Specifications
MCP2562FD-E/SN is a second-generation high-speed CAN FD physical layer transceiver manufactured by Microchip Technology. Suffix breakdown:
- FD = Supports CAN Flexible Data Rate protocol
- E = Extended industrial temperature grade
- SN = 8-pin narrow SOIC (3.90mm width) surface-mount package
1. Core CAN FD Communication Specifications
- Compliant with ISO 11898-2 (high-speed CAN) and ISO 11898-5 (low-power CAN) standardsMicrochip Technology
- Dual-rate operation:
- Classical CAN: Up to 1 Mbps
- CAN FD fast data phase: Max 8 Mbps
- Optimized loop delay symmetry to guarantee stable high-speed CAN FD transmission on long bus cables
- Max propagation delay ≤ 120 ns, compatible with extended cable topologies in factory and vehicle systems
2. Unique VIO Level-Shifting Interface
Integrated separate VIO supply pin supporting 1.8 V ~ 5.5 V logic I/O, enabling direct connection to 1.8 V / 2.5 V / 3.3 V MCUs, DSPs and CAN controllers without external level shift resistorsMicrochip Technology.
VDD bus supply fixed at 4.5 V ~ 5.5 V for 12 V / 24 V automotive and industrial power systems.
3. Low-Power Standby & Wake-Up Functions
- Ultra-low standby quiescent current: Typical 5 μA, minimizes battery static drain for idle network nodes
- Remote wake-up via CAN bus traffic in standby mode
- Automatic bus disconnection when the device loses VDD power; unpowered nodes will not pull down the entire CAN bus networkMicrochip Technology
4. Comprehensive Built-In Protection Mechanisms
- Permanent dominant timeout protection on TXD pin to avoid bus lock-up from MCU software crash
- Cycle-by-cycle thermal shutdown auto-recovery for overheat protection
- Undervoltage lockout (UVLO) on VDD supply to block invalid bus transmission during power fluctuation
- Short-circuit protection for CANH/CANL bus lines
- High ESD robustness: ±14 kV contact discharge (IEC 61000-4-2) on CAN bus pins for harsh industrial wiring environments
5. Electrical & Environmental Ratings
- Operating temperature range (E grade): -40°C to +125°C industrial wide temperature range
- Normal operating supply current: 45 mA typical; peak limited to 70 mA
- MSL 3 moisture sensitivity level (168-hour floor life before reflow soldering)
- Fully RoHS lead-free and halogen-free compliant
- Standard tube packaging; tape-and-reel variant MCP2562FDT-E/SN available for mass SMT production lines
6. Package Information
- Package: 8-pin narrow-body SOIC (SOIC-8, 0.154″ width) surface mount
- Small footprint for compact CAN interface add-on boards, sensor modules and embedded control units
