MCP2518FDT-H/SLVAO

Controllers Overview

The MCP2518FDT-H/SLVAO is a standalone, low-power CAN FD controller manufactured by Microchip Technology. It features an SPI interface for connection to microcontrollers and supports both classic CAN 2.0B and ISO 11898-1:2015 CAN Flexible Data-Rate (CAN FD) protocols. The device operates within a supply voltage range of 2.7 V to 5.5 V and is rated for an extended industrial temperature range of -40°C to +150°C. It provides up to 8 Mbps data bit rate and 1 Mbps arbitration bit rate, housed in a 14-pin SOIC package.

Controllers Feature Summary

• Supports ISO 11898-1:2015 CAN FD protocol alongside classic CAN 2.0B
• Integrated 2 KB message RAM protected by Error Correction Code (ECC)
• Includes 31 configurable FIFOs and 32 flexible filter/mask objects
• Features bus health diagnostics and error counters

Controllers Applications

• Automotive systems requiring high-speed CAN FD communication
• Industrial automation networks with strict temperature requirements
• Microcontroller expansion for devices lacking native CAN FD peripherals

Controllers Procurement Notes

Verify the suffix 'VAO' indicates specific manufacturing or compliance attributes defined by Microchip. Confirm the 'H' grade designation matches the required +150°C maximum operating temperature for your application environment. Ensure the SOIC-14 package footprint aligns with your PCB design constraints.

Controllers Selection Notes

Select this component when an external CAN FD controller is needed for microcontrollers without sufficient internal channels. The H-grade rating is essential for applications exceeding standard industrial temperatures. Compare against the E-grade variant if lower temperature ranges are acceptable, as it may offer different cost structures.

Controllers Part Context

This part belongs to the MCP2518FD family, which succeeded earlier MCP2515 series controllers. The MCP2518FD introduced improvements such as enhanced low-power modes, expanded sequence fields, and dedicated device ID registers. The H/SLVAO designation specifies the high-temperature grade and specific packaging configuration within this lineage.

Controllers Replacement Considerations

The MCP2517FDT-H/SL is listed as an alias for this component but carries a Not Recommended for New Design (NRND) status. Direct replacement should verify pin compatibility and software register mapping differences between the MCP2517 and MCP2518 families.
