DEVICE OVERVIEW
1.1.1
The MCP2561/2FD is a high-speed CAN device,
fault-tolerant device that serves as the interface
between a CAN protocol controller and the physical
bus. The MCP2561/2FD device provides differential
transmit and receive capability for the CAN protocol
controller, and is fully compatible with the ISO-11898-2
and ISO-11898-5 standards.
The Loop Delay Symmetry is guaranteed to support
data rates that are up to 5 Mbps for CAN FD (Flexible
Data rate). The maximum propagation delay was
improved to support longer bus length.
Typically, each node in a CAN system must have a
device to convert the digital signals generated by a
CAN controller to signals suitable for transmission over
the bus cabling (differential output). It also provides a
buffer between the CAN controller and the high-voltage
spikes that can be generated on the CAN bus by
outside sources.
NORMAL MODE
Normal mode is selected by applying low-level voltage
to the STBY pin. The driver block is operational and
can drive the bus pins. The slopes of the output signals
on CANH and CANL are optimized to produce minimal
electromagnetic emissions (EME).
The high speed differential receiver is active.
1.1.2
STANDBY MODE
The device may be placed in Standby mode by
applying high-level voltage to the STBY pin. In Standby
mode, the transmitter and the high-speed part of the
receiver are switched off to minimize power
consumption. The low-power receiver and the wake-up
filter blocks are enabled to monitor the bus for activity.
The receive pin (RXD) will show a delayed
representation of the CAN bus, due to the wake-up
filter.
The MCP2561/2FD supports two modes of operation:
The CAN controller gets interrupted by a negative edge
on the RXD pin (Dominant state on the CAN bus). The
CAN controller must put the MCP2561/2FD back into
Normal mode, using the STBY pin, in order to enable
high speed data communication.
• Normal Mode
• Standby Mode
The CAN bus wake-up function requires both supply
voltages, VDD and VIO, to be in valid range.
1.1
Mode Control Block
These modes are summarized in Table 1-1.

Transmitter Function
The CAN bus has two states:
• Dominant State
• Recessive State
A Dominant state occurs when the differential voltage
between CANH and CANL is greater than VDIFF(D)(I).
A Recessive state occurs when the differential voltage
is less than VDIFF(R)(I). The Dominant and Recessive
states correspond to the Low and High state of the TXD
input pin, respectively. However, a Dominant state
initiated by another CAN node will override a
Recessive state on the CAN bus.
1.3
1.4
Internal Protection
CANH and CANL are protected against battery
short-circuits and electrical transients that can occur on
the CAN bus. This feature prevents destruction of the
transmitter output stage during such a fault condition.
The device is further protected from excessive current
loading by thermal shutdown circuitry that disables the
output drivers when the junction temperature exceeds
a nominal limit of +175°C. All other parts of the chip
remain operational, and the chip temperature is
lowered due to the decreased power dissipation in the
transmitter outputs. This protection is essential to
protect against bus line short-circuit-induced damage.
Receiver Function
In Normal mode, the RXD output pin reflects the
differential bus voltage between CANH and CANL. The
Low and High states of the RXD output pin correspond
to the Dominant and Recessive states of the CAN bus,
respectively.

