There are times when you don’t need much processing power for your project but you do need a lot of I/O pins. It often doesn’t make economic sense to choose a larger microcontroller just to get extra ...
The PCAL6408A is an 8-bit general purpose I/O expander that provides remote I/O expansion for most microcontroller families via the I²C-bus interface. The PCAL6408A is an 8-bit general purpose I/O ...
This 16-bit I/O expander for the two-line bidirectional bus (I2C) is designed to provide general-purpose remote I/O expansion for most microcontroller families via the I2C interface [serial clock (SCL ...
