The MCP2140AT-I/SO from Microchip Technology is a cost-effective, low pin count device designed for implementing IrDA standard wireless connectivity. It supports the IrDA standard protocol stack, including bit encoding/decoding, and low-cost discrete IR receiver circuitry. The device features a UART interface for connecting to DCE or DTE systems and provides IrDA standard physical signal layer support.
Key electrical specifications include a wide operating voltage range of 2.0V to 5.5V and an operating current of 2.2mA. The operating temperature range is industrial, from -40°C to 125°C. The serial and IR interface baud rates are fixed at 9600 baud. It also includes an automatic low power mode with consumption less than 23 µA when no IR activity is present.
This controller is housed in an 18-SOIC package, measuring 0.295" (7.50mm) in width. It is footprint compatible with the MCP2140. The device implements IrDA protocols such as IrLAP, IrLMP, and IAS, and provides CRC implementation.
It is suitable for applications requiring wireless infrared communication, interfacing standard UARTs with infrared transceivers.
