Microchip | MCP2515-E/ST

The MCP2515-E/ST is a Stand-Alone CAN Controller with SPI Interface for implementing CAN specification V2.0B with bit rate up to 1 Mb/s. Available in surface mount TSSOP-20 package.

Features:

• Implements CAN V2.0B at 1 Mb/s:
• 0 – 8 byte length in the data field
• Standard and extended data and remote frames
• Receive buffers, masks and filters:
• Two receive buffers with prioritized message storage
• Six 29-bit filters
• Two 29-bit masks
• Data byte filtering on the first two data bytes (applies to standard data frames)
• Three transmit buffers with prioritization and abort features
• High-speed SPI Interface (10 MHz):
• SPI modes 0,0 and 1,1
• One-shot mode ensures message transmission is attempted only one time
• Clock out pin with programmable prescaler:
• Can be used as a clock source for other device(s)
• Start-of-Frame (SOF) signal is available for monitoring the SOF signal:
• Can be used for time-slot-based protocols and/or bus diagnostics to detect early bus degredation
• Interrupt output pin with selectable enables
• Buffer Full output pins configurable as:
• Interrupt output for each receive buffer
• General purpose output
• Request-to-Send (RTS) input pins individually configurable as:
• Control pins to request transmission for each transmit buffer
• General purpose inputs
• Low-power CMOS technology:
• Operates from 2.7V – 5.5V
• 5 mA active current (typical)
• 1 μA standby current (typical) (Sleep mode)
• Temperature ranges supported:
• Industrial (I): -40°C to +85°C
• Extended (E): -40°C to +125°C
