The PCA82C250/N4 is a stand-alone Controller Area Network (CAN) controller interface from NXP Semiconductors, designed for high-speed automotive and industrial communication networks. This robust device provides an interface between a CAN protocol controller and the physical two-wire CAN bus, and is designed to operate at speeds of up to 1 Mbit/s.

Key Features

• High-Speed CAN Interface: Supports the ISO 11898 standard up to 1 Mbit/s.
• Low-Power Mode: An important feature that allows the device to consume minimal power in idle or standby states, making it suitable for power-sensitive applications.
• Differential Receiver with Wide Common-Mode Range: Ensures reliable data transmission and reception over the CAN bus, even in environments with high electrical noise.
• Thermal Protection: Integrated thermal protection circuitry ensures the device operates within safe temperature ranges, preventing damage from overheating.
• Short-Circuit Resistant: The driver output stages are protected against short-circuit conditions, enhancing the longevity and reliability of the interface.
• Compatibility: The PCA82C250/N4 is compatible with the "non-return to zero" (NRZ) data format used in CAN networks.
