MCP25025-I/SL - 8-Channel CAN I/O Expander | Microchip
MPN: MCP25025-I/SL ✗ پایان تولیدMCP25025-I/SL نمای کلی
A CAN input/output expander extends the number of digital inputs, outputs, and mixed I/O available to a CAN-connected controller. This MCP25025 family member combines CAN reception and transmission resources with configurable digital I/O and one-wire support, allowing a host microcontroller or CAN node to monitor and control external signals without implementing every peripheral function on its main controller. In the broader hierarchy, it is a CAN interface and I/O expansion IC used within embedded control systems.
The verified product information identifies up to 8 digital I/O lines, up to 2 PWM outputs, 3 transmit buffers, 2 receive buffers, 1 mask, 2 filters, and a user-configurable one-wire line-driver option. The 4 MHz clock supports the device's digital interface functions, while the 2.7 V to 5.5 V supply range accommodates common embedded-system rails. Because the supplied data does not state the complete pin-level mapping or all timing and electrical limits, those details should be confirmed in the manufacturer datasheet before schematic release.
The MCP25025-I/SL is suitable for automotive, industrial, and embedded applications that use CAN-connected remote I/O. It can expand a controller's digital sensing and actuation capability, support PWM-driven loads or indicators, and provide a one-wire option where the system architecture requires it. The 14-SOIC package also follows a conventional surface-mount assembly format, simplifying integration with existing embedded boards.
Designers should confirm the exact SOIC footprint, pin functions, CAN transceiver interface arrangement, and external component requirements against the Microchip datasheet. The one-wire capability should be treated as an optional configuration rather than an assumption about the default pinout. Likewise, the supplied data confirms the 2.7 V to 5.5 V supply range, but it does not establish current consumption, CAN bit-rate limits, temperature limits, or automotive qualification status.
This page consolidates the verified distributor and manufacturer information for MCP25025-I/SL and distinguishes documented functions from parameters that still require datasheet confirmation. It is intended for engineers evaluating CAN I/O expansion, PWM output capability, and one-wire integration. Availability, pricing, and lifecycle conditions should be checked with the listed suppliers or through an authorized sourcing channel at the time of purchase.

کاربردهای معمول
MCP25025-I/SL مناسب است برای 6 کاربردs: Distributed Automotive CAN I/O, Industrial CAN Remote Control, Embedded Control Module, PWM-Controlled Auxiliary Loads, Remote Sensor and Switch Aggregation, Instrumentation and Test Equipment.
Distributed Automotive CAN I/O
The MCP25025-I/SL fits distributed vehicle electronics that use CAN to connect remote sensors, switches, actuators, and indicator controls. Its documented up-to-8 digital I/O channels allow a CAN node to add local input and output capacity without placing every signal on the central microcontroller. Up to 2 PWM outputs can support suitable lamp, motor, or proportional-control functions, while the configurable one-wire option provides additional line-driver flexibility. Before release, verify the exact automotive qualification, temperature range, CAN transceiver requirements, and fault behavior in the Microchip documentation.

Industrial CAN Remote Control
In industrial control cabinets and remote actuator nodes, the MCP25025-I/SL can expand CAN-connected digital I/O for limit switches, relay-control signals, status lamps, and simple sequencing functions. The verified 8-channel I/O capability is useful when the host controller has fewer direct pins than the external equipment requires. The device's 2.7 V to 5.5 V supply range supports common embedded supply rails, but industrial temperature protection, isolation, surge requirements, and safety functions are not established by the supplied data and must be verified separately.
پیشنهادی
Embedded Control Module
The MCP25025-I/SL can serve as a local I/O companion in a microcontroller-based controller where a host processor communicates through CAN and needs extra digital interface points. The 4 MHz clock and configurable I/O resources make the device suitable for deterministic embedded control architectures, provided the host firmware follows the documented register and timing model. Because the supplied data does not state interrupt behavior, electrical timing, or current consumption, system timing and power budgets should be completed from the full manufacturer datasheet.
پیشنهادی
PWM-Controlled Auxiliary Loads
The documented availability of up to 2 PWM outputs makes MCP25025-I/SL relevant to CAN-controlled auxiliary loads such as small motors, dimmable indicators, or proportional actuators. The I/O expander can receive commands over the CAN-connected control path and handle local output functions away from the main processor. The exact PWM frequency, resolution, output drive capability, and thermal limits are not included in the verified data, so the load and duty cycle must be checked against the datasheet before implementation.
پیشنهادی
Remote Sensor and Switch Aggregation
The MCP25025-I/SL can aggregate digital sensors, switches, and interlock inputs in a remote CAN node, reducing the number of wiring runs to a central controller. Its up-to-8 digital I/O channels provide a compact way to supervise multiple binary conditions and return their status through the CAN system. The one-wire option can be useful in designs that need a configurable line-driver resource, but its exact pin and protocol behavior must be verified. Signal conditioning, isolation, debounce requirements, and fault-safe wiring remain system-level concerns.
پیشنهادی
Instrumentation and Test Equipment
In programmable test and measurement equipment, the MCP25025-I/SL can provide CAN-addressed digital fixture control alongside a host controller. Up to 8 I/O channels can operate relays, limit inputs, status indicators, or fixture interlocks, while the configurable one-wire feature may support a local line-driver function. The 2.7 V to 5.5 V operating range is convenient for mixed embedded rails, but the verified results do not specify noise, timing, input thresholds, or isolation. Those details require validation for precision or safety-related test paths.

یادداشت‌های طراحی
Begin the layout with the exact MCP25025-I/SL pinout and recommended application circuit in the Microchip datasheet. Confirm the 14-SOIC footprint, pin-one orientation, exposed component spacing, and routing clearances before fabrication. Keep CAN and digital signal paths away from switching-power nodes and follow the datasheet's recommended grounding and decoupling arrangement; the supplied search snippets do not provide enough pin-level detail to substitute generic SOIC layout conventions.
Do not treat the family name MCP25025 as sufficient evidence that every suffix has identical behavior. The -I/SL ordering code must be matched to the package, temperature, and device configuration used in the schematic. Similarly, the configurable one-wire option should not be treated as permanently enabled. Verify register defaults, one-wire routing, PWM availability, and CAN interface behavior in the exact datasheet revision before writing firmware.
The verified supply range is 2.7 V to 5.5 V, but the supplied data does not include operating current, input thresholds, I/O drive strength, or CAN transceiver power requirements. Before power-budgeting, determine whether the system needs a separate CAN physical-layer transceiver and how much current is required by the host bus. Add the required protection, filtering, and decoupling components according to the manufacturer recommendations rather than estimating values from generic interface ICs.
