Based on the proven EPCOS piezoresistive MEMS technology the sensor module provides high accuracy and long-term stability. The very small size of only 2.78 mm × 2.23 mm and the low current consumption allows the integration into a multitude of mobile and stationary applications like personal navigation devices, mobile phones, altimeters and hard disk drives. Two high speed serial interfaces, I2C (3.4 MHz) and SPI (20 MHz), offer a high flexibility to connect the T5403 to almost every microcontroller platform. After initialisation calibration coefficients need to be transferred from the sensor memory to the microcontroller. Afterwards the sensor transmits the raw pressure and temperature readings on request. The user can select between four different operating modes from 5.1 Pa (0.42 m) to 2.7 Pa (0.22 m) RMS noise. The calculation of the actual pressure and altitude is done by the microcontroller.

It consists of a piezoresistive MEMS pressure sensor element and an ASIC with integrated temperature sensor, analog to digital converter ADC, memory and digital circuitry. The analog bridge voltage of the pressure sensor and the output voltage of the temperature sensor are routed through a multiplexer and a gain stage to the ADC. The logic-core controls the different function blocks. After initialisation the calibration parameters stored in the memory will be transmitted to the MCU (microcontroller unit). Afterwards only the raw pressure and temperature values are transmitted. After a request from the MCU a pressure or/and a temperature measurement is performed. Depending on the accuracy, time and power consumption requirements one out of four different operation modes can be selected before a measurement is executed. The end of a measurement is indicated on the EOC (end of conversion) pin. Then the MCU can request the raw measurement values and calculate the actual pressure and temperature values using the calibration data. To optimize power consumption the T5403 enters the idle mode between two measurements. Further details and source code examples are available in an application note.

Some parts of this publication contain statements about the suitability of our products for certain areas of application. These statements are based on our knowledge of typical requirements that are often placed on our products in the areas of application concerned. We nevertheless expressly point out that such statements cannot be regarded as binding statements about the suitability of our products for a particular customer application. As a rule, EPCOS is either unfamiliar with individual customer applications or less familiar with them than the customers themselves. For these reasons, it is always ultimately incumbent on the customer to check and decide whether an EPCOS product with the properties described in the product specification is suitable for use in a particular customer application. 2. We also point out that in individual cases, a malfunction of electronic components or failure before the end of their usual service life cannot be completely ruled out in the current state of the art, even if they are operated as specified. In customer applications requiring a very high level of operational safety and especially in customer applications in which the malfunction or failure of an electronic component could endanger human life or health (e.g. in accident prevention or life-saving systems), it must therefore be ensured by means of suitable design of the customer application or other action taken by the customer (e.g. installation of protective circuitry or redundancy) that no injury or damage is sustained by third parties in the event of malfunction or failure of an electronic component. 3. The warnings, cautions and product-specific notes must be observed. 4. In order to satisfy certain technical requirements, some of the products described in this publication may contain substances subject to restrictions in certain jurisdictions (e.g. because they are classed as hazardous). Useful information on this will be found in our Material Data Sheets on the Internet (www.epcos.com/material). Should you have any more detailed questions, please contact our sales offices. 5. We constantly strive to improve our products. Consequently, the products described in this publication may change from time to time. The same is true of the corresponding product specifications. Please check therefore to what extent product descriptions and specifications contained in this publication are still applicable before or when you place an order. We also reserve the right to discontinue production and delivery of products. Consequently, we cannot guarantee that all products named in this publication will always be available. The aforementioned does not apply in the case of individual agreements deviating from the foregoing for customer-specific products. 6. Unless otherwise agreed in individual contracts, all orders are subject to the current version of the “General Terms of Delivery for Products and Services in the Electrical Industry” published by the German Electrical and Electronics Industry Association (ZVEI). 7.
