MCP2515
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 A standby current (typical) (Sleep mode)
Temperature ranges supported:
- Industrial (I): -40°C to +85°C
- Extended (E): -40°C to +125°C
Description
Microchip Technology’s MCP2515 is a stand-alone
Controller
Area
Network
(CAN)
controller
that
implements the CAN specification, version 2.0B. It is
capable of transmitting and receiving both standard
and extended data and remote frames. The MCP2515
has two acceptance masks and six acceptance filters
that are used to filter out unwanted messages, thereby
reducing the host MCUs overhead. The MCP2515
interfaces with microcontrollers (MCUs) via an industry
standard Serial Peripheral Interface (SPI).
