Short-Form Datasheet IXP3114, IXP3104 (Renesas)

Short-Form Datasheet IXP3114/IXP3104 I3C Basic 1:4 GPIO Expander
Description Features
The IXP3114/3104 is an I3C Basic 1:4 General I/O • 1:4 General Purpose Input/Output Expander Expander with integrated Temperature Sensor used (GPIO) for various motherboard applications. The • Two-wire programmable I²C or I3C bus serial IXP3114/3104 has four configurable I/O pins that interface can be configured as either input only, output only • Single device load on the Host bus or input/output on a local interface. The GPIO pin is a CMOS push-pull buffer or open-drain with a • Up to 12.5MHz transfer rate configurable pull-up resistor. The voltage levels for • Single 1.8V power supply input either open drain or push pull are independently • 1.0V VLDO output at VIO pin configurable. • Supports 1.0V, 1.1V, and 1.2V push-pull IO levels The IXP family I/O expander is typically used when • Supports 1.0V, 1.1V, 1.2V, 1.8V, 2.5V, and 3.3V there is a need for additional GPIO input and output open-drain I/O levels in an application. • Integrated Temperature Sensor; 0.5°C accuracy with 0.25°C resolution • Bus reset function • Packet Error Check (PEC) function • Parity Error Check function • Up to 8 unique addressing • Programmable I²C, I3C bus addressing scheme • In-Band Interrupt (IBI) • 9-pin thermally enhanced DFN package • Temperature: Industrial range of -40°C to 125°C
