MCP2120-I/P

Encoders, Decoders, Converters Overview

The MCP2120-I/P is a low-cost, fully-static infrared encoder/decoder manufactured by Microchip Technology. It operates within a supply voltage range of 2.5V to 5.5V and supports industrial temperature ranges from -40°C to +85°C. The device interfaces between a UART and an IrDA-compliant optical transceiver, supporting baud rates up to 115.2 kbaud via hardware selection or 312.5 kbaud at 20 MHz via software selection. Typical current consumption is less than 1 mA at 3.3V with an 8 MHz clock, and approximately 3 mA when disabled at 5.0V. It utilizes a 14-pin PDIP package.

Encoders, Decoders, Converters Procurement Notes

Verify the specific suffix 'I/P' corresponds to the Industrial temperature grade (-40°C to +85°C) and the 14-pin Plastic Dual In-line Package (PDIP). Confirm that the ordering part number matches the exact datasheet revision required for your design. Ensure compatibility with the intended IrDA transceiver module before finalizing procurement.

Encoders, Decoders, Converters Selection Notes

Select this component when an IrDA-compliant physical layer interface is required between a microcontroller UART and an optical transceiver. Consider the hardware versus software baud rate selection requirements based on system flexibility needs. Evaluate the power consumption specifications against battery life requirements, noting the low-power mode capabilities available through the EN pin control.

Encoders, Decoders, Converters Part Context

The MCP2120 is part of Microchip's infrared communication product line designed to simplify IrDA implementation. It eliminates the need for complex external modulation and demodulation circuitry by integrating these functions into a single static CMOS chip. This allows designers to focus on higher-level protocol implementation while relying on the MCP2120 for reliable physical layer signaling compliant with industry standards.
