Product Overview

The MCP2120-I/SL is a low-cost high-performance fully-static Infrared Encoder/Decoder sits between an UART and an infrared (IR) optical transceiver. The data received from a standard UART is encoded (modulated) and output as electrical pulses to the IR transceiver. The IR transceiver also receives data which it outputs as electrical pulses that the MCP2120 decodes (demodulates) then transmits the data via the MCP2120 UART. This modulation and demodulation method is performed in accordance with the IRDA standard. Typically a microcontroller interfaces to the IR encoder/decoder. Infrared communication is a wireless two-way data connection using infrared light generated by transceiver signalling technology. This provides reliable communication between two devices.
  • Maximum baud rate can run up to 312.5kbaud with higher frequency clock input
  • Supports with IrDA® physical layer specification (version 1.3)
  • 1.63µs Transmit/receive formats supported
  • Low-power, high-speed CMOS technology - fully static design
