MCP2515 Stand-Alone CAN Controller with SPI Interface Features Description Microchip Technologys MCP2515 is a stand-alone Implements CAN V2.0B at 1 Mb/s: Controller Area Network (CAN) controller that imple- - 0 to 8-byte length in the data field ments the CAN specification, Version 2.0B. It is capable - Standard and extended data and remote of transmitting and receiving both standard and frames extended data and remote frames. The MCP2515 has Receive Buffers, Masks and Filters: two acceptance masks and six acceptance filters that - Two receive buffers with prioritized message are used to filter out unwanted messages, thereby storage reducing the host MCUs overhead. The MCP2515 interfaces with microcontrollers (MCUs) via an industry - Six 29-bit filters standard Serial Peripheral Interface (SPI). - Two 29-bit masks Data Byte Filtering on the First Two Data Bytes Package Types (applies to standard data frames) 18-Lead PDIP/SOIC Three Transmit Buffers with Prioritization and TXCAN 1 18 V Abort Features DD RXCAN 2 17 RESET High-Speed SPI Interface (10 MHz): CLKOUT/SOF 3 - SPI modes 0,0 and 1,1 16 CS 4 One-Shot mode Ensures Message Transmission TX0RTS 15 SO is Attempted Only One Time TX1RTS 5 14 SI Clock Out Pin with Programmable Prescaler: TX2RTS 6 13 SCK - Can be used as a clock source for other OSC2 7 12 INT device(s) OSC1 8 11 RX0BF Start-of-Frame (SOF) Signal is Available for V 9 10 RX1BF SS Monitoring the SOF Signal: 20-Lead TSSOP - Can be used for time slot-based protocols 1 20 and/or bus diagnostics to detect early bus V TXCAN DD 2 19 degradation RXCAN RESET 3 18 CLKOUT/SOF CS Interrupt Output Pin with Selectable Enables 4 17 SO TX0RTS Buffer Full Output Pins Configurable as: 5 16 TX1RTS SI 6 15 NC NC - Interrupt output for each receive buffer 7 14 TX2RTS SCK - General purpose output 8 13 OSC2 INT Request-to-Send (RTS) Input Pins Individually 9 12 OSC1 RX0BF 10 11 Configurable as: V RX1BF SS - Control pins to request transmission for each 20-Lead QFN* transmit buffer - General purpose inputs Low-Power CMOS Technology: 20 19 18 17 16 15 SO CLKOUT 1 - Operates from 2.7V-5.5V 14 SI - 5 mA active current (typical) TX0RTS 2 EP 13 NC -1 A standby current (typical) (Sleep mode) TX1RTS 3 21 12 SCK Temperature Ranges Supported: 4 NC 11 INT - Industrial (I): -40C to +85C 5 TX2RTS 678 9 10 - Extended (E): -40C to +125C * Includes Exposed Thermal Pad (EP) see Table 1-1. 2003-2019 Microchip Technology Inc.
