MCP2120T-I/SL

Encoders, Decoders, Converters Overview

The MCP2120T-I/SL is a low-cost, high-performance 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 IR optical transceiver, supporting baud rates up to 115.2 kbaud via hardware selection or up to 312.5 kbaud at 20 MHz via software selection. Typical power consumption is less than 1 mA at 3.3V with an 8 MHz clock. It complies with the IrDA Physical Layer Specification version 1.3 and utilizes fully static CMOS technology.

Encoders, Decoders, Converters Feature Summary

• Supports IrDA Physical Layer Specification version 1.3
• Interfaces with any standard UART including 16550 and microcontroller UARTs
• Hardware or software selectable baud rate configuration
• Low power operation with dedicated disable mode

Encoders, Decoders, Converters Applications

• Infrared communication links for portable computing devices
• Wireless data connections using infrared light signaling
• Interfacing microcontrollers with IrDA compliant optical transceivers

Encoders, Decoders, Converters Procurement Notes

Verify the specific suffix 'T' against official documentation to confirm tape and reel packaging requirements. Ensure the component meets the required industrial temperature grade (-40°C to +85°C) and voltage specifications for your application design.

Encoders, Decoders, Converters Selection Notes

Select this component when an IrDA-compliant encoder/decoder is needed between a UART and an optical transceiver. Consider the available clock frequencies and whether hardware or software baud rate control best fits the system architecture. Verify package availability matches the PCB layout constraints.

Encoders, Decoders, Converters Part Context

The MCP2120 series includes variants such as the MCP2120I/SL and MCP2120-IP. These parts share the same core functionality as infrared encoders and decoders but differ in package types like SOIC or PDIP. The MCP2120T-I/SL specifically denotes the industrial temperature grade and likely tape-and-reel packaging format.

Encoders, Decoders, Converters Replacement Considerations

Direct replacements include other MCP2120 variants with compatible packages and temperature ratings. Verify pin compatibility and electrical characteristics before substituting.
