MCP2518FDT-H/QBB

Controllers Overview

The MCP2518FDT-H/QBB is an external CAN FD controller manufactured by Microchip Technology, designed for integration with microcontrollers via 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 and features a maximum active current of 20 mA at 5.5 V with a 40 MHz CAN clock. It includes 2 KB of message RAM protected by Error Correction Code (ECC) and offers 31 configurable FIFOs. The component is qualified under AEC-Q100 standards and functions reliably in the extended temperature range of -40°C to +150°C.

Controllers Feature Summary

• Supports mixed CAN 2.0B and CAN FD modes compliant with ISO 11898-1:2015
• Includes SPI commands with CRC for noise detection on the interface
• Features low power mode reducing leakage current to 10 µA across full temperature range
• Provides bus health diagnostics and error counters

Controllers Applications

• Adding CAN FD channels to microcontrollers lacking sufficient peripherals
• Automotive electronic control units requiring high reliability
• Industrial automation systems needing robust communication interfaces

Controllers Procurement Notes

Verify the specific ordering suffixes against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with system voltage levels and SPI timing requirements before finalizing procurement decisions.

Controllers Selection Notes

Select this component when a standalone CAN FD controller is required alongside an existing MCU. Consider the H-grade temperature rating for environments exceeding standard industrial limits. Verify that the target application can accommodate the VDFN14 package dimensions and thermal pad requirements.

Controllers Part Context

This part belongs to the MCP2518FD family, which improves upon previous generations by adding a Low Power Mode and expanding the SEQ field. It utilizes a saw-cut DFN package with wettable flanks for improved solderability. The DEVID register allows differentiation between future members of the device series.
