PCA9502

8-bit I/O expander with I²C-bus/SPI interface

Rev. 4 — 23 February 2016

Product data sheet

1. General description

The PCA9502 is an 8-bit I/O expander with I²C-bus/SPI host interface. The device comes

in a very small HVQFN24 package, which makes it ideally suitable for hand-held, battery

operated applications.

The device also supports software reset, which allows the host to reset the device at any

time, independent of the hardware reset signal.

2. Features and benefits

2.1 General features

 Selectable I²C-bus or SPI interface

 3.3 V or 2.5 V operation

 Industrial temperature range: 40 C to +85 C

 Eight programmable I/O pins

 Software reset

 Industrial and commercial temperature ranges

 Available in HVQFN24 package

 16 hardware-selectable slave addresses

2.2 I²C-bus features

 Noise filter on SCL/SDA inputs

 400 kbit/s (maximum)

 Compliant with I²C-bus Fast-mode

 Slave mode only

2.3 SPI features

 15 Mbit/s maximum speed

 Slave mode only

 SPI Mode 0

3. Applications

 Factory automation and process control

 Portable and battery operated devices

 Cellular data devices
