Microchip Technology's MCP2551-E/SN CAN Transceiver
The MCP2551-E/SN is a high-speed Controller Area Network (CAN) transceiver, manufactured by Microchip Technology, that serves as an interface between a CAN protocol controller and the physical two-wire CAN bus. This device is designed to provide differential transmit and receive capability to (CAN) communication protocols, conforming to the ISO 11898 standard.
Encased in an 8-pin SOIC (Small Outline Integrated Circuit) package, the MCP2551-E/SN is characterized for operation from -40°C to +125°C, making it suitable for automotive and industrial applications where extreme temperatures are common. The robust design of the MCP2551-E/SN ensures reliable communication in harsh environments, with features that protect against high-voltage transients, loss of ground, and over-temperature conditions.
The transceiver's high-speed operation of up to 1 Mb/s and its ability to operate with a supply voltage range of 4.5V to 5.5V make it versatile for various CAN applications. It also supports up to 112 nodes on a single bus, which is more than sufficient for most network configurations.
Key features of the MCP2551-E/SN include:
- Supports 1 Mb/s operation
- Implements ISO-11898 standard physical layer requirements
- Suitable for 12V and 24V systems
- Externally-controlled slope for reduced RFI emissions
- Protection against high-voltage transients
- Automatic thermal shutdown protection
- Permanent dominant detection
- Power-on reset and voltage brown-out protection
This transceiver is ideal for networking microcontrollers within a vehicle, industrial equipment, and many other CAN bus-based applications. With its reliable performance and protective features, the MCP2551-E/SN from Microchip Technology is a top choice for engineers and developers looking to implement robust CAN communication systems.
