CAN Controller with Integrated Transceiver
General Features:
CAN Transceiver Features:
• Stand-Alone CAN2.0B Controller with Integrated
CAN Transceiver and Serial Peripheral
Interface (SPI)
• VDDA: 4.5V to 5.5V
• Implements ISO-11898-2 and ISO-11898-5
Standard Physical Layer Requirements
• Up to 1 Mb/s Operation
• CAN Bus Pins are Disconnected when Device is
Unpowered
• Very Low Standby Current (10 µA, typical).
• Up to 10 MHz SPI Clock Speed
- An Unpowered Node or Brown-Out Event will
not load the CAN bus
• Interfaces Directly with Microcontrollers with 2.7V
to 5.5V I/O
• Detection of Ground Fault:
• Available in SSOP-28L and 6x6 QFN-28L
• Temperature Ranges:
- Permanent dominant detection on TXD
- Permanent dominant detection on bus
- Extended (E): -40°C to +125°C
• Power-on Reset and Voltage Brown-Out
Protection on VDDA Pin
• Protection Against Damage Due to Short-Circuit
Conditions (Positive or Negative Battery Voltage)
CAN Controller Features:
• VDD: 2.7 to 5.5V
• Protection Against High-Voltage Transients in
Automotive Environments
• Implements CAN 2.0B (ISO11898-1)
• Three Transmit Buffers with Prioritization and
Abort Feature
• Automatic Thermal Shutdown Protection
• Suitable for 12V and 24V Systems
• Two Receive Buffers
• Meets or Exceeds Stringent Automotive Design
Requirements Including “Hardware Require-
ments for LIN, CAN and FlexRay Interfaces in
Automotive Applications”, Version 1.3, May 2012
• Six Filters and Two Masks, with Optional Filtering
on the First Two Data Bytes
• Supports SPI Modes 0,0and 1,1
• Specific SPI Commands to Reduce SPI Overhead
• High-Noise Immunity Due to Differential Bus
Implementation
• Buffer Full, and Request-to-Send Pins
Configurable as General Purpose I/O
• High ESD Protection on CANH and CANL, meets
IEC61000-4-2 up to ±8 kV
• One Interrupt Output Pin
Description:
The MCP25625 is a complete, cost-effective and
small-footprint CAN solution that can be easily added
to a microcontroller with an available SPI interface.
The
MCP25625
interfaces
directly
with
microcontrollers operating at 2.7V to 5.5V, there are no
external level shifters required. In addition, the
MCP25625 connects directly to the physical CAN bus,
supporting all requirements for CAN high-speed
transceivers.
The MCP25625 meets the automotive requirements for
high-speed (up to 1 Mb/s), low quiescent current,
electromagnetic compatibility (EMC) and electrostatic
discharge (ESD).
