Key Features

  • CAN V2.0B interface for robust industrial-grade communication at up to 1 Mbps without requiring a separate CAN controller
  • Integrated 10-bit ADC with 8-bit I/O expander enables combined digital and analog remote sensing over a single CAN bus
  • SOIC-14 package with RoHS-compliant e3 code for lead-free assembly in industrial and automotive applications

Applications

The MCP25055-I/SL is ideal for distributed I/O nodes in industrial automation, factory floor monitoring, and building control systems connected via CAN bus networks. Its combination of 8-bit I/O and 10-bit ADC in a single device reduces BOM complexity for remote sensor modules measuring analog signals such as 0 V to 5 V transducer outputs. Automotive body electronics and agricultural equipment applications also benefit from its CAN V2.0B compliance and compact SOIC-14 form factor.

Frequently Asked Questions

How many digital I/O channels and what ADC resolution does the MCP25055-I/SL provide for remote sensing nodes?

The MCP25055-I/SL provides 8 bidirectional digital I/O channels and a 10-bit ADC, giving 1024 quantization levels across the input voltage range. This combination allows a single CAN node to simultaneously monitor digital switch states and measure analog sensor outputs such as 0 V to 5 V pressure or temperature transducers without additional ICs.

What CAN bus speed does the MCP25055-I/SL support and how does that affect system latency in an industrial network?

The MCP25055-I/SL supports CAN V2.0B at data rates up to 1 Mbps, enabling I/O scan cycle times below 1 ms per node in typical industrial PLC networks. At 500 kbps, the standard industrial CAN speed, round-trip command and response latency is approximately 2 ms per node, sufficient for machine control and monitoring applications with 8 digital inputs.

How does the MCP25055-I/SL compare to SPI-based I/O expanders like MCP23S08 for CAN-connected designs?

Unlike the MCP23S08 which uses a 10 MHz SPI interface requiring a host MCU with a dedicated SPI port, the MCP25055-I/SL communicates directly over CAN bus at up to 1 Mbps, eliminating the need for a host controller. This allows up to 112 remote nodes on a single CAN network without consuming MCU SPI resources, at the cost of slightly lower raw throughput compared to SPI. The 10-bit ADC integration further differentiates the MCP25055-I/SL for analog sensor applications.
