MCP2510 MCP2510 MCP2510 Stand-Alone CAN Controller with SPI Interface Features Description Implements Full CAN V2.0A and V2.0B at 1 Mb/s: The Microchip Technology Inc. MCP2510 is a Full Con- troller Area Network (CAN) protocol controller imple- - 0 - 8 byte message length menting CAN specification V2.0 A/B. It supports CAN - Standard and extended data frames 1.2, CAN 2.0A, CAN 2.0B Passive, and CAN 2.0B - Programmable bit rate up to 1 Mb/s Active versions of the protocol, and is capable of trans- - Support for remote frames mitting and receiving standard and extended mes- - Two receive buffers with prioritized message sages. It is also capable of both acceptance filtering storage and message management. It includes three transmit buffers and two receive buffers that reduce the amount - Six full acceptance filters of microcontroller (MCU) management required. The - Two full acceptance filter masks MCU communication is implemented via an industry - Three transmit buffers with prioritization and standard Serial Peripheral Interface (SPI) with data abort features rates up to 5 Mb/s. - Loop-back mode for self test operation Hardware Features: Package Types - High Speed SPI Interface 18 LEAD PDIP/SOIC (5 MHz at 4.5V I temp) 1 VDD TXCAN 18 - Supports SPI modes 0,0 and 1,1 - Clock out pin with programmable prescaler RXCAN 2 17 RESET - Interrupt output pin with selectable enables CLKOUT 3 16 CS - Buffer full output pins configureable as inter- TX0RTS 4 15 SO rupt pins for each receive buffer or as general TX1RTS 14 SI 5 purpose digital outputs 13 SCK TX2RTS 6 - Request to Send input pins configureable as control pins to request immediate message 12 INT OSC2 7 transmission for each transmit buffer or as 11 RX0BF OSC1 8 general purpose digital inputs 10 RX1BF VSS 9 - Low Power Sleep mode Low power CMOS technology: 20 LEAD TSSOP - Operates from 3.0V to 5.5V - 5 mA active current typical 1 20 VDD TXCAN 2 19 - 10 A standby current typical at 5.5V RXCAN RESET 3 18 CLKOUT CS 18-pin PDIP/SOIC and 20-pin TSSOP packages 4 17 TX0RTS SO Temperature ranges supported: 5 16 SI TX1RTS - Industrial (I): -40C to +85C 6 15 NC NC - Extended (E): -40C to +125C 7 14 SCK TX2RTS 8 13 INT OSC2 9 12 RX0BF OSC1 VSS 10 11 RX1BF 2007 Microchip Technology Inc.
