Analog Devices Inc./Maxim Integrated DS1631EVSYS1#

Overview

DS1631EVSYS1# from Maxim Integrated is an evaluation system for the DS1631 high-precision digital thermometer and thermostat IC, featuring a fully assembled DS1631AU+ in 8-pin µMAX package, I²C interface via dual 6-pin Pmod™ connectors, and Windows-compatible GUI software for real-time temperature sampling, threshold configuration, and TOUT polarity control.

For engineers reviewing the DS1631EVSYS1# datasheet, DS1631EVSYS1# pinout, DS1631EVSYS1# application, or DS1631EVSYS1# equivalent, this EV system enables rapid validation of DS1631 functionality-including 9–12-bit resolution selection, continuous/one-shot conversion modes, TH/TL register programming, and hardware thermostat flag monitoring-without custom PCB design or firmware development.

Technical Context

The DS1631EVSYS1# integrates the DS1631AU+ IC with the USB2PMB2 adapter board to form a complete I²C master–slave evaluation platform. It supports user-supplied I²C masters via Pmod-compatible J1 (TSW-106-08-S-D-RA) or direct test-point access to SCL, SDA, A0–A2, TOUT, and GND.

Hardware includes on-board 0.1µF ceramic decoupling (C1), 4.7kΩ pull-up resistors (R1/R2), and test points for VDD (+2.7V to +5.5V), TOUT, and GND. The GUI provides register-level read/write access, conversion status feedback, EEPROM activity indication, and real-time temperature history plotting.

FAQ

What does the DS1631EVSYS1# evaluate?

The DS1631EVSYS1# evaluates the DS1631 high-precision digital thermometer and thermostat IC. It includes the DS1631AU+ in µMAX-8 package, USB2PMB2 adapter, and Windows GUI software. The system demonstrates full DS1631 functionality including temperature conversion, TH/TL threshold setting, TOUT polarity control, and I²C register access - all without requiring external firmware or hardware design.

Does the DS1631EVSYS1# require external power or drivers?

No, the DS1631EVSYS1# operates from USB power when used with the included USB2PMB2 adapter. It requires only the DS1631GUISetup.msi installer and Windows OS (XP through 10). No additional drivers, external VDD supplies, or custom code are needed to begin evaluating the DS1631EVSYS1# - the GUI handles I²C communication, register reads/writes, and real-time plotting automatically.

Can the DS1631EVSYS1# be used with non-Windows hosts?

The DS1631EVSYS1# GUI software (DS1631EVKit.exe) is officially supported only on Windows XP, 7, 8, 8.1, and 10. While the underlying I²C interface is standard, Maxim does not provide Linux or macOS drivers or GUI alternatives. Users requiring cross-platform access must implement custom I²C host software and interpret DS1631 register maps independently - the DS1631EVSYS1# itself remains hardware-compatible but software-limited to Windows.

How is the DS1631 IC interfaced on the DS1631EVSYS1# board?

The DS1631 IC (DS1631AU+) is soldered in 8-pin µMAX package and connected via dedicated traces to the J1 Pmod™ connector (TSW-106-08-S-D-RA), exposing SCL, SDA, A0–A2, TOUT, and GND. Test points allow direct probing of VDD, TOUT, and GND. Pull-up resistors (4.7kΩ) and decoupling capacitor (0.1µF) are onboard, ensuring compliant I²C operation for the DS1631EVSYS1#.

What temperature resolution and conversion modes does the DS1631EVSYS1# support?

The DS1631EVSYS1# supports all DS1631-native resolution settings (9-, 10-, 11-, and 12-bit) and conversion modes (continuous or one-shot) via its GUI Configuration groupbox. Conversion time adjusts automatically per resolution selection. These settings directly configure the DS1631AU+ on the board - no hardware modification is required to change resolution or mode during DS1631EVSYS1# evaluation.
