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 that can filter out unwanted messages , thus reducing the main microcontroller (MCU) overhead. MCP2515 with MCU is connected via an industry-standard Serial Peripheral Interface (Serial Peripheral Interface, SPI) to achieve.

features of CAN-BUS to SPI :
 
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:
          – Two receive buffers with prioritized message storage          – Six 29 acceptance filters          – Two 29 -bitmasks
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 the 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 transmits buffer control pin is used to send messages immediately request          – General-purpose digital input pin
Low-power CMOS technology :
          – Operating voltage range of 4.75V to 5.25V          – 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
