MCP2515T-I/SOVAO

Controllers Overview

The MCP2515T-I/SOVAO is a stand-alone CAN controller implementing the CAN V2.0B specification at data rates up to 1 Mb/s. It interfaces with microcontrollers via an industry-standard SPI protocol block supporting modes 0,0 and 1,1 at speeds up to 10 MHz. The device features three transmit buffers with prioritization and abort capabilities, alongside two receive buffers equipped with six 29-bit acceptance filters and two masks for message filtering. Operating on low-power CMOS technology, it functions within a supply voltage range of 2.7V to 5.5V, drawing typical active current of 5 mA and standby current of 1 μA in sleep mode. The component supports industrial temperature ranges from -40°C to +85°C.

Controllers Feature Summary

• Implements CAN V2.0B standard with support for standard and extended data frames as well as remote frames.
• Integrates hardware message filtering using six acceptance filters and two masks to reduce host MCU overhead.
• Provides one-shot transmission mode to ensure messages are attempted only once, suitable for deterministic protocols.
• Includes programmable clock output pins and start-of-frame monitoring signals for bus diagnostics.

Controllers Applications

• Automotive electronic systems requiring robust Controller Area Network communication.
• Industrial control networks utilizing distributed real-time data exchange.
• Embedded designs integrating CAN connectivity via SPI interface.

Controllers Procurement Notes

Verify the specific suffix 'SOVAO' against official Microchip documentation to confirm RoHS compliance and lead-free status. Confirm package type and pinout compatibility with existing PCB layouts. Ensure the ordering code matches the exact temperature grade and revision required for the target application environment.

Controllers Selection Notes

Select this component when a stand-alone CAN controller is required to offload protocol processing from the main microcontroller. It is suitable for applications needing flexible message filtering and multiple transmit buffers. Consider the SPI interface speed and available GPIO pins for interrupt and request-to-send connections during system design.

Controllers Part Context

This part belongs to the MCP2515 family of stand-alone CAN controllers manufactured by Microchip Technology. It serves as a bridge between SPI-based microcontrollers and CAN buses, handling complex protocol tasks such as bit timing, error management, and frame arbitration internally.

Controllers Replacement Considerations

Check for direct pin-compatible alternatives within the MCP2515 series or newer generations like the MCP2517/2518 if updated features are needed. Verify that any substitute maintains identical SPI command sets and register mappings to ensure software compatibility without modification.
