MCP2510-I/ST

Controllers Overview

The MCP2510-I/ST is a stand-alone CAN protocol controller implementing CAN V2.0A and V2.0B specifications. It supports standard and extended data frames with message lengths of 0 to 8 bytes, operating at programmable bit rates up to 1 Mb/s. The device features three transmit buffers and two receive buffers, six acceptance filters, and two acceptance masks to reduce microcontroller overhead. Communication with the host MCU is handled via an SPI interface supporting modes 0,0 and 1,1, with clock speeds up to 5 MHz at 4.5V. It operates on a supply voltage between 3.0V and 5.5V, drawing 5 mA typical active current and 10 µA standby current. The Industrial grade variant functions within a temperature range of -40°C to +85°C.

Controllers Feature Summary

• Implements Full CAN V2.0A and V2.0B protocols including support for remote frames and loop-back self-test mode.
• Integrates hardware message management with three prioritized transmit buffers and two receive buffers featuring abort capabilities.
• Provides flexible interrupt management through dedicated pins for each receive buffer and configurable request-to-send inputs.
• Utilizes low-power CMOS technology allowing operation from 3.0V to 5.5V with dedicated low power sleep mode.

Controllers Applications

• Industrial automation systems requiring robust fieldbus communication
• Automotive electronic control units and sensor networks
• Medical equipment and diagnostic interfaces

Controllers Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature rating of -40°C to +85°C. Confirm the '/ST' designation corresponds to the 20-lead TSSOP package type required for your PCB layout. Ensure the order quantity matches the manufacturer's packaging constraints if purchasing in tape and reel formats.

Controllers Selection Notes

Select this component when a standalone CAN controller is needed to offload protocol processing from the main MCU. It is suitable for designs requiring CAN 2.0B compliance with moderate data throughput needs. Consider the available GPIO pins for RTS and BF signals if hardware-based transmission initiation or reception alerts are preferred over software polling.

Controllers Part Context

The MCP2510 belongs to Microchip's family of standalone CAN controllers designed to simplify CAN bus integration. Unlike integrated transceivers, it handles only the protocol layer, requiring an external transceiver for physical bus connection. This separation allows flexibility in choosing transceivers based on isolation or drive requirements while maintaining standardized protocol handling.

Controllers Replacement Considerations

MCP2515T-I/ST: Offers identical protocol support but includes additional receive filters and masks for enhanced message filtering without MCU intervention.

Controllers FAQ

Does the MCP2510 include an integrated CAN transceiver?

No, the MCP2510 is a protocol controller only. An external CAN transceiver must be connected to the TXCAN and RXCAN pins to interface with the physical bus.

What SPI modes does the MCP2510 support?

The device supports SPI modes 0,0 and 1,1, allowing compatibility with a wide range of microcontrollers.

How many acceptance filters are available for message filtering?

The MCP2510 provides six full acceptance filters and two full acceptance filter masks to manage incoming messages efficiently.
