MCP2515-I/ST集成电路（IC）的控制器规格书PDF中文资料

MCP2515-I/ST属于集成电路（IC）的控制器。由美国微芯科技公司制造生产的MCP2515-I/ST控制器该系列产品主要用于在采用不同通信协议和/或信令方法的端点之间提供信息连接。示例包括将 I2C 总线连接到 UART，将 USB 连接到 I2C、SPI、以太网或 UART、以太网 MAC 和 PHY 等的器件。此外，还包括用于通过为点对点通信设计的接口建立多路连接的器件，例如 USB 集线器控制器。

描述 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
