Frequently Asked Questions
What baud rates does the MCP2140A-I/P support for IrDA communication?
The MCP2140A-I/P supports IrDA SIR baud rates from 1.2 kbps up to 115.2 kbps, making it compatible with standard asynchronous serial UARTs operating at 3.3 V or 5 V supply voltage.
Can the MCP2140A-I/P operate in both DTE and DCE modes, and what does that mean for system design?
Yes, the MCP2140A-I/P supports both DTE (Data Terminal Equipment) and DCE (Data Communications Equipment) modes. This dual-mode capability allows designers to interface the IC with a wide range of devices without additional logic, reducing BOM count and simplifying PCB layout for the 18-pin PDIP footprint.
How does the MCP2140A-I/P compare to a software IrDA stack implementation in terms of resource usage?
The MCP2140A-I/P offloads IrDA framing and encoding entirely in hardware, freeing the host MCU from handling timing-critical 115.2 kbps bit manipulation. This results in lower CPU load, deterministic latency under 1 µs pulse-width encoding, and eliminates the need for a dedicated software IrDA library.
What package does MCP2140A-I/P use and how many pins does it have?
The MCP2140A-I/P comes in an 18-pin PDIP (Plastic Dual In-Line Package) with 0.3-inch row spacing, suitable for through-hole PCB assembly and breadboard prototyping in industrial and consumer designs.
