App note: I2C interface connects compact flash Card to microcontroller

Sunday, October 26th, 2014

CF cards needs a lot of I/O resources in order to communicate, here's MAXIM's solution(PDF) using their MAX7311 I/O expander to interface these type of data storage devices. This application note explains how to use an I2C I/O extender to connect a compact-flash (CF) card to the I2C interface of...

App note: Low Voltage Agile I/O GPIO Input/Output Characteristics

Saturday, August 23rd, 2014

App note (PDF) on NXP's Agile I/O expander, discussing its capabilities and how to use it efficiently. I2C-bus GPIO devices are widely used and expand a control processor’s pins to 8-, 16- or 24- bits of general-purpose input or output. The characteristic of these I/O needs to be accurately known...
