Microchip (MCP23S09-E/SO) I/O Expander, 8bit, 10 MHz

Product Overview
The MCP23S09-E/SO is a 8-bit I/O Expander with SPI interface operating at 10MHz. The MCP23X09 device provides 8-bit, general purpose parallel I/O expansion for I²C bus or SPI applications. The MCP23X09 consists of multiple 8-bit configuration registers for input, output and polarity selection. The system master enables 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.

Low standby current as low as 1µA
High-speed SPI interface at 10MHz
Configurable interrupt output pins - Configurable as active-high, active-low or open-drain
Configurable interrupt source - Interrupt-on-change from configured defaults or pin change
Polarity inversion register to configure the polarity of the input port data
External reset input

Applications
Industrial, Automotive
