Feature

MCP23017 is a high- IIC interface. It supports the IIC frequency of 100KHz, 400KHz and 1.7MHz. The chip has 3 address pins, which can set up to 8 different addresses. So 8 modules can be connected through two IIC buses to achieve up to 128 IO extensions.
Each IO can be discretionarily configured as input or output, and can set pull up resistort.
16 way I/O extension module of the 12C interface, adopts MCP23017 chip of MicroChip.
This module is flexible in configuration and strong in driving ability. There are many parallel connections.
The IO configured as input can start interrupt function. The IO interface has a strong driving capacity, and the sink current and pull current can reach 25mA.
