MCP2518FDT-E/QBBVAO

Controllers Overview

The MCP2518FDT-E/QBBVAO is an external CAN FD controller with a Serial Peripheral Interface (SPI). It supports arbitration bit rates up to 1 Mbps and data bit rates up to 8 Mbps. The device operates within a voltage range of 2.7 V to 5.5 V, with a maximum active current of 20 mA at 5.5 V and a typical sleep current of 15 µA. It features 31 configurable FIFOs, one Transmit Queue, and a Transmit Event FIFO. The package is a 14-pin VDFN with wettable flanks.

Controllers Feature Summary

• Supports mixed CAN 2.0B and CAN FD modes conforming to ISO 11898-1:2015
• Includes 31 configurable message FIFOs and 32 flexible filter objects
• Features ECC protected RAM and SPI commands with CRC for noise detection
• Provides transceiver standby control and bus health diagnostics

Controllers Applications

• Adding CAN FD channels to microcontrollers lacking sufficient peripherals
• Automotive electronic systems requiring AEC-Q100 qualified components
• Industrial automation networks utilizing CAN FD protocol

Controllers Procurement Notes

Verify the specific suffix 'QBBVAO' against official Microchip documentation to confirm package type and qualification status. Ensure compatibility with system voltage requirements and temperature ranges before procurement.

Controllers Selection Notes

Select this component when a microcontroller requires additional CAN FD connectivity via SPI. Consider the 14-VDFN package size and thermal pad requirements for PCB layout. Verify that the host processor supports the required SPI clock speeds and modes.

Controllers Part Context

This part belongs to the MCP2518FD family of external CAN FD controllers. It serves as a cost-effective solution for expanding CAN network capabilities in embedded systems where integrated CAN peripherals are insufficient or unavailable.

Controllers Replacement Considerations

Check for direct pin-compatible alternatives within the MCP2518FD series. Verify functional equivalence regarding FIFO counts, filter configurations, and power consumption specifications.
