PCAL9722HN, ultra low-voltage translating 22-bit SPI I/O expander with Agile I/O features,
interrupt output and reset
The PCAL9722HN-ARD evaluation board is easy to test and designed for the PCAL9722HN
which is a 22-bit general purpose I/O expander that provides remote I/O expansion for most
microcontroller families via the SPI interface. The PCAL9722HN-ARD uses the LPC55S69-EVK
MCU board to provide an easy to use evaluation platform.
