Frequently Asked Questions

How many configurable I/O pins does the MCP25020-I/P add to a microcontroller via SPI?

The MCP25020-I/P provides 8 configurable I/O pins controlled over SPI. Each of the 8 bits can be independently set as an input or output, allowing flexible GPIO expansion without consuming additional microcontroller pins beyond the 4-wire SPI interface.

Which SPI voltage levels are compatible with the MCP25020-I/P for use with 3.3V microcontrollers?

The MCP25020-I/P supports SPI logic levels compatible with both 3.3V and 5V supply rails, operating over a supply voltage range of 1.8V to 5.5V. This makes it directly interfaceable with modern 3.3V ARM Cortex-M microcontrollers without level-shifting circuitry.

Is the MCP25020-I/P suitable for industrial temperature environments?

Yes, the MCP25020-I/P industrial-grade variant is rated for an operating temperature range of -40°C to +85°C, making it appropriate for factory automation, motor control panels, and outdoor sensor systems that see wide ambient temperature swings.

What footprint does the PDIP-14 package of the MCP25020-I/P use, and is it breadboard-friendly?

The PDIP-14 package has 14 pins on a 2.54 mm (0.1 inch) pitch with a 0.300-inch body width. This standard DIP footprint fits directly into standard breadboards and dual-row IC sockets, making it ideal for prototyping and through-hole PCB assembly.
