MCP2518FDT-H/QBBVAO

Controllers Overview

The MCP2518FDT-H/QBBVAO is an external CAN FD controller with a Serial Peripheral Interface (SPI) manufactured by Microchip Technology. It supports arbitration bit rates up to 1 Mbps and data bit rates up to 8 Mbps, conforming to ISO 11898-1:2015. The device operates within a supply voltage range of 2.7 V to 5.5 V and features a maximum active current of 20 mA at 5.5 V with a 40 MHz CAN clock. It includes 31 configurable FIFOs, one Transmit Queue, and a Transmit Event FIFO with time stamping. The component is qualified under AEC-Q100 standards for automotive applications.

Controllers Feature Summary

• Supports mixed CAN 2.0B and CAN Flexible Data Rate (CAN FD) communication modes
• Includes Error Correction Code (ECC) protected RAM and SPI commands with CRC for noise detection
• Features three configurable interrupt pins and transceiver standby control capabilities
• Provides bus health diagnostics and error counters for system monitoring

Controllers Applications

• Automotive electronic systems requiring AEC-Q100 qualification
• Microcontrollers lacking integrated CAN FD peripherals
• Industrial automation networks utilizing CAN FD protocols

Controllers Procurement Notes

Verify the specific suffix 'H' indicates the high temperature grade (-40°C to +150°C) and 'QBBVAO' denotes the VDFN package with wettable flanks and automotive qualification. Confirm that the ordering suffix does not alter the functional specifications defined in the datasheet. Ensure compatibility with the required operating voltage and interface timing parameters before procurement.

Controllers Selection Notes

Select this component when an external CAN FD controller is needed for microcontrollers without native support or insufficient channels. The High temperature grade variant is suitable for harsh environments exceeding standard industrial limits. Consider the 2 KB message RAM capacity and FIFO configuration options to meet application buffering requirements.

Controllers Part Context

This part belongs to the MCP2518FD family of external CAN FD controllers. It serves as a cost-effective solution for adding CAN FD capability to existing designs. The device interfaces directly with high-speed CAN FD transceivers without requiring external level shifters when voltages are matched.
