Product Overview: MCP2122T-E/SN from Microchip Technology
The MCP2122T-E/SN is a versatile and efficient infrared (IrDA) serial encoder/decoder device developed by Microchip Technology. This product is designed to facilitate infrared data communication by integrating modulation and demodulation of infrared signals in compliance with the IrDA standard. The MCP2122T-E/SN operates as a serial-to-IrDA Standard Encoder/Decoder, making it an ideal choice for applications requiring wireless infrared data transfer.
Encased in an 8-pin SOIC (Small Outline Integrated Circuit) package, the MCP2122T-E/SN is compact and suitable for space-constrained applications. It boasts a baud rate from 9600 to 115.2k baud (bits per second), providing flexibility for various communication requirements. The device operates at a nominal supply voltage of 3.3V, which is conducive to low-power consumption, making it particularly well-suited for battery-powered devices.
One of the key features of the MCP2122T-E/SN is its compatibility with the IrDA physical layer standard, which ensures interoperability with other IrDA-compliant devices. Additionally, it includes an on-board oscillator which can be configured with external resistors, eliminating the need for an external crystal, thereby reducing the overall bill of materials for the end product.
The MCP2122T-E/SN is also equipped with a host of other features such as a shutdown pin for power-saving mode, carrier frequency of 38kHz, and an LED driver circuit which can directly drive an infrared emitting diode. These features make the device not only power-efficient but also user-friendly for designers and engineers looking to incorporate infrared communication capability into their systems.
Typical applications for the MCP2122T-E/SN include wireless infrared data links, personal data assistants (PDAs), mobile phones, data loggers, and any other devices requiring short-range, line-of-sight infrared data communication. The device's robust design and Microchip's commitment to quality make it a reliable choice for both commercial and industrial applications.
Overall, the MCP2122T-E/SN by Microchip Technology represents a compact, reliable, and cost-effective solution for adding infrared data communication to a wide array of electronic products.
