DP2515 — Standalone CAN Controller with SPI Interface

The DP2515 is a fully standalone Controller Area Network (CAN) protocol controller that fully supports CAN 2.0B specification. It can transmit and receive standard/extended data frames and remote frames.

Two acceptance masks and six acceptance filters significantly reduce MCU overhead by filtering unwanted messages.

Communication with the host MCU is via industry-standard SPI.

Key Features

• Full CAN 2.0B support, up to 1 Mbps

• 0–8 byte data field, standard/extended/remote frames

• 2 receive buffers with prioritization

• 6 × 29-bit acceptance filters + 2 × 29-bit masks

• Filtering on first two data bytes (standard frames)

• 3 transmit buffers with prioritization and abort capability

• High-speed SPI (10 MHz), supports modes 0,0 and 1,1

• One-shot mode (single transmission attempt)

• Clock-out pin with programmable prescaler

• Start-of-Frame (SOF) output for monitoring and diagnostics

• Configurable interrupt and “buffer full” pins

• Individual RTS pins for immediate transmission or as GPI

• Low-power CMOS:

• 2.7–5.5 V supply

• 5 mA typical active current

• 1 µA typical standby (sleep mode)

• Temperature range: –40°C to +85°C

Packages

• SOP-18, TSSOP-20

Applications

• Intelligent nodes in CAN bus systems
