SMbus to RS485 RS485 to I2C RS485 to SMbus I2C Hosts

Description: SMbus to RS485 RS485 to I2C RS485 to SMbus I2C Hosts 1. [Product Name]SMbus to RS485 RS485 to I2C RS485 to SMbus I2C to RS485 PMbus I2C (HOST) module debugging tool Second, [product introduction] 1. Working voltage: 3.0V ~ 5.5V. 2. This module has standard RS485 serial communication. 3. Maximum baud rate: The serial port supports 691.2K. 4. Buffer string length: I2C can send up to 255 words / time. 5. Received data length: 65535. 6. I2C can expand up to 256 I2C channels. 7. The maximum output and sink current is 25mA. 8. Product size: length * width * height = 45MM * 16MM * 10MM Third, [product characteristics] 1. Use the serial port to control all the functions of the 14-pin TSSOP packaged CMOS dedicated protocol conversion chip device (with features such as low power consumption, internal reset, internal crystal oscillator, etc.), eliminating the need to call the DLL, and directly using serial port debugging software can achieve I2C. All features. 2. With the output of multiple I2C expansion modules, it supports up to 4 * 8 * 8 = 256 independent I2C channels, DS18B20 temperature reading (128 channels), I2C channel expansion (256 channels), DHT11 / AM23XX humidity, temperature reading ( 4). 3. The module provides a standard serial port to I2C interface, which can realize the I2C read and write speed of 30KHz ~ 1MHz (with the extension of the slew rate control interface in the anti-interference high-speed mode). 4. I2C can send a maximum of 255 string lengths at one time, and additionally provide 4 programmable (GPIO1, GPIO2, GPIO3, GPIO4) IO input (with internal pull-up resistor), IO output (up to 25mA output and sink current) ).10-bit continuous ADC data acquisition (internal reference voltage, 1.024V, 2.048V, 4.096V, and VDD are provided, and the maximum number of continuous acquisitions per time: 65535), DAC output (internal reference voltage, 1.024V, 2.048V, 4.096V And VDD);5. The baud rate can be set by yourself, supporting bit rates 2400, 4800, 9600, 14400, 19200, 28800, 38400, 57600, 115200, 128000, 153600, 230400, 250000, 256000, 345600, 691200. 6, the bus for transparent transmission. When the design needs to expand the serial port of the microprocessor or hope to perform data exchange with the RS485 device on a separate I2C bus, using this chip can easily implement a solution. Fourth, [product applicable] 1. Color and light intensity sensor of TSC3404 series read. 2. For automated testing, such as module testing with I2C communication. 3. Support custom address: This chip supports RS-485 and custom address (254 addresses, and supports 00 broadcast address). 4. Directly used for general IO development, that is, adding a few I2C expansion chips, you can achieve any general IO input and output (such as: PCF8574), AD acquisition DA output (such as: PCF8591). 5, fully compatible with previous products, and support all SMBus protocols! 6. The module pin distance pin adopts the standard design (2.54mm), which can be directly welded to the universal board. Packing: IPC Warranty period: 120 days
