I 2 C General Purpose I/O (GPIO) Our industry-leading General Purpose I/O (GPIO) expanders provide 4, 8, 16, 24 or 40 general-purpose I/O pins for the CPU via the I 2 C-bus to help designers reduce board space and complexity while simplifying software development and lowering overall system cost.
Analog Devices’ family of mobile I/O expanders are ideal for smartphone designs and portable devices that require a large extended keypad and/or expanded I/Os such as inventory scanners, medical equipment, and meter readers. Microprocessors in portable systems are GPIO constrained due to the number of functions they must interface with and control.
Interface – I/O Expanders Remote 16-Bit I2C and SMBus, Low-Power I/O Expander With Interrupt Output and Config Registers 24-VQFN -40 to 85 Enlarge Mfr. Part No.
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.
