Frequently Asked Questions
What maximum data rate does the MCP2120-I/SL support over an IrDA infrared link?
The MCP2120-I/SL supports IrDA serial infrared communication at data rates up to 115.2 kbps. It handles all UART-to-IrDA modulation and demodulation internally, so the host microcontroller needs only a standard UART interface without special firmware for IrDA protocol encoding.
How does the MCP2120-I/SL simplify IrDA peripheral integration in portable devices?
By integrating full IrDA modulation and demodulation in a single SOIC-14 device with 14 pins, the MCP2120-I/SL eliminates the need for discrete encoder and decoder components. This reduces BOM count and PCB area in barcode scanners, handheld instruments, and POS terminals requiring short-range infrared data links at up to 115.2 kbps.
When should a designer choose the MCP2120-I/SL over a software IrDA solution in a microcontroller?
A hardware IrDA encoder/decoder like MCP2120-I/SL offloads the timing-critical 115.2 kbps modulation from the MCU, freeing CPU cycles and ensuring precise pulse-width timing without real-time OS overhead. It is preferable in resource-constrained 8-bit systems or when strict IrDA compliance over a 1 m range is required with minimal firmware effort.
