DS1922L, DS1922T

Temperature Logger iButton

With 8kB Datalog Memory

www.maxim-ic.com

GENERAL DESCRIPTION

SPECIAL FEATURES

The DS1922L/T temperature logger iButtons^®are

rugged, self-sufficient systems that measure

temperature and record the result in a protected

memory section. The recording is done at a user-

defined rate. A total of 8192 8-bit readings or 4096

16-bit readings taken at equidistant intervals ranging

from 1s to 273hrs can be stored. In addition to this,

there are 512 bytes of SRAM for storing application-

specific information and 64 bytes for calibration data.

A mission to collect data can be programmed to

begin immediately, or after a user-defined delay or

after a temperature alarm. Access to the memory and

control functions can be password protected. The

DS1922L/T is configured and communicates with a

host computing device through the serial 1-Wire^®

protocol, which requires only a single data lead and a

ground return. Every DS1922L/T is factory-lasered

with a guaranteed unique 64-bit registration number

that allows for absolute traceability. The durable

stainless-steel package is highly resistant to

environmental hazards such as dirt, moisture, and

shock. Accessories permit the DS1922L/T to be

mounted on almost any object, including containers,

pallets, and bags.

Automatically Wakes up, Measures Tempera-

ture, and Stores Values in 8kB of Datalog

Memory in 8- or 16-Bit Format
