Frequently Asked Questions
What maximum data rate does the MCP2155-I/P support for IrDA serial communication?
The MCP2155-I/P supports SIR IrDA serial communication at data rates up to 115.2 kbps, which is the standard serial infrared speed. This matches the baud rate of most UART peripherals on popular 8-bit and 32-bit microcontrollers, simplifying firmware integration.
In which package does the MCP2155-I/P come and how does that affect prototyping?
The device is housed in an 18-pin 0.3-inch PDIP through-hole package, making it straightforward to insert into breadboards or prototype boards during development. The 18-pin DIP footprint is widely supported by standard IC sockets, reducing rework effort in early hardware iterations.
When would a designer choose MCP2155-I/P over a discrete IR LED and photodiode approach?
Choosing MCP2155-I/P saves significant design time because it integrates IrDA encoding, decoding, and timing in a single IC, eliminating the need for external pulse-shaping circuits. A discrete approach with a 940 nm IR LED and photodiode typically requires at least 3–5 additional components plus careful timing logic, whereas MCP2155-I/P reduces that to one 18-pin part.
What typical applications benefit most from the MCP2155-I/P infrared encoder/decoder?
Applications such as point-of-sale terminals, industrial handheld scanners, and medical monitoring equipment benefit most, as they require reliable short-range wireless links at 115.2 kbps without RF interference concerns. The device also suits consumer electronics like universal remote controls and PC IR ports where IrDA compliance at distances up to 1 meter is required.
