MCP2515-E/STVAO 概述
A CAN controller is an interface IC that manages CAN frame transmission and reception, while a CAN transceiver converts the controller’s logic signals into differential bus signals. The MCP2515 sits between a microcontroller and an external transceiver, making it useful when the system already has a suitable transceiver or requires modular bus-isolated hardware.
The MCP2515 family supports standard and extended data frames, remote frames, data-byte filtering, acceptance filtering, status and interrupt control, and time-triggered protocol support. The verified source describes it as pin and function compatible with the MCP2510 while providing upgraded features such as faster throughput, data-byte filtering, and time-triggered protocols. The MCP2515-E/STVAO is identified in the supplied data as a two-wire, stand-alone CAN controller.
Typical implementations place the MCP2515 beside a microcontroller and connect its SPI port to the host. CANH and CANL are not provided by this controller; those signals belong to the external CAN transceiver. PCB layout should separate digital SPI routing from the analog and bus-side transceiver area, provide a stable clock, and follow the external transceiver’s termination and grounding guidance.
The -E/STVAO ordering information and the comparison data identify the device as a TSSOP-20 industrial CAN controller. The supplied snippets do not provide a complete electrical characteristic table, absolute maximum ratings, pricing, or a complete verified pin map. Those fields are therefore marked for data needed rather than inferred from unverified assumptions.
This page consolidates the verified product identity, official datasheet, source links, application context, and design cautions. It does not claim that the controller includes a physical-layer transceiver, and it does not invent electrical values absent from the supplied evidence.

典型应用
MCP2515-E/STVAO 适用于 6 应用s: Microcontroller CAN Communication, Industrial Automation Bus, CAN Sensor and Actuator Network, Robotics and Equipment Control, Vehicle Network Interface Module, Diagnostic and Test Equipment.
Microcontroller CAN Communication
MCP2515-E/STVAO fits an embedded controller design that already uses SPI and needs to add CAN connectivity without integrating a bus transceiver into the same IC. The host MCU can configure the controller, transmit and receive standard or extended frames, and use filtering to reduce unnecessary interrupts. The verified 1 Mbit/s capability supports industrial and automotive-adjacent communication tasks, while the external transceiver remains responsible for CANH and CANL. The TSSOP-20 package helps keep the controller compact, but the PCB footprint and pin map must be confirmed from the exact ordering code.
推荐
Industrial Automation Bus
Use MCP2515-E/STVAO as the protocol controller in an industrial automation node when the system already separates logic-level CAN control from the physical transceiver. Its CAN 2.0B support, remote-frame capability, data-byte filtering, and 1 Mbit/s maximum rate are useful for machine control and status monitoring. The design should use a transceiver suitable for the industrial voltage range and environment, preserve the recommended termination scheme, and validate bit timing under the worst-case oscillator and propagation conditions. The supplied data does not confirm the controller’s full temperature or supply limits.
推荐
CAN Sensor and Actuator Network
The MCP2515-E/STVA0 can connect a microcontroller-based measurement or actuation module to a shared CAN network while preserving a modular controller/transceiver architecture. Standard and extended data-frame support allows the system to carry ordinary sensor values and longer identifiers where required, while remote frames support request-style communication. Because the IC does not include the physical transceiver, select one with appropriate bus-fault and common-mode characteristics. Firmware should configure acceptance masks and interrupts carefully to avoid unnecessary processing on multi-node networks.
推荐
Robotics and Equipment Control
For robotics, laboratory equipment, or mobile machinery, MCP2515-E/STVA0 provides a protocol engine between an embedded controller and a CAN transceiver. The 1 Mbit/s maximum rate is suitable for command, diagnostic, and sensor traffic when the complete network design supports that rate. The controller’s SPI interface allows compact integration with a microcontroller, while acceptance filtering and interrupt status help the host identify relevant frames. Use careful grounding and bus-layout practices because the MCP2515 is a digital controller and the external transceiver is the component exposed to bus transients and wiring hazards.
推荐
Vehicle Network Interface Module
MCP2515-E/STVA0 can be used in a vehicle or equipment CAN gateway when the system designer chooses a separate transceiver and verifies all automotive requirements. The device implements CAN 2.0B and supports standard, extended, and remote frames, making it suitable for a controller-based network interface. However, the supplied evidence does not establish AEC-Q100 qualification for this exact -E/STVAO ordering code. Automotive deployment therefore requires manufacturer qualification records, temperature verification, EMC review, transient testing, and confirmation that the selected transceiver meets the vehicle’s protection requirements.
推荐
Diagnostic and Test Equipment
MCP2515-E/STVA0 is appropriate for a test fixture or service interface that needs to exchange CAN frames with a host controller over SPI. The controller can support standard and extended identifiers, remote frames, acceptance filtering, and status reporting while the external transceiver connects the fixture to the bus under test. Designers should program bit timing from the actual oscillator and transceiver propagation delay, isolate the host from bus faults as required, and verify the complete pinout before fabrication. The verified source supports the 1 Mbit/s capability, but does not provide a complete timing table.

设计说明
Treat MCP2515-E/STVAO as a digital CAN controller, not as the bus transceiver. Place the controller close to the host MCU and route SPI, reset, interrupt, and control signals away from the external transceiver and CAN bus traces. Keep the transceiver-side return path and decoupling layout consistent with the selected transceiver datasheet. The supplied data confirms TSSOP-20 for the comparison variant but does not provide a complete pin map, so verify the land pattern and pin numbering against the exact order code before fabrication.
Do not assume that all MCP2515 ordering suffixes are interchangeable. MCP2515-E/STVAO, MCP2515-I/STVAO, MCP2515-I/SOVAO, MCP2515T-I/ST, and MCP2515-E/SO appear in separate search results with potentially different package, temperature, qualification, or feature details. Before substitution, compare the exact package drawing, pin names, supply limits, clock requirements, interrupt behavior, and CAN timing settings. Similar CAN-controller descriptions alone do not prove drop-in compatibility.
Design CAN timing from the complete clock and transceiver chain, not only from the nominal 1 Mbit/s controller rate. Account for oscillator tolerance, SPI clock timing, transceiver propagation delay, cable delay, and the controller’s bit-timing configuration. Use the manufacturer timing specifications and transceiver guidance for the final values. For a new board, provide clean ground references and avoid routing high-current or switching-node copper through the controller’s digital return path.
The supplied evidence does not provide the MCP2515-E/STVAO supply voltage, current dissipation, or thermal-resistance values, so a numerical power calculation cannot be made responsibly. Before production, estimate controller dissipation from the actual supply voltage and measured operating current, then compare the result with the manufacturer’s package and thermal limits. The external CAN transceiver may dissipate additional power during faults and should be included in the system thermal review.
合规信息
The supplied search results identify Microchip Technology and the MCP2515 family, but do not provide extracted RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations for this exact ordering code.
