The DS2405 Addressable Switch is an open drain N-channel transistor that can be turned on or off by matching the 64-bit factory-lasered registration number within each part. The 64-bit number consists of an 8-bit family code, a unique 48-bit serial number, and an 8-bit cyclic redundancy check. Communication with the DS2405 follows the standard Dallas Semiconductor 1-Wire protocol and can be accomplished with a single port pin of a microcontroller. Multiple DS2405 devices can reside on a common 1-Wire bus creating a MicroLAN. The network controller circuitry is embedded within the chip including a search algorithm to determine the identity of each DS2405 on the network. The open drain output (PIO pin) for each DS2405 on the MicroLan can be independently toggled on or off whether there is one or many devices sharing the same 1-Wire bus. The logic level of the PIO pin for each device on the MicroLan can also be individually sensed and reported to the bus master.
Open-drain PIO pin is controlled by matching 64-bit, laser-engraved registration number associated with each device
Logic level of open drain output can be determined over 1-Wire® bus for closed-loop control
PIO pin sink capability is greater than 4mA at 0.4V
Multiple DS2405s can be identified on a common 1-Wire bus and be turned on or off independent of other devices on the bus
Unique, factory-lasered and tested 64-bit registration number (8-bit family code +48-bit serial number +8-bit CRC tester) assures absolute identity because no two parts are alike
Built-in multidrop controller ensures compatibility with other MicroLAN products
Reduces control, address, data, and power to a single data pin
Directly connects to a single port pin of a microprocessor and communicates at up to 16.3kbits/s
8-bit family code specifies DS2405 communications requirements to reader
Belle Isle 2020 05/29/2020 - 05/31/2020, Detroit, MI 2020 Detroit Grand Prix - Chevrolet Detroit Grand Prix presented by Lear Fast Facts The Chevrolet Detroit Grand Prix presented by Lear was hosted on Belle Isle, May 29 - 30 2020. The event featured the cars of the NTT IndyCar Series, the IMSA WeatherTech SportsCar Championship and the Trans Am Series presented by Pirelli. The weekend is collectively referred to as the Chevrolet Detroit Grand Prix presented by Lear and it once again featured the Chevrolet Dual in Detroit IndyCar doubleheader.
