Description
The MCP2502X/5X devices operate as I/O expanders
for a Controller Area Network (CAN) system,
supporting CAN v2.0B active, with bus rates up to
1 Mb/s. The MCP2502X/5X allows a simple CAN node
to be implemented without the need for a
microcontroller.
The devices are identical, with the following

The MCP2502X/5X devices feature a number of
peripherals, including digital I/Os, four-channel 10-bit
A/D (MCP2505X), and PWM outputs with automatic
message transmission on change-of-input state. This
includes an analog input exceeding a preset threshold.
One mask and two acceptance filters are provided to
give maximum flexibility during system design with
respect to identifiers that the device will respond to.
The device can also be configured to automatically
transmit a unique message whenever any of several
error conditions occur.
The device is pre-programmed in non-volatile memory
so that the part defaults to a specific configuration at
Power-up.

MCP2502X/5X
Definition of Terms
The following terms are used throughout this
document:
I/O Expander – refers to the integrated circuit (IC)
device being described (MCP2502X/5X).
Input Message – term given to messages that are
received by the MCP2502X/5X and cause the internal
registers to be modified. Once the register modification
has been performed, the MCP2502X/5X transmits a
Command Acknowledge message to indicate that the
command was received and processed.
Command Acknowledge Message – term given to
the message that is automatically transmitted by the
MCP2502X/5X after receiving and processing an input
message.
Information Request Message – term given to the
Remote Request messages that are received by the
MCP2502X/5X that subsequently generate an output
message (data frame) in response.
Output Message – term given to the message that the
MCP2502X/5X sends in response to an Information
Request message.
On Bus Message – term given to the message that the
MCP2502X/5X transmits after completing the Power-On
and/or Self-Configuration sequences at timed intervals,
if enabled.
Self-Configuration – term used to describe the
process of transferring the contents of the EPROM
memory array to the SRAM memory array.
On Bus – term used to describe the condition when the
MCP2502X/5X is fully-configured and ready to transmit
or receive on the bus. This is the only state in which the
MCP2502X/5X can transmit on the bus.
Edge Detection – refers to the MCP2502X/5X’s ability
to automatically transmit a message based on the
occurrence of a predefined edge on any digital input.
Threshold Detection – refers to the MCP2502X/5X’s
ability to automatically transmit a message when a
predefined analog threshold is reached.
