Product Description
Microchip MCP23S17T-E/ML is a versatile 16-channel I/O expander designed for SPI bus interface applications. Packaged in a compact 28-pin QFN surface mount device, it measures 6mm in length and 1mm in height, making it suitable for dense PCB layouts. The device operates from a supply voltage range of 1.8V to 5.5V, accommodating different system power configurations.
This I/O expander supports clock frequencies up to 10 MHz, allowing high-speed communication on SPI lines. It features multiple 8-bit configuration registers enabling system masters to set each of the 16 channels as inputs or outputs, and to invert input polarity as necessary. The registers are fully readable, which facilitates system diagnostics and status monitoring.
The MCP23S17T-E/ML device can be cascaded in groups up to eight on a single SPI bus, expanding the number of I/O channels without complex wiring. Each I/O port supports up to 25mA sink/source current, capable of controlling LEDs, relays, or other peripherals directly.
Operating over a robust industrial temperature range of -40°C to 125°C, the device ensures reliable performance in harsh environments such as automotive, industrial automation, and instrumentation. Its small footprint and surface mount package make it ideal for compact embedded designs.
The MCP23S17T-E/ML is widely applicable in electronic component and semiconductor sectors, useful in industrial control, laboratory setups, and embedded system projects requiring scalable digital I/O expansion.
The device offers 16 configurable digital I/O channels. Implements SPI interface communication up to 10 MHz clock speed. Supports cascading of up to 8 devices on one SPI bus. Compact QFN 28-pin surface mount package with 6mm × 1mm dimensions.
Wide operating voltage range from 1.8V to 5.5V. Industrial temperature range operation from -40°C to 125°C. 25mA drive capability per I/O channel. Polarity inversion and readable input/output registers. Enables I/O expansion in industrial and electronic applications.
