MCP2515-I/STVAO

Controllers Overview

The MCP2515-I/STVAO is a stand-alone CAN controller implementing the CAN V2.0B specification with data rates up to 1 Mb/s. It interfaces with microcontrollers via a high-speed SPI interface operating at 10 MHz, supporting modes 0,0 and 1,1. The device features three transmit buffers with prioritization and abort capabilities, alongside two receive buffers with prioritized message storage. Message filtering is handled by six 29-bit acceptance filters and two 29-bit masks. Operating within an industrial temperature range of -40°C to +85°C, it utilizes low-power CMOS technology with a supply voltage range of 2.7V to 5.5V.

Controllers Procurement Notes

Verify the specific suffix 'VAO' against official Microchip documentation to confirm its exact meaning regarding package or tape-and-reel specifications. Ensure the component matches the required industrial temperature grade (-40°C to +85°C) and voltage range (2.7V-5.5V). Cross-reference the datasheet revision DS20001801J for accurate pinout and electrical characteristics before finalizing procurement orders.

Controllers Selection Notes

Select this component when a stand-alone CAN controller is needed to offload protocol processing from the main MCU. It is suitable for applications requiring robust message filtering to reduce host overhead. Consider the TSSOP-20 package for space-constrained designs. Ensure the system design includes an external CAN transceiver, as the MCP2515 handles only the digital protocol layer.

Controllers Part Context

The MCP2515 series serves as a versatile stand-alone CAN controller for various embedded applications. The '-I' designation indicates the Industrial temperature grade (-40°C to +85°C), while '/ST' specifies the 20-pin TSSOP package. This variant integrates the core CAN protocol engine with SPI connectivity, allowing flexible integration into diverse microcontroller-based architectures without dedicated CAN peripherals.
