MCP2542FD in Microchip MCP2515 CAN Family
The MCP2542FD family by Microchip Technology consists of high-speed CAN Flexible Data-rate (CAN FD) transceivers designed to interface a CAN controller with the physical bus. These devices support data rates up to 8 Mbps, effectively buffering between the digital controller and the differential physical layer. They provide critical physical layer features such as loop-back, wake-up patterns, and protection against high-voltage transients, making them a staple in modern automotive and industrial communication networks.
Variants in This Sub-Family
Comparing specs that differ across variants.
| Part Number | Temp Range | Stock |
|---|---|---|
| MCP2542FD-H/SN (Microchip Technology) | -40degC ~ 150degC | 708 |
| MCP2542FD-E/SN (Microchip Technology) | -40degC ~ 125degC | 13,554 |
Variants within the MCP2542FD sub-family are primarily distinguished by their operating temperature ranges and packaging. The 'E' suffix denotes an extended temperature range (-40C to +125C), while the 'H' suffix indicates high-temperature automotive grade performance (-40C to +150C). They are commonly available in 8-lead SOIC or 2x3 DFN packages, allowing designers to balance thermal dissipation requirements against PCB space constraints.
