MCP2155-I/SO

The MCP2155-I/SO from Microchip Technology is a cost-effective, low pin count device designed for implementing IrDA standard wireless connectivity. It handles the IrDA protocol stack and bit encoding/decoding, interfacing between a UART and an infrared optical transceiver. This controller supports Data Communication Equipment (DCE) applications.

Key electrical specifications include an operating voltage range of 3V to 5.5V and a typical current consumption of 7mA. The device supports various UART baud rates from 9.6 kbaud to 115.2 kbaud, and infrared baud rates from 9.6 kbaud to 115.2 kbaud. It features a 64-byte data packet size and operates within an industrial temperature range of -40°C to 125°C.

The MCP2155-I/SO is available in an 18-SOIC package, suitable for surface mounting. Its design utilizes low-power, high-speed CMOS technology, offering a fully static design and low voltage operation. The device also includes features like a programmable device ID string and operates as a secondary device.

This controller is ideal for applications requiring IrDA communication, such as point-of-sale terminals, mobile devices, and industrial communication systems where wireless infrared data transfer is needed.
