MCP23017-E/SS
by MICROCHIP(美国微芯)
Microchip’s MCP23017-E/SS is an I²C GPIO expander used when a controller needs additional digital input and output lines. It is commonly placed between the host bus and switches, indicators, or other board-level signals, reducing the controller pins devoted to local I/O. The provided library includes a 28-pin KiCad symbol, the 28-pad SSOP-28_L10.2-W5.3-P0.65-LS7.8-BL footprint, and a fitted 3D model for layout inspection. The conversion has been used by 2 ProtoFlow engineers in real designs, establishing verification through practical use of the imported files. Open it directly in ProtoFlow to place the part and continue designing.
