thermally enhanced DFN package • Temperature: Industrial range of -40 °C to 125°C
