MCP2515T-E集成電路（IC）的控制器規(guī)格書PDF中文資料

MCP2515T-E屬于集成電路（IC）的控制器。由微芯科技股份有限公司制造生產(chǎn)的MCP2515T-E控制器該系列產(chǎn)品主要用于在采用不同通信協(xié)議和/或信令方法的端點之間提供信息連接。示例包括將 I2C 總線連接到 UART，將 USB 連接到 I2C、SPI、以太網(wǎng)或 UART、以太網(wǎng) MAC 和 PHY 等的器件。此外，還包括用于通過為點對點通信設(shè)計的接口建立多路連接的器件，例如 USB 集線器控制器。

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:
