MCP23S08-E/SS MCP23S08 by Microchip Technology
8-bit I/O Expander with SPI Interface.
| Status: | Unknown |
|---|---|
| Series: | - |
| RoHS: | Unknown |
• MCP23008 – I2C interface; three address pins
• MCP23S08 – SPI interface; two address pins
The MCP23X08 consists of multiple 8-bit configuration registers for input, output and polarity selection. The system master can enable the I/Os as either inputs or outputs by writing the I/O configuration bits. The data for each input or output is kept in the corresponding Input or Output register. The polarity of the Input Port register can be inverted with the Polarity Inversion register. All registers can be read by the system master.
