PRELIMINARY

DS1616

Temperature and Three Input

MUX’ed 8-bit Data Recorder

FEATURES

Measures four channels of data:

− Integrated 8-bit temperature sensor,

− Integrated 8-bit Analog-to-Digital Converter

(ADC) with a three input mux for measuring

up to three external sensors

Digital thermometer measures temperature

-40°C to +85°C in 0.5°C increments (-40°F to

+183.2°F in 0.9°F increments)

Digital thermometer provides ±2°C accuracy

Real Time Clock/Calendar in BCD format counts

seconds, minutes, hours, date, month, day of the

week, and year with leap year compensation. The

Real Time Clock is fully Y2K-compliant

Automatically wakes up and measures

temperature and/or ADC data at user-

programmable intervals from 1 to 255 minutes

2048-byte datalog memory

Records long-term temperature histogram in

63 bins with 2.0°C resolution

Records long-term ADC data histogram in 64 bins

with 4-bit resolution/bin (32 mV/bin) for ADC

Channel One

Programmable temperature-high and -low alarm

trip points

Programmable ADC data-high and -low alarm trip

points

Records time stamp and duration when

temperature or ADC Channel 1 Data leaves the

interval specified by the trip points

Two serial interface options: synchronous and

asynchronous

- 3-wire synchronous serial interface

- Asynchronous serial interface compatible with

standard UARTs

Memory partitioned into 32 byte pages for

packetizing data

On-chip 16-bit CRC generator to safeguard data

read operations in asynchronous communications

mode

Unique, factory lasered 64-bit serial number
