MCP23S17-E/SS Microchip Components

Description

The MCP23S17-E/SS device is a product of Microchip Corporation. This product is a 16-bit SPI I/O expander with a serial interface. This product has always been very popular in the market! Welcome new and old customers to buy this product from XT-ShenZhen! It will be our great honor!

The MCP23S17-E/SS devices provide 16-bit general purpose parallel I/O expansion for SPI applications. The serial interface of this product differs from the MCP23017 device.
There are multiple 8-bit configuration registers for input, output and polarity selection in MCP23S17-E/SS devices. By writing to the I/O configuration bits (IODIRA/B), the system host can enable I/O as input or output. Input or output registers hold input or output data. The registers can be read by the system host.
