1. Describe
MCP2562-E/MF is Microchip Technology Inc.'s second-generation high-speed CAN transceiver. It acts as the interface between the CAN protocol controller and the physical two-wire CAN bus. The device meets the high speed (up to 1Mb/s), low quiescent current, electromagnetic compatibility (EMC) and electrostatic discharge of automobiles.
Device Description
MCP2562-E/MF is a high-speed CAN fault-tolerant device used as an interface between the CAN protocol controller and the physical bus. The MCP2561/2 device provides differential transmit and receive functions for the CAN protocol controller, and is fully compatible with ISO-11898-2 and ISO-11898-5 standards. It will run at speeds up to 1Mb/s. Generally speaking, each node in the CAN system must have a device to convert the digital signal generated by the CAN controller into a signal suitable for transmission through the bus cable (differential output). It also provides a buffer between the CAN controller and the high voltage spikes generated by the external source on the CAN bus.
2. Feature
1. Support 1Mb/s operation
2. Implement ISO-11898-2 and ISO-11898-5
- Standard physical layer requirements
3. Very low standby current (5μA, typical value)
4. The VIO power pin is directly connected to
- CAN controller and microcontroller
- 1.8V to 5.5V input/output
5. Independent output pins for stabilizing common mode in the biased split termination scheme
6. The CAN bus pin is disconnected when the device is powered off
- Unpowered nodes or power-down events will not load the CAN bus
7. Ground fault detection:
- Permanent public inspection on TXD
- Permanent public detection on the bus
8. Power-on reset and voltage power-down protection on VDD pin
9. Prevent damage caused by short circuit conditions (battery positive or negative voltage)
10. Prevent high voltage transients in the automotive environment
11. Automatic thermal shutdown protection
12. Suitable for 12V and 24V systems
13. Meet or exceed stringent automotive design requirements, including "Hardware Requirements for LIN, CAN and FlexRay Interfaces in Automotive Applications", Version 1.3, May 2012
14. Due to the use of differential bus to achieve high noise immunity
15. High Electrostatic Discharge (ESD) protection for CANH and CANL, in accordance with IEC61000-4-2 up to ±14kV
16. Provide PDIP-8L, SOIC-8L and 3x3DFN-8L
17. temperature range:
- Extended (E): -40°C to +125°C
- High (H): -40°C to +150°C
