Introduction:

The TWS581 is a new generation of high resolution pressure sensor from Tide Win Technology, Inc. It have UART Bus interface. The sensor module includes a high linearity pressure sensor and a low power 18 bits ΔΣADC with internal factory calibrated coefficients. It provides a precise digital 15 (up to 18) bits pressure and different operation modes that allow the user to optimize for conversion speed and current consumption. Small dimension of only 10.0 mm X 10.0mm and height of only 9.5mm allow for integration devices.

 

Features:

l   Gauge type pressure measurement

l   Span: Normal 5.8PSI or 0~300 mmHg (up to 360 mmHg)

l   Integrated Temperature Sensor for temperature compensation

l   Span and offset calibrated, simplify host MCU program loading

l   UART interface with data ready pin for simplified host MCU communication

l   Power for Circuit (VDD):　2.8 ~3.6V

l   Operating temperature range:　5~45℃

l   Large program memory for customization in different application

l   Up to nine IO PINs for custom applications

l   Implement system function without host MCU

 

Applications:

l   Pressure SystemSpecifications:

l   Industry/Medical System
