Frequently Asked Questions
What is the maximum data rate the MCP2140-I/P supports over an IrDA link?
The MCP2140-I/P supports IrDA SIR (Serial Infrared) mode with a maximum data rate of 115.2 kbps. It also supports lower standard baud rates from 1200 bps upwards, with automatic baud rate detection, so the host UART does not need to be manually configured for each speed.
How does MCP2140-I/P simplify the integration of IrDA into an existing UART-based design?
The MCP2140-I/P integrates all IrDA encoding, decoding, and framing functions internally, so only a standard UART port on the host MCU is needed. This eliminates the need for external encoder/decoder ICs, cutting BOM by several components and reducing PCB area. The 18-pin PDIP package also makes it easy to drop into prototype boards.
What are the voltage compatibility and temperature ratings for MCP2140-I/P in industrial deployments?
The MCP2140-I/P operates over the industrial temperature range of -40°C to +85°C and features I/O pins compatible with both 3.3 V and 5 V logic levels. This makes it suitable for industrial handheld terminals and embedded controllers where mixed-voltage bus architectures are common.
What procurement considerations apply to the MCP2140-I/P given its YTEOL rating?
With a YTEOL (Years to End-of-Life) rating of 3, the MCP2140-I/P is approaching end-of-life, and buyers should plan last-time buy orders accordingly. The 18-pin PDIP is also a through-hole form factor, which may be phased out faster than SMD variants. Factory lead time is 11 weeks, so securing buffer stock well in advance is strongly recommended for production continuity.
