CAN 2.0B Bus Controller IP Core

Overview

Key Features

• ASIL-C, ISO26262 Certified, Automotive Grade
• * Implements CAN2.0A and CAN2.0B protocol, ISO 11898-1 compliant
• Supports CAN-FD
• * Non-ISO CAN FD – Compliant to Bosch Protocol
• * Independent System Clock(SYSCLK) and CAN Bus Clock(CANCLK)
• * SYSCLK is CPU interface Bus Clock, – AHB Clock in case of ARM
• * CANCLK can either be independent or tied to SYSCLK
• * Flexible shared buffering scheme that implements optimal buffer size for Transmit and Receive messages
• * Total buffer size is parameterized – synthesis time option
• * Buffer can be implemented as a single port SRAM or flops
• * Transmit buffer, receiver buffer and high-priority transmit buffer
• * CPU configurable depths for transmit, receive and high-priority transmit buffers
• * Parameterized number of Acceptance Filters – 1-16
• * AHB-Lite Slave Interface for connecting to CPU
• * Optional APB Interface
• * Supports 32-bit interface
• * Programmable Baud Rate Prescalar (BRP)
• * Generate Time Quantum Clock from CANCLK
• * 8-bit BRP register to have div-by-2 up to div-by-255
