MCP2122-E/SN

Encoders, Decoders, Converters Overview

The MCP2122-E/SN is an infrared encoder/decoder compliant with the IrDA Standard Physical Layer Specification version 1.3. It interfaces a host UART to an IR optical transceiver, supporting baud rates up to 115.2 Kbaud determined by a 16XCLK input. The device operates on a single supply voltage ranging from 1.8V to 5.5V and functions within an extended temperature range of -40°C to +125°C. It features low-power consumption, including a disabled mode drawing 2 µA at 1.8V. The component is housed in an 8-pin SOIC package.

Encoders, Decoders, Converters Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Ensure the procurement channel provides valid traceability for the component. Cross-reference the datasheet revision number to guarantee alignment with current technical specifications before finalizing acquisition.

Encoders, Decoders, Converters Selection Notes

Select this component when interfacing a standard UART with an IrDA-compliant optical transceiver. It requires an external 16XCLK signal to determine the baud rate. Verify that the system power supply falls within the 1.8V to 5.5V range and that the operating environment stays within the specified extended temperature limits.

Encoders, Decoders, Converters Part Context

This part belongs to the MCP212x family of infrared encoder/decoders manufactured by Microchip Technology. It serves as a bridge between digital serial communication protocols and infrared physical layer transmission standards.

Encoders, Decoders, Converters Replacement Considerations

The MCP2122 is pinout-compatible with the Agilent HSDL-7000. Other members of the MCP212x family may offer different baud rate capabilities or additional protocol support such as IrCOMM.
