MCP2515屬于開發(fā)板套件編程器的評(píng)估演示板及套件。由微芯科技股份有限公司制造生產(chǎn)的MCP2515評(píng)估和演示板及套件該系列產(chǎn)品提供了一種方便的方法，在經(jīng)過驗(yàn)證的實(shí)施環(huán)境中評(píng)估某些重點(diǎn)器件的性能或特性。評(píng)估方法通常有完善的文檔說明，并且視乎具體情況由評(píng)估軟件提供支持。產(chǎn)品通常由印刷電路板組成，板上已裝有重點(diǎn)器件以及必要或有用的支持元器件，另外也可能包括其他組件，例如電纜或電源。對(duì)于數(shù)量特別多或類別獨(dú)特的器件類別(如 ADC、DAC 和開關(guān)模式電源)，評(píng)估平臺(tái)可組合為一個(gè)單獨(dú)的產(chǎn)品系列。

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 MCU’s overhead. The MCP2515 interfaces with microcontrollers (MCUs) via an industry standard Serial Peripheral Interface (SPI).

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

degradation

? 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
