PCAL6534 Overview
The PCAL6534 is a 34-bit general purpose I/O expander that provides remote I/O expansion for most microcontroller families via the Fast-mode Plus (Fm+) I2C-bus interface. The ultra low-voltage interface allows for direct connection to a microcontroller operating down to 0.8 V. NXP I/O expanders provide a simple solution when additional I/Os are needed while keeping interconnections to a minimum, for example, in...
