DS1922L-F5# (MAXIM INTEGRATED PRODUCTS)

The DS1922L-F5# from Maxim Integrated Products is an iButton® temperature logger with 8KB datalog memory in F5 Can package. This rugged, self-sufficient system measures temperature and record the result in a protected memory section. The recording is done at a user-defined rate. A total of 8192 8bit readings or 4096 16bit readings, taken at equidistant intervals ranging from 1s to 273hr, can be stored. Additionally, 512bytes of SRAM store application specific information and 64bytes store calibration data. A mission to collect data can be programmed to begin immediately, after a user-defined delay or after a temperature alarm. Access to memory and control functions can be password protected. The DS1922L is configured and communicate with a host-computing device through serial 1-Wire® protocol which requires only a single data lead and a ground return. Each DS1922L is factory lasered with a unique 64bit registration number that allows for absolute traceability.
