Mcp25625t-e / ml qfn28 can interface IC
describe
Mcp25625 is a complete, cost-effective and small space can solution, which can be easily added to the microcontroller with available SPI interface.
Mcp25625 interfaces directly with microcontrollers operating between 2.7V and 5.5V; No external level converter is required. In addition, mcp25625 is directly connected to the physical can bus and supports all requirements for can high-speed transceiver.
Mcp25625 meets the requirements of automobile for high speed (up to 1MB / s), low quiescent current, electromagnetic compatibility (EMC) and electrostatic discharge (ESD).
General characteristics
