MCP25625-E/SS

The MCP25625-E/SS is a Microchip high‑speed CAN transceiver. It sits between a CAN controller (e.g., MCP2515) and the CAN bus, handling the physical layer (CANH/CANL) so the controller can send/receive CAN frames.
Key points:
- ISO 11898-2 high‑speed CAN transceiver; supports up to 1 Mbps.
- Supplies: VCC 4.5–5.5 V; GND, CANH, CANL, TXD, RXD, STB (standby), and RS (slew-rate control) pins.
- Bus protection: robust tolerance to fault conditions (typically ±40 V on CANH/CANL), protection against short to supply/ground, overcurrent, thermal shutdown.
- Interface: TXD/RXD to CAN controller; STB for low‑power standby mode; RS adjusts CAN bus edge rate.
- Package: E denotes extended temperature range; /SS indicates the SSOP/SOIC‑8 package option.
- Typical use: pair with a CAN controller like MCP2515 for a complete CAN interface.
Note: It is a transceiver (not a CAN controller) and is often used in automotive/industrial CAN systems.
