DS1616开发板套件编程器的评估演示板及套件规格书PDF中文资料

DESCRIPTION

The DS1616 is an integrated temperature/data recorder. It combines a Real Time Clock (RTC), temperature sensor, and a three input mux’ed 8-bit Analog-to-Digital Converter (ADC). Datalogging is supported for all four data channels and the and histogram functionality is supported for the temperature sensor and ADC Channel 1 only. A programmable sample rate feature makes the device ideal for applications requiring datalogging over short or long time frames.

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 userprogrammable 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
