NXP Semiconductors TJA1152 / TJA1153

• TJA1152: Secure HS-CAN transceiver with Standby mode
• TJA1153: Secure HS-CAN transceiver with Sleep mode
   

New secure CAN transceiver TJA115x provides a seamless and very cost-effective solution for securing classical CAN and CAN FD communication without cryptography.

It provides an interface between a classical CAN or CAN FD protocol controller and the physical two-wire CAN bus.

Key features

• Secure HS-CAN transceiver with Sleep mode (TJA1152) / Stand by mode (TJA1153)
• Supporting high-speed CAN and CAN FD up to 2 Mbit/s
• Available in SO8 or HVSON14 packages
• Detection and containment of following security incidents: – Flooding/Tampering/Spoofing

Additional features

General

• TJA1152A is a secure HS-CAN transceiver with Standby mode & a VIO supply pin.
• TJA1153A is a secure HS-CAN transceiver with Sleep mode & a VIO supply pin.
• The VIO pin allows for direct interfacing with 3.3 V & 5 V microcontrollers
• ISO 11898-1:2015, ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 compliant
• Operates in classical CAN and CAN FD systems with arbitration phase bit rate set at 125 kbit/s, 250 kbit/s or 500 kbit/s
• For arbitration bit rates of 250 kbit/s and 500 kbit/s, the fast phase bit rate can be set to two or four times the arbitration bit rate
• AEC-Q100 (G) qual (grade 1)
• Low EME & high EMI
• TJA1152 : SO8 plastic package
• TJA1153 : HVSON14 plastic package
