MCP2561T-E/SN

• T = Tape-and-reel bulk packaging
• E = Extended industrial temperature grade
• SN = 8-pin narrow SOIC surface-mount package (3.9mm width)
• Core distinction vs MCP2562FD: Equipped with SPLIT pin instead of VIO level-shift pin, only supports standard CAN 2.0 up to 1 Mbps (no CAN FD high-speed phase)

1. CAN Standard & Communication Performance

• Fully compliant with ISO 11898-2 (high-speed CAN) and ISO 11898-5 (low-power CAN standby)
• Maximum bit rate: 1 Mbps for CAN 2.0A/B frames only; CAN FD 2/8 Mbps high-speed mode is unsupported
• SPLIT dedicated pin: Outputs stabilized 0.5×VDD common-mode bias voltage for split termination networks, optimizing EMC noise suppression on long twisted-pair CAN bus cables
• Differential transmit/receive topology to reject industrial common-mode interference

2. Power & Low-Power Standby Functions

• Main VDD supply range: 4.5 V ~ 5.5 V, matching 12 V / 24 V automotive and industrial power rails
• Two operating modes: Normal communication mode + ultra-low-power Standby mode
• Standby quiescent current: Typical 5 µA, minimizing battery drain for parked vehicle or idle sensor nodes
• Remote wake-up trigger via CAN bus traffic when in standby state
• Critical bus isolation: Unpowered transceiver nodes cannot pull down the entire CAN bus network

3. Comprehensive Built-In Fault Protection

• Permanent dominant timeout lockout on TXD pin: Prevents total bus stall caused by MCU software crash
• Cycle-by-cycle thermal shutdown with auto-recovery to avoid overheating damage
• VDD undervoltage lockout (UVLO): Blocks invalid bus transmission during supply voltage fluctuations
• Short-circuit protection for CANH / CANL differential bus lines
• High surge tolerance: CAN bus pins withstand ±40 V transient voltage surges; ±14 kV IEC 61000-4-2 contact ESD protection for harsh wiring environments

4. Electrical & Environmental Ratings

• Operating temperature range (E extended grade): -40°C to +125°C automotive industrial wide temperature range
• Typical normal-mode supply current: 45 mA; peak current limited to 70 mA
• Tingkat sensitivitas kelembapan (MSL) 3 (masa simpan di lantai selama 168 jam sebelum proses penyolderan reflow)
• Fully RoHS lead-free and halogen-free compliant
• Standard tape-and-reel packaging (T suffix) for high-volume automated SMT assembly

5. Package Specifications

• Package type: 8-pin narrow-body SOIC (SOIC-8) surface mount, compact footprint for small CAN interface add-on boards
• Pin layout: VDD, VSS, RXD, CANH, CANL, SPLIT, STBY, TXD (no separate VIO logic level supply pin)
