MCP2518FDT-E/SL

Controllers Overview

The MCP2518FDT-E/SL is an external CAN FD controller manufactured by Microchip Technology, designed to add CAN FD channels to microcontrollers lacking sufficient peripherals. 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 on a supply voltage of 2.7V to 5.5V with a maximum active current of 20 mA at 5.5V and 40 MHz CAN clock. It features 31 configurable FIFOs, one Transmit Queue (TXQ), and 32 flexible filter/mask objects. Communication with the host MCU occurs via an SPI interface supporting speeds up to 20 MHz in Modes 0 and 3. The component is housed in a 14-SOIC package and is qualified to AEC-Q100 standards for automotive applications.

Controllers Feature Summary

• Supports mixed CAN 2.0B and CAN FD modes with programmable automatic retransmission attempts.
• Includes 2 KB of ECC-protected message RAM and 32 flexible filter and mask objects for precise message filtering.
• Features low power consumption with a typical sleep current of 15 µA and a maximum low power mode current of 10 µA across the full temperature range.
• Provides bus health diagnostics, error counters, and transceiver standby control capabilities.

Controllers Applications

• Adding CAN FD communication capability to microcontrollers that lack native CAN FD peripherals or have insufficient channel counts.
• Automotive electronic systems requiring AEC-Q100 qualified components for robust network communication.
• Industrial control systems utilizing CAN FD protocols for high-speed data transmission between devices.

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and temperature grade. Confirm that the required quantity matches the standard packaging options available from authorized distributors. Ensure compliance with RoHS directives if applicable to your manufacturing process. Cross-reference the datasheet revision number to guarantee compatibility with existing design specifications.

Controllers Selection Notes

Select this component when a system requires external CAN FD support via SPI interface. Ensure the host microcontroller can provide the necessary SPI clock speed and interrupt handling. Verify that the operating voltage range of 2.7V to 5.5V aligns with the system power rails. Consider the 14-SOIC package dimensions for PCB layout constraints and thermal management requirements during the design phase.

Controllers Part Context

The MCP2518FD belongs to the MCP2515 family of CAN controllers but introduces significant enhancements such as CAN FD support and improved power management. It serves as a successor to earlier CAN controllers by offering higher data rates and additional memory resources. The device is part of Microchip's portfolio aimed at providing cost-effective solutions for expanding CAN network capabilities in embedded systems.
