What is MCP2140-I/SO used for?
The MCP2140-I/SO implements the IrDA physical layer for portable consumer devices, handheld instruments, and legacy equipment requiring short-range infrared serial communication. Operating at up to 5.5 V, it interfaces directly with microcontrollers to add IrDA-compatible wireless data links at distances up to 1 meter without antenna or RF licensing concerns. It is commonly used in point-of-sale terminals, medical data loggers, and embedded systems that exchange data with IrDA-enabled smartphones, printers, or PCs.

Frequently Asked Questions
What supply voltage range does the MCP2140-I/SO support and what IrDA data rates does it handle?
The MCP2140-I/SO operates on a supply voltage up to 5.5 V, making it compatible with both 3.3 V and 5 V microcontroller systems. It supports the IrDA physical layer protocol enabling infrared serial communication at standard rates including 2.4 kbps, 9.6 kbps, 19.2 kbps, 57.6 kbps, and up to 115.2 kbps over short-range IR links of up to 1 meter.
Which applications are best served by the MCP2140-I/SO IrDA controller over a simple UART-to-IR LED approach?
The MCP2140-I/SO is best suited for applications requiring full IrDA protocol compliance rather than simple IR blasting, such as data exchange with IrDA-certified devices like legacy mobile phones, PDAs, printers, and laptops. Its built-in physical layer encoder-decoder at up to 115.2 kbps eliminates the need for timing-critical firmware on the host MCU, reducing software complexity in point-of-sale terminals, medical monitors, and industrial handheld devices.
What is the factory lead time for MCP2140-I/SO and how should procurement teams manage supply risk?
Microchip quotes a factory lead time of 11 weeks for the MCP2140-I/SO in its SOIC-18 package. Procurement teams should place orders at least 12 weeks before production start and consider maintaining a buffer stock covering 4 to 8 weeks of consumption, especially given the YTEOL rating of 3 indicating this part is in a mature lifecycle stage where last-time-buy planning may be necessary for long-production-run programs.
How many pins does the MCP2140-I/SO have and what is its package footprint?
The MCP2140-I/SO uses an 18-pin SOIC-18 package (package equivalence code SOP18,.4) with a 0.4 inch row spacing between the two lead rows. This 18-pad SMD footprint allows the single-function IrDA controller IC to be placed on standard PCB pads using automated pick-and-place equipment, with a peak reflow temperature compatible with lead-free JESD-609 e3 classified components.