Permanent Dominant Detection
1.6
The MCP2561/2FD device prevents two conditions:
• Permanent Dominant condition on TXD
• Permanent Dominant condition on the bus
In Normal mode, if the MCP2561/2FD detects an
extended Low state on the TXD input, it will disable the
CANH and CANL output drivers in order to prevent the
corruption of data on the CAN bus. The drivers will
remain disabled until TXD goes High.
In Standby mode, if the MCP2561/2FD detects an
extended Dominant condition on the bus, it will set the
RXD pin to Recessive state. This allows the attached
controller to go to Low-Power mode until the Dominant
issue is corrected. RXD is latched High until a
Recessive state is detected on the bus, and the
wake-up function is enabled again.
Both conditions have a time-out of 1.25 ms (typical).
This implies a maximum bit time of 69.44 µs
(14.4 kHz), allowing up to 18 consecutive dominant bits
on the bus.
1.7
Power-On Reset (POR) and
Undervoltage Detection
The MCP2561/2FD has undervoltage detection on
both supply pins: VDD and VIO. Typical undervoltage
thresholds are 1.2V for VIO and 4V for VDD.
When the device is powered on, CANH and CANL
remain in a high-impedance state until both VDD and
VIO exceed their undervoltage levels. Once powered
on, CANH and CANL will enter a high-impedance state
if the voltage level at VDD drops below the undervoltage
level, providing voltage brown-out protection during
normal operation.
In Normal mode, the receiver output is forced to
Recessive state during an undervoltage condition on
VDD. In Standby mode, the low-power receiver is only
enabled when both VDD and VIO supply voltages rise
above their respective undervoltage thresholds. Once
these threshold voltages are reached, the low-power
receiver is no longer controlled by the POR comparator
and remains operational down to about 2.5V on the
VDD supply (MCP2561/2FD). The MCP2562FD
transfers data to the RXD pin down to 1.8V on the VIO
supply.

1.7.1
TRANSMITTER DATA
INPUT PIN (TXD)
The CAN transceiver drives the differential output pins
CANH and CANL according to TXD. It is usually
connected to the transmitter data output of the CAN
controller device. When TXD is Low, CANH and CANL
are in the Dominant state. When TXD is High, CANH
and CANL are in the Recessive state, provided that
another CAN node is not driving the CAN bus with a
Dominant state. TXD is connected to an internal pull-up
resistor (nominal 33 k) to VDD or VIO, in the
MCP2561FD or MCP2562FD, respectively.
1.7.2
GROUND SUPPLY PIN (VSS)
Ground supply pin.
1.7.3
SUPPLY VOLTAGE PIN (VDD)
Positive supply voltage pin. Supplies transmitter and
receiver, including the wake-up receiver.
1.7.4
RECEIVER DATA
OUTPUT PIN (RXD)
RXD is a CMOS-compatible output that drives High or
Low depending on the differential signals on the CANH
and CANL pins, and is usually connected to the
receiver data input of the CAN controller device. RXD is
High when the CAN bus is Recessive, and Low in the
Dominant state. RXD is supplied by VDD or VIO, in the
MCP2561FD or MCP2562FD, respectively.
1.7.5
SPLIT PIN (MCP2561FD ONLY)
Reference Voltage Output (defined as VDD/2). The pin
is only active in Normal mode. In Standby mode, or
when VDD is off, SPLIT floats.
2014 Microchip Technology Inc.
1.7.6
VIO PIN (MCP2562FD ONLY)
Supply for digital I/O pins. In the MCP2561FD, the
supply for the digital I/O (TXD, RXD and STBY) is
internally connected to VDD.
1.7.7
CAN LOW PIN (CANL)
The CANL output drives the Low side of the CAN
differential bus. This pin is also tied internally to the
receive input comparator. CANL disconnects from the
bus when MCP2561/2FD is not powered.
1.7.8
CAN HIGH PIN (CANH)
The CANH output drives the high-side of the CAN
differential bus. This pin is also tied internally to the
receive input comparator. CANH disconnects from the
bus when MCP2561/2FD is not powered.
1.7.9
STANDBY MODE INPUT PIN (STBY)
This pin selects between Normal or Standby mode. In
Standby mode, the transmitter, high speed receiver and
SPLIT are turned off, only the low power receiver and
wake-up filter are active. STBY is connected to an
internal MOS pull-up resistor to VDD or VIO, in the
MCP2561FD or MCP2562FD, respectively. The value
of the MOS pull-up resistor depends on the supply voltage. Typical values are 660 k for 5V, 1.1 M for 3.3V
and 4.4 M for 1.8V
1.7.10
EXPOSED THERMAL PAD (EP)
It is recommended that this pad is connected to VSS for
the enhancement of electromagnetic immunity and
thermal resistance.

The bit time of a recessive bit after five dominant bits is measured on the RXD pin. Due
to asymmetry of the loop delay, and the CAN transceiver not being a push pull driver,
the recessive bits tend to shorten.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.
