Microchip MCP2140 IrDA Communication Controller Datasheet
The MCP2140 IrDA communication controller implements the IrDA protocol stack, providing UART‑IR encoding/decoding and a low‑cost discrete IR receiver circuit. It operates with a fixed 9600 bps serial and IR interface and supports both DCE and DTE applications in embedded systems.
The device uses a 7.3728 MHz clock source, offers 29‑byte UART and 64‑byte IR buffers, and is available in PDIP, SOIC and SSOP packages. It features hardware handshaking signals (DSR, RTS, CTS) and a low‑power mode consuming less than 1 mA at 3 V. This manual is written in Chinese.
