NXP Semiconductors PCT2075DP-ARD Arduino Shield
NXP PCT2075DP-ARD Arduino Shield is built around the PCT2075DP IC and works as a daughter card that can be connected through an Arduino port to various Arduino compatible (including original Arduino Uno R3) boards. The board is intended to test and measure the characteristics of the PCT2075DP 1°C accuracy digital temperature sensor and thermal watchdog produced by NXP Semiconductors.
Additionally, the daughterboard has software support and a graphical user interface (Windows platform) for the following NXP evaluation boards: MIMXRT1050-EVK board, LPC55S69-EVK development board, and 8MMINILPD4-EVK board.
The host device communicates with the sensor through a bidirectional Fm+ I2C-bus. Among the device under test (DUT) IC, the board is equipped with an Arduino port and the necessary components for easy testing, shortening the time to make measurements and check the operation of the PCT2075DP IC. A special feature of the evaluation board is the presence of a heating resistor that is placed on the top of the DUT IC. The heating resistor is controlled with an NMOS transistor which acts as an ON/OFF circuit, allowing the user to slightly modify the temperature of the sensor. The GUI software can control the heating element and monitor the temperature measured by the sensor.
Features
- Pin-for-pin replacement for LM75 series but allows up to 27 devices on the bus
- 11-bit ADC that offers a temperature resolution of 0.125°C
- Temperature accuracy of
- ±1°C (max.) from -25°C to +100°C
- ±2°C (max.) from -55°C to +125°C
- Programmable temperature threshold and hysteresis set points during operation
- Connector for external access to I2C-bus
- Onboard heating resistor with ON/OFF control circuit
- Onboard LED for overtemperature signaling
- Equipped with Arduino Uno R3 port for direct connection with Arduino devices
- Fully compliant with MIMXRT1050-EVK board, including GUI (Windows 10)
- Fully compliant with LPC55S69-EVK board, including GUI (Windows 10)
