7 / 42 page  Detailed Description The DS1921G Thermochron iButton is an ideal device to monitor the temperature of any object it is attached to or shipped with, such as perishable goods or con- tainers of temperature-sensitive chemicals. The read/write NV memory can store an electronic copy of shipping information, date of manufacture and other important data written as clear as well as encrypted files. Note that the initial sealing level of the DS1921G achieves IP56. Aging and use conditions can degrade the integrity of the seal over time, therefore, for applica- tions with significant exposure to liquids, sprays, or other similar environments, it is recommended to place the Thermochron in the DS9107 iButton capsule. The DS9107 provides a watertight enclosure that has been rated to IP68 (refer to Application Note 4126: Understanding the IP (Ingress Protection) Ratings of iButton Data Loggers and Capsule). Overview Figure 1 shows the relationships between the major control and memory sections of the DS1921G. The device has seven main data components: 64-bit lasered ROM; 256-bit scratchpad; 4096-bit general- purpose SRAM; 256-bit register page of timekeeping, control, and counter registers; 96 bytes of alarm time- stamp and duration logging memory; 126 bytes of Thermochron iButton _______________________________________________________________________________________ 7 GENERAL-PURPOSE SRAM ALARM TIMESTAMP AND DURATION LOGGING MEMORY REGISTER PAGE MEMORY FUNCTION CONTROL 64-BIT LASERED ROM 256-BIT SCRATCHPAD CONTROL LOGIC 32.768kHz OSCILLATOR 3V LITHIUM IO TEMPERATURE CORE DATA-LOG MEMORY INTERNAL TIMEKEEPING, CONTROL REGISTERS, AND COUNTERS HISTOGRAM MEMORY ROM FUNCTION CONTROL 1-Wire PORT PARASITE-POWERED CIRCUITRY DS1921G Figure 1.
