Introduction
CEPARK MCP2515 CAN controller module using MCP2515, while using high-speed CAN transceiver TJA1050 . Onboard independent keys ,
Microchip 's MCP2515 is a stand-alone controller area network (Controller Area Network, CAN) protocol controller , fully supports CAN V2.0B specifications. The device can send and receive standard and extended data and remote frames . MCP2515 comes with two acceptance masks and six acceptance filters can filter out unwanted messages , thus reducing the main microcontroller (MCU) overhead. MCP2515 with MCU is connected via an industry standard Serial Peripheral Interface (Searial Peripheral Interface, SPI) to achieve.

MCP2515 features
Fully supports CAN V2.0B technical specifications, the communication speed is 1Mb / s:
- Length of the data field 0-8 bytes
- Standard and extended data frames and remote frames
Receive Buffer , acceptance and acceptance filter mask register register:
- Two receive buffers with prioritized message storage
- Six 29 acceptance filters
- Two 29 -bit masks
head and two data bytes filtering ( for standard data frames )
Three transmit buffers with prioritization and abort function
High-speed SPI interface (10 MHz):
- Support the SPI mode 0,0 and 1,1
One-shot mode ensures that packets are sent to try only once
with programmable prescaler clock output pin :
- Can be used as a clock source for other devices
You can start frame signal (Start-of-Frame, SOF), for monitoring the SOF signal:
- Can be used in slot protocol and / or bus diagnostics to detect early
Line performance degradation
Enable interrupt settings with selectable output pin
" buffer full " output pin can be configured as :
- Each receive buffer interrupt pin
- General purpose digital output pin
" Request to Send (Request-to-Send, RTS)" each input pin can be configured as :
- Each transmit buffer control pin is used to send messages immediately request
- General purpose digital input pin
Low-power CMOS technology :
- Operating voltage range of 2.7V to 5.5V
- 5mA typical operating current
- 1A typical standby current ( sleep mode )
Operating temperature range :
- Industrial (I): -40 C to +85 C
- Extended (E): -40 C to +125 C
