Frequently Asked Questions

What maximum data rate does the MCP2122-E/P support over its IrDA link?

The MCP2122-E/P supports IrDA SIR data rates up to 115.2 kbps, which is sufficient for transferring configuration files, short data logs, or firmware parameters between a host and an embedded device within a 1-meter range without any cable connection.

How does the MCP2122-E/P interface with a microcontroller's UART peripheral?

The device connects directly to a standard 3-wire UART (TX, RX, ground) operating at 5V logic levels, requiring no firmware changes or software protocol stack. The MCP2122-E/P handles all IrDA pulse encoding and decoding internally, making integration straightforward for any 8-bit or 32-bit microcontroller with a hardware UART.

Which applications benefit most from using the MCP2122-E/P instead of a Bluetooth or Wi-Fi module?

Applications needing deterministic point-to-point communication within 1 meter, such as medical device programming, retail POS terminals, or industrial calibration tools, benefit from IrDA's line-of-sight security model. The MCP2122-E/P costs significantly less than a Bluetooth module and requires only 5V power with no pairing or radio certification overhead.

Does the 8-pin PDIP package of the MCP2122-E/P support hand-soldering for prototype builds?

Yes, the 8-pin PDIP package with 0.3-inch row spacing is fully hand-solderable on standard perfboard or 2.54 mm pitch PCB pads. This through-hole form factor suits prototyping, classroom labs, and low-volume production where SMD assembly equipment is unavailable, while keeping the total BOM footprint under 50 mm² board area.
