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
exceptions:
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.
