MCP25625-E/SS

The MCP25625-E/SS is an 8‑pin, 5V high‑speed CAN transceiver from Microchip. It sits between a CAN controller (e.g., MCP2515) and the CAN bus, providing the physical layer: translating the controller’s TXD/RXD signals to the differential CANH/CANL bus and supplying the proper bus biasing for recessive/dominant states.
Key points:
- CAN physical layer device: CANH/CANL, Vcc, GND, TXD and RXD signals.
- Data rate: up to 1 Mbps; suited for automotive/industrial CAN networks.
- Protections and modes: fault protection, undervoltage/short‑circuit protection, ESD protection, standby/normal operation for low power.
- Packaging and temp: “E” indicates extended operating temperature (-40°C to +125°C). “SS” denotes the RoHS, small‑outline package (SOIC/SSOP style).
Usage:
- Pair with a CAN controller (e.g., MCP2515). Connect TXD/RXD to the controller and CANH/CANL to the CAN bus. Provide Vcc and GND; use standby as needed.
In short: it’s the robust physical layer for CAN networks, not a controller itself, and is designed for harsh environments with extended temperature packaging.
