Product Description
Microchip MCP23S17-E/SO is a 16-channel I/O expander engineered for electronics designers seeking robust expansion of digital input and output capabilities. The component is housed in a compact SOIC 28 surface mount package that readily suits automated PCB assembly and space-constrained applications.
This device leverages a Serial Peripheral Interface (SPI), offering users an efficient and reliable means of communicating with microcontrollers or processors that require additional I/O capacity. Operating at a maximum clock frequency of 5MHz, the MCP23S17-E/SO supports fast data transfer suitable for responsive control and monitoring environments.
The expander features a broad supply voltage range of 1.8V to 5.5V, ensuring compatibility with contemporary low- and high-voltage digital systems. It is designed to maintain performance stability across a wide temperature spectrum, from -40°C to 125°C, making it appropriate for demanding industrial and commercial installations.
It incorporates 28 pins within its surface-mount SOIC package, facilitating easy soldering and reliable connections to PCB boards. Its physical form factor (17.9mm × 2.65mm) makes it ideal for integration where space is at a premium, enabling dense component placement without compromising functionality.
The MCP23S17-E/SO device does not carry automotive or explicit RoHS certifications in the provided evidence, but stands out for its versatility as a parallel interface peripheral for digital circuit expansion. Key use cases include automation control systems, instrumentation, embedded hardware, industrial panel interfaces, and any application requiring modular digital channel expansion with minimal hardware footprint.
Microchip’s MCP23S17 series has been widely adopted for its dependable electronic performance, ease of integration, and flexibility in circuit design. Engineers and system integrators will appreciate the reliability, parametric flexibility, and expanded configuration options this component provides.
