MCP23S18-E/MJ MCP23S18 by Microchip Technology
16-Bit, Open Drain I/O Expander with I2C Interface
| Status: | Unknown |
|---|---|
| Series: | - |
| RoHS: | Unknown |
• MCP23018 - I2C interface
• MCP23S18 - SPI interface
The MCP23X18 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.
