DS2430AP/T&R Datasheet/PDFThe DS2430AP/T&R is a non-volatile memory device designed for use in limited space and thermal application areas. Powered by an ultra-low power supply with 2.7V toVCC, the device is ideal for remote sensing and data storage applications. The product includes a universal serial bus (USB) interface, an external interface, and a temperature and pressure sensing system. In addition, the device can be used on single-ended or differential bus interfaces.
The DS2430AP/T&R is a suite of digital components, including an 8-bit microcontroller, a 24-bit digital resistor, a 24-bit resistance-temperature converter (RTD), and a 12-bit temperature-to-digital converter (TDC). These components are designed for extreme accuracy over wide temperature ranges in industrial, automotive and consumer applications. The converter is designed to provide optimum performance in terms of accuracy, temperature stability, input resolution, and temperature range.
The 24-bit digital resistor allows for measurements of temperature and pressure with a resolution of 1.25 mV/K and 0.01 kPa/K. The DS2430AP/T&R features an eight-bit microcontroller, making it capable of controlling the device for varying types of applications including storing data in non volatile memory and various temperature overlays. Its external interfaces allow for control of various components using conventional I2C and SPI communications.
For temperature sensing, the DS2430AP/T&R uses a single external temperature sensor to measure temperatures up to 2000°C. The device includes a 12-bit temperature-to-digital converter (TDC) to convert the temperature sensor output into digital data that can be used by the microcontroller. The digital data is compared against predefined temperatures in the memory to determine the temperature inside the device. The TDC is also used to calculate an internal temperature-measurement scale that can be used for temperature-based settings of other components.
The DS2430AP/T&R is designed with a non-volatile memory that can store up to 16 bytes of data. This memory capability allows for data to be stored for a longer period of time and can be used for monitoring applications. This feature also provides for a quick recall of the stored data.
The device also contains a high-resolution pressure sensor that can be used to detect changes in pressure. The pressure sensor can detect temperature differences up to 0.01 kPa/K and is capable of providing a resolution of up to 0.5 pa/K.
The DS2430AP/T&R is specifically designed to be used in demanding environments, such as those found in automotive and industrial applications. Its robust design and high performance allow it to be used in extreme climates and in areas with limited access. Its excellent temperature performance makes it ideal for applications that require accurate temperature measurements.
