IXP3114/IXP3104
I3C Basic 1:4 GPIO Expander Description Features The IXP3114/3104 is an I3C Basic 1:4 General I/O
Expander with integrated Temperature Sensor used
for various motherboard applications. The
IXP3114/3104 has four configurable I/O pins that
can be configured as either input only, output only
or input/output on a local interface. The GPIO pin is
a CMOS push-pull buffer or open-drain with a
configurable pull-up resistor. The voltage levels for
either open drain or push pull are independently
configurable. • 1:4 General Purpose Input/Output Expander
(GPIO) • Two-wire programmable I²C or I3C bus serial
interface • Single device load on the Host bus • Up to 12.5MHz transfer rate • Single 1.8V power supply input • 1.0V VLDO output at VIO pin • 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 I/O levels • 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 The IXP family I/O expander is typically used when
there is a need for additional GPIO input and output
in an application. Applications
• Mobile devices • Embedded computing • PCs/notebooks • Servers Figure 1. Block Diagram Mar.3.20 Page 1 IXP3114/IXP3104 Ordering Information
