MCP2517FDT-H/JHA

Controllers Overview

The MCP2517FDT-H/JHA is an external CAN FD controller manufactured by Microchip Technology, housed in a 14-pin VQFN package with wettable flanks. It supports arbitration bit rates up to 1 Mbps and data bit rates up to 8 Mbps. The device operates within a supply voltage range of 2.7V to 5.5V and functions at temperatures from -40°C to +150°C. It features a 2 KB message RAM, 31 configurable FIFOs, and 32 flexible filter objects. Communication with the host microcontroller is handled via an SPI interface supporting speeds up to 20 MHz.

Controllers Feature Summary

• Supports CAN FD protocol compliant with ISO 11898-1:2015 alongside CAN 2.0B modes
• Includes 2 KB message RAM protected by Error Correction Code (ECC)
• Provides bus health diagnostics and error counters for monitoring network status
• Features transmit prioritization based on ID or priority fields

Controllers Applications

• Adding CAN FD channels to microcontrollers lacking sufficient peripherals
• Upgrading existing CAN 2.0B systems to CAN FD without MCU replacement
• Industrial automation requiring high-temperature operation

Controllers Procurement Notes

Verify the suffix JHA corresponds to the VQFN14 package with wettable flanks as specified in the datasheet. Confirm the H suffix indicates the extended temperature range of -40°C to +150°C. Ensure the ordering code matches the specific tape and reel configuration required for your assembly process.

Controllers Selection Notes

Select this component when a system requires CAN FD support but the primary MCU lacks native hardware. The VQFN14 package offers a compact footprint suitable for space-constrained designs. Verify that the host SPI interface can handle the required clock speeds and that the GPIO pins are available for interrupt handling.

Controllers Part Context

This part belongs to the MCP2517FD family of external CAN FD controllers. It serves as a bridge between standard microcontrollers and CAN FD networks. The JHA suffix specifically denotes the VQFN14 package variant, distinguishing it from the SOIC14 version found in other model numbers.

Controllers Replacement Considerations

MCP2517FDT-H/SL is a pin-compatible alternative using the SOIC14 package.
