- SPI interface up to 5 MHz for easy connection to any microcontroller without built-in CAN peripheral
- 3 transmit and 2 receive message buffers with programmable acceptance filters and masks reducing host CPU interrupt load
- Low-power 3 V operation minimum at 16 MHz SPI clock, suitable for battery-powered CAN nodes

Applications
The MCP2510-I/ST is widely used to add CAN bus connectivity to microcontrollers and FPGAs that lack a native CAN peripheral, such as older PIC or AVR devices in automotive body-control modules and industrial fieldbus nodes. Its standalone operation with SPI interface makes it ideal for motor controllers, sensor gateways, and building-automation panels connecting to CANopen or DeviceNet networks. It is also used in diagnostic tools and embedded gateways where a compact, low-cost CAN interface is needed alongside an existing MCU.

Frequently Asked Questions
What CAN bus data rate does the MCP2510-I/ST support, and is it compatible with higher-speed CAN FD networks?
The MCP2510-I/ST supports CAN 2.0B at data rates up to 1 Mbps using NRZ encoding, which covers the full speed range of classical CAN. It does not support CAN FD (Flexible Data Rate) frames above 1 Mbps or extended payloads beyond 8 bytes, so it is suited for legacy CAN 2.0A/B networks but must be replaced with an MCP2517FD or similar device for CAN FD applications.
How does the MCP2510-I/ST connect to a host microcontroller, and what SPI clock speed is supported?
The MCP2510-I/ST uses a standard 4-wire SPI interface (SCK, SDI, SDO, CS) operating at up to 5 MHz, which is supported by virtually every modern MCU and FPGA. The SPI protocol uses a simple command set—read, write, bit-modify, and status—that is easy to implement in firmware, and the INT output pin signals the host immediately when a message is received or transmitted without polling.
How many CAN message buffers does the MCP2510-I/ST provide, and how does filtering work?
The device has 3 transmit buffers (TXB0–TXB2, each holding one full CAN frame with an 8-byte payload) and 2 receive buffers (RXB0–RXB1) backed by 6 acceptance filters and 2 masks. This hardware filtering checks the 11-bit or 29-bit CAN ID against the programmed masks and filters before passing a message to a receive buffer, which reduces the number of interrupts the host CPU must handle—important in high-traffic networks running at 500 kbps or 1 Mbps.
What supply voltage range does MCP2510-I/ST require, and can it operate at 3.3 V in a low-power application?
The MCP2510-I/ST operates from 2.7 V to 5.5 V, with guaranteed operation at 3 V minimum when the SPI clock is up to 16 MHz. At 3.3 V supply it interfaces directly with 3.3 V MCUs and transceivers without level shifters; at 5 V supply it drives 5 V CAN transceivers such as the MCP2551 directly. Typical active current is under 10 mA at 5 V, suitable for battery-assisted CAN sensor nodes.
When would a designer choose MCP2510-I/ST over an MCU with a built-in CAN peripheral for a new automotive node?
MCP2510-I/ST is preferred when the target MCU—such as a legacy PIC16 or AVR—has no on-chip CAN controller and swapping to a new MCU would require a large firmware rewrite. It is also chosen when the CAN node must be isolated (opto-coupled) from the MCU, since a standalone controller simplifies the isolation boundary to just the 4 SPI lines and INT. At unit costs below a dollar in volume, it adds CAN capability to an existing platform for under 1 USD additional BOM cost.
