Product details
Overview
TJA1463ATK/0Z from NXP Semiconductors is a CAN FD signal improvement transceiver with Sleep mode, implementing ISO 11898-2:2024 parameter set C for reduced signal ringing and supporting up to 8 Mbit/s data rates. It features VIO input for 3.3 V–5 V microcontroller interfacing, AEC-Q100 Grade 1 qualification, and HVSON14 (3.0 mm × 4.5 mm) leadless package. Used in automotive body control modules for reliable high-speed CAN FD communication in large topologies.
For engineers reviewing the TJA1463ATK/0Z datasheet, TJA1463ATK/0Z pinout, TJA1463ATK/0Z application, or TJA1463ATK/0Z equivalent, key selection criteria include CAN FD SIC compliance, ultra-low Sleep mode current (≤26 µA), dual wake-up capability (bus/local/host), fail-safe undervoltage behavior, and pin compatibility with legacy transceivers like TJA1043.
Technical Context
The TJA1463ATK/0Z integrates two independent state machines - system and CAN - enabling gap-free operation across supply voltage transitions and robust fail-safe behavior during undervoltage events. Its CAN Signal Improvement Capability (SIC) actively suppresses reflections via optimized driver symmetry and bus biasing, directly enabling stable 8 Mbit/s CAN FD in electrically challenging topologies.
It supports five system modes (Off, Standby, Normal, Listen-only, Sleep) controlled by STB_N and EN pins, with defined transitions and ERR_N flag reporting. The CAN state machine operates six modes (e.g., CAN Active, CAN Listen-only, CAN Wake), where bus biasing shifts between GND (Offline/Wake) and VCC/2 (Active/Listen-only) to ensure deterministic receiver operation and transmitter safety.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Battery supply voltage (VBAT) | 4.5 V to 28 V operating range - supports full automotive battery transient profile without external regulation. |
| Sleep mode current (IBAT) | 13 µA to 26 µA - enables multi-year battery life in always-on vehicle domains requiring periodic CAN wake-up. |
| CAN FD data rate | Up to 8 Mbit/s - enabled by tighter bit timing symmetry and SIC, exceeding standard CAN FD transceivers limited to 5 Mbit/s. |
| Wake-up pattern filter time | 0.5 µs to 1.8 µs - meets ISO 11898-2:2024 requirements for both Classical CAN and CAN FD bus wake-up detection. |
| ESD tolerance (CANH/CANL) | ±6 kV per IEC 61000-4-2 - eliminates need for external TVS diodes in most automotive PCB layouts. |
| Operating temperature | −40 °C to +150 °C virtual junction - qualified to AEC-Q100 Grade 1, suitable for under-hood and powertrain applications. |
| VIO supply range | 2.95 V to 5.5 V - allows direct interface with 3.3 V or 5 V microcontrollers without level shifters. |
Pinout & Package
Package: HVSON14 (3.0 mm × 4.5 mm × 0.85 mm), thermally enhanced leadless package with exposed center pad (GND-connected); supports automated optical inspection (AOI) and improved thermal dissipation vs. SO14.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TXD (1) | Transmit data input | Digital input from CAN controller; drives bus only in Normal mode; dominant timeout disables transmitter if held LOW > tto(dom)TXD. |
| GND (2) | Ground reference | Primary die supply ground; must be soldered to PCB ground; exposed center pad also connected to GND for thermal/electrical integrity. |
| VCC (3) | 5 V logic supply | Supplies internal logic and receiver; undervoltage detection (4 V–4.5 V) triggers mode transition to Standby/Sleep. |
| RXD (4) | Receive data output | Digital output to CAN controller; reflects bus state in all active modes; held LOW after wake-up to indicate source. |
| VIO (5) | I/O voltage adapter | Sets logic levels for TXD/RXD/STB_N/EN/ERR_N; enables direct connection to 3.3 V or 5 V MCUs without level translation. |
| EN (6) | Enable control input | Active-HIGH; selects Normal (EN=HIGH, STB_N=HIGH) or Listen-only (EN=LOW, STB_N=HIGH) mode. |
| INH (7) | Inhibit output | Active-HIGH analog output; controls external voltage regulators; floats high-ohmic in Sleep mode to disable downstream supplies. |
