描述
这 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.
• 16-bit remote bidirectional I/O port
– I/O pins default to input
• High-speed I2C™ interface (MCP23017)
– 100 千赫
– 400 千赫
-1.7兆赫
• High-speed SPI interface (MCP23S17)
– 10 兆赫 (max.)
• Three hardware address pins to allow up to eight devices on the bus
• Configurable interrupt output pins
– Configurable as active-high, active-low or open-drain
• INTA and INTB can be configured to operate independently or together
• Polarity Inversion registerto configure the polarity of the input port data
• External Reset input
• Low standby current: 1 μA (max.)
