MCP2561-E from Microchip Tech, in a PDIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | TXD | input | Transmitter data input: Low puts CANH and CANL in the Dominant state and High in the Recessive state, with an internal pull-up of nominal 33 k to VDD on the MCP2561. |
| 2 | VSS | power_in | Ground supply pin. |
| 3 | VDD | power_in | Positive supply voltage pin that supplies the transmitter and receiver, including the wake-up receiver; the typical undervoltage threshold on VDD is 4 V. |
| 4 | RXD | output | CMOS-compatible receive data output that is High when the CAN bus is Recessive and Low when it is Dominant, supplied by VDD on the MCP2561. |
| 5 | SPLIT | output | Reference voltage output defined as VDD/2 that is active only in Normal mode and floats in Standby mode or when VDD is off (MCP2561 only). |
| 6 | CANL | bidirectional | CAN Low-level voltage I/O that drives the Low side of the differential bus and disconnects from the bus when the device is not powered. |
| 7 | CANH | bidirectional | CAN High-level voltage I/O that drives the High side of the differential bus and disconnects from the bus when the device is not powered. |
| 8 | STBY | input | Standby mode input: Low selects Normal mode and High selects Standby mode, with an internal MOS pull-up to VDD whose typical value is 660 k at 5 V. |
