I2C, SPI, I3C Interface Devices
The I2C-bus appears in virtually every application—from cellular handsets and LED blinkers to LCD displays. Our leadership position in I2C-bus devices offers you a vast portfolio to address all your design needs. In addition many of these product groups now include a higher speed I3C-bus or SPI interface.
I2C, SPI, I3C Interface Device Families
Bus Controllers and Bridge ICs
Bridge ICs allow designers to connect devices that use different serial buses.
DACs and ADCs
Used for communication and protocol conversion.
DIP Switch
Replacement for mechanical switches.
General Purpose I/O (GPIO)
Drives LED and monitor switches without using any microprocessor pins.
LED Controllers
For blinking, dimming and color mixing LEDs; frees the microprocessor for other purposes.
Multiplexers/Switches
Connects an upstream I2C-bus to any combination of downstream I2C buses.
Real-Time Clocks (RTC)
Targets applications needing accurate timekeeping: ultra-low-power, high-temperature tolerant, temperature compensated and high-accuracy.
Repeaters, Hubs and Extenders
Buffers I2C signals for a more reliable system and better noise immunity.
Temperature Sensors
Offers high-resolution solutions for thermal management—from process control to computing applications.
Voltage Level Translators
Allows easy connection between a wide range of supply voltage domains.
Serial Peripheral Interface (SPI) Devices
Full duplex synchronous serial interface consisting of four signals used for short distance high-speed communications.
I3C Interface Devices
Provides a scalable, medium-speed, utility and control bus for connecting peripherals to an application processor
