MCP2140AT-I/P规格书详情
DEVICE OVERVIEW
The MCP2140A is a cost-effective, low pin count (18-pin), easy-to-use device for implementing IrDA standard wireless connectivity. The MCP2140A provides support for the IrDA standard protocol “stack”, bit encoding/decoding and low cost, discrete IR receiver circuitry. The MCP2140A is footprint compatible with the MCP2140. For migration assistance, please refer to Section 2.14 “Migrating from the MCP2140 to the MCP2140A”.
The serial and IR interface baud rates are fixed at 9600 baud. The serial interface and IR interface baud rates are dependent on the device frequency, but IrDA standard operation requires a device frequency of 3.6864 MHz.
The MCP2140A will specify the IR baud rate to the Primary Device during the Discover phase.
The MCP2140A can operate in Data Communication Equipment (DCE) and Data Terminal Equipment (DTE) applications, and resides between a UART and an infrared optical transceiver.
