DS28E18
Description
The DS28E18 is a simple communications bridge that resides at a remote SPI or I2C sensor and allows the sensor to be controlled by just two wires coming from the host system. It reduces the wire count from six (for SPI) or four (for I2C).
Key Features
- Operate Remote I2C or SPI Devices Using SingleContact 1-Wire Interface
- Extending I2C/SPI Communication Distance
- Reduce Six Wires (for SPI) or Four Wires (for I2C) to Two Wires
- 512-Byte Sequencer for Autonomous Operation of Attached Devices
- Two Configurable GPIO Pins for Additional Peripheral Control
- No External Power Required
- DS28E18 Parasitically Powered from 1-Wire
- I2C/SPI Peripheral Power Derived from the 1-Wire Line
- Flexible 1-Wire and I2C/SPI Master Operational Modes
- Supports Standard (11kbps) and Overdrive (90kbps) 1-Wire Communication