| ERR_N (8) | Failure/wake-up flag output | Active-LOW open-drain; reports Pwon, Wake, Wake-up source, or Local failure flags depending on system mode. |
| WAKE (9) | Local wake-up input | Analog input; detects logic-level change with ≥twake stability; initiates wake-up from Standby/Sleep without VCC/VIO present. |
| VBAT (10) | Battery supply input | Primary power domain; powers low-power wake-up receiver; undervoltage (4 V–4.5 V) forces Off mode and cold-start detection. |
| n.c. (11) | No connect | Internally unconnected terminal; no PCB trace or solder required. |
| CANL (12) | CAN bus low line | Analog I/O; differential pair with CANH; protected to ±40 V; biased to GND in Offline/Wake, VCC/2 in Active/Listen-only. |
| CANH (13) | CAN bus high line | Analog I/O; differential pair with CANL; same protection and biasing as CANL; SIC reduces ringing during edge transitions. |
| STB_N (14) | Standby control input | Active-LOW; primary mode selector - LOW forces Standby/Sleep regardless of EN; rising edge wakes device if VIO valid. |
Key Features
| Feature | Design Value |
|---|---|
| CAN Signal Improvement (SIC) | Reduces signal ringing per ISO 11898-2:2024 parameter set C, enabling reliable 8 Mbit/s CAN FD in daisy-chain or branched topologies > 20 m. |
| Triple wake-up sources | Supports local (WAKE pin), bus (CANH/CANL pattern), and host (STB_N/EN) wake-up - allows full node power-down while retaining responsiveness. |
| Fail-safe undervoltage handling | Defined behavior across VBAT/VCC/VIO thresholds; transceiver disengages bus (high-ohmic) below Vuvd(VBAT); ERR_N flags cause of reset. |
| Integrated diagnostics | Four internal flags (Pwon, Wake, Wake-up source, Local failure) accessible via ERR_N - enables autonomous fault isolation without MCU polling overhead. |
| Listen-only mode | Receiver active, transmitter disabled - permits non-intrusive network monitoring and failure containment during diagnostic sessions. |

FAQ
What is the maximum CAN FD data rate supported by the TJA1463ATK/0Z?
The TJA1463ATK/0Z supports CAN FD communication up to 8 Mbit/s, enabled by tighter bit timing symmetry and integrated Signal Improvement Capability (SIC) per ISO 11898-2:2024 parameter set C. This exceeds the 5 Mbit/s limit of standard CAN FD transceivers and is validated for use in electrically noisy, extended-topology automotive networks.
Does the TJA1463ATK/0Z require external level shifters when interfacing with a 3.3 V microcontroller?
No. The TJA1463ATK/0Z includes a dedicated VIO pin that accepts 2.95 V to 5.5 V, automatically adapting the logic levels of TXD, RXD, STB_N, EN, and ERR_N to match the connected microcontroller. This eliminates external level shifters when interfacing with 3.3 V or 5 V MCUs.
How does the TJA1463ATK/0Z handle undervoltage conditions on VBAT, VCC, or VIO?
The TJA1463ATK/0Z implements independent undervoltage detection on VBAT (4–4.5 V), VCC (4–4.5 V), and VIO (2.65–2.95 V). Below threshold, it transitions predictably to Standby or Sleep mode, disengages the bus (high-ohmic), and reports cause via ERR_N flags - ensuring fail-safe behavior without MCU intervention.
Can the TJA1463ATK/0Z be used as a direct replacement for the TJA1043 in an existing design?
Yes - the TJA1463ATK/0Z is pin-compatible with the TJA1043 in HVSON14 package and requires no hardware or software changes. It retains identical pin functions and electrical behavior in Normal mode while adding SIC, higher speed, lower Sleep current, and enhanced diagnostics - enabling seamless retrofitting.
What wake-up sources does the TJA1463ATK/0Z support, and how is wake-up source identification implemented?
The TJA1463ATK/0Z supports local (WAKE pin), bus (CANH/CANL pattern), and host (STB_N/EN) wake-up. Wake-up source identification is implemented via the Wake-up source flag, reported on ERR_N in Normal mode: LOW indicates local wake-up or power-on, HIGH indicates remote (bus) wake-up - enabling precise root-cause analysis in diagnostics.
