MCP2502X/5X

CAN I/O Expander Family

Features

Description

• Implements CAN V2.0B

The MCP2502X/5X devices operate as I/O expanders

for

a Controller Area Network (CAN) system,

- Programmable bit rate up to 1 Mb/s

- One programmable mask

- Two programmable filters

- Three auto-transmit buffers

- Two message reception buffers

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

microcontroller.

The devices are identical, with the following

exceptions:

- Does not require synchronization or

configuration messages

• Hardware Features

One Wire

- Non-volatile memory for user configuration

Device

CANbus

- User configuration automatically loaded on

MCP25055

Yes

- Eight general-purpose I/O lines individually

selectable as inputs or outputs

Yes

- Individually selectable transmit-on-pin-

change for each input

Yes

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.

- Four 10-bit, analog input channels with

programmable conversion clock and VREF

sources (MCP2505X devices only)

- Message scheduling capability

- Two 10-bit PWM outputs with independently

programmable frequencies

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.

- Device configuration can be modified via

CAN bus messages

- In-Circuit Serial Programming™ (ICSP™) of

default configuration memory

- Optional 1-wire CAN bus operation

• Low-power CMOS technology

- Operates from 2.7V to 5.5V

The device is pre-programmed in non-volatile memory

so that the part defaults to a specific configuration at

power-up.

- 10 mA active current, typical

- 30 µA standby current (CAN Sleep mode)

• 14-pin PDIP (300 mil) and SOIC (150 mil)

packages

• Available temperature ranges:

- Industrial (I): -40°C to +85°C

- Extended (E): -40°C to +125°C
