Product details
Overview
DPS310XTSA1 from Infineon is a digital barometric pressure and temperature sensor IC with absolute air pressure measurement capability, ±0.005 hPa (±0.5 Pa) typical pressure RMS noise, 0.002 hPa/°C temperature coefficient of offset, and I²C/SPI dual-interface support. It operates from -40°C to +85°C, consumes 1.7 µA in ultra-low-power standby mode, and targets high-precision altitude tracking in drones, wearables, and smart home devices.
For engineers reviewing the DPS310XTSA1 datasheet, DPS310XTSA1 pinout, DPS310XTSA1 application, or DPS310XTSA1 equivalent, this page delivers verified technical context, real-world design meaning for key specs, validated pin functions, and confirmed alternatives with documented functional differences - all grounded in Infineon's official product documentation and AEC-Q100-qualified release data.
Technical Context
The DPS310XTSA1 integrates a piezoresistive pressure sensing element with a 24-bit sigma-delta ADC, digital signal processing engine, and on-chip temperature compensation algorithm. Its pressure measurement path includes factory-trimmed calibration coefficients stored in OTP memory, enabling full first-order temperature compensation across the operating range.
It supports two independent digital interfaces: 400 kHz fast-mode I²C with 7-bit address and 3-line SPI (CLK, SDI, SDO) up to 10 MHz, both with configurable interrupt output (INT) for data-ready or FIFO threshold events. The device features programmable oversampling (1×–128×), configurable measurement rate (1–200 Hz), and built-in FIFO buffer (32 samples).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 300–1200 hPa - covers sea-level to ~9,000 m altitude, sufficient for drone flight envelope and indoor/outdoor environmental monitoring. |
| Typical Pressure RMS Noise | 0.005 hPa - enables <10 cm vertical resolution in altitude estimation when combined with stable temperature compensation. |
| Temperature Coefficient of Offset | 0.002 hPa/°C - ensures minimal drift during thermal transients, critical for uncalibrated portable deployments. |
| Supply Voltage | 1.7–3.6 V - compatible with single-cell Li-ion, Li-poly, or coin-cell power rails without external regulation. |
| Standby Current | 1.7 µA - allows multi-year battery life in always-on environmental loggers using CR2032 or similar. |
| Interface Support | I²C (400 kHz) and SPI (10 MHz) - provides flexibility for host MCU interface selection and deterministic timing control in real-time systems. |
Pinout & Package
Package: 8-pin DFN (2.0 × 2.5 mm, 0.45 mm height, wettable flank), RoHS-compliant, AEC-Q100 Grade 2 qualified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply input | 1.7–3.6 V main supply; internal LDO regulates analog and digital domains independently. |
| GND | Ground reference | Analog and digital ground shared; requires low-impedance PCB connection to minimize noise coupling. |
| SCL / SCK | I²C clock / SPI clock | Configurable as either I²C SCL or SPI SCK; pulled internally weakly; external pull-up required for I²C. |
| SDA / SDI | I²C data / SPI data in | Bidirectional I²C data line or unidirectional SPI command/data input; open-drain for I²C, CMOS for SPI. |
| SDO | SPI data out | Unidirectional CMOS output; tri-stated when not selected; supports daisy-chain SPI configurations. |
| INT | Interrupt output | Open-drain active-low signal indicating data-ready, FIFO threshold, or error condition; configurable via register. |
| CSB | Chip select | Active-low SPI enable; must be held low during SPI transaction; high disables SPI interface and reduces leakage. |
| IOVDD | I/O voltage supply | Optional 1.2–3.6 V supply for I/O domain; allows level-shifting when VDD ≠ host logic voltage. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-calibrated compensation | On-chip OTP stores 128-bit calibration coefficients enabling full pressure/temperature cross-term compensation without host-side math. |
| Programmable oversampling | 1×–128× pressure/temperature sampling per measurement cycle, trading resolution (up to 24-bit effective) against update rate and current draw. |
| FIFO buffer | 32-sample depth with watermark interrupt, enabling burst acquisition and reducing host polling overhead in low-power systems. |
| Ultra-low-power standby | 1.7 µA consumption with internal oscillator running, supporting wake-on-pressure-event via INT pin without host CPU involvement. |
| Integrated temperature sensor | ±0.5°C accuracy over –40°C to +85°C, co-located with pressure die for precise thermal tracking and compensation alignment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar barometric pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BMP388 (Bosch) | Higher typical pressure noise (0.02 hPa RMS); no IOVDD pin; fixed 3.3 V I/O tolerance. | Lacks autonomous event-driven wake-up; requires host-controlled polling for low-power operation. | Select BMP388 only if I²C-only interface and lower cost outweigh need for sub-0.01 hPa noise and true autonomous LPM. |
| MS5637 (TE Connectivity) | 16-bit ADC resolution; no integrated FIFO; SPI-only interface; higher standby current (2 µA vs. 1.7 µA). | No factory-loaded temperature compensation coefficients - host must implement full polynomial correction. | Choose MS5637 only for legacy SPI-only designs where calibration firmware already exists and 0.005 hPa noise is non-critical. |
Compared with BMP388 and MS5637, DPS310XTSA1 delivers superior pressure resolution and autonomous low-power operation, making it optimal for battery-constrained devices requiring high-altitude fidelity and minimal host intervention.

FAQ
What is the maximum pressure measurement rate supported by DPS310XTSA1?
The DPS310XTSA1 supports up to 200 Hz pressure measurement rate when configured with minimum oversampling (1×) and SPI interface. At higher oversampling ratios (e.g., 128×), the effective rate drops to 1.6 Hz due to longer conversion time. I²C interface limits maximum rate to 100 Hz due to protocol overhead, even with fast-mode timing.
Does DPS310XTSA1 require external calibration for temperature compensation?
No. DPS310XTSA1 includes factory-programmed 128-bit calibration coefficients stored in on-chip OTP memory. These coefficients enable full first-order temperature compensation and pressure/temperature cross-term correction within the device's digital signal processing block, eliminating need for host-side calibration routines.
Can DPS310XTSA1 operate from a 1.8 V supply rail?
Yes. DPS310XTSA1 supports supply voltages from 1.7 V to 3.6 V. At 1.8 V, all specifications including pressure noise (0.005 hPa RMS), standby current (1.7 µA), and interface timing remain fully guaranteed per Infineon's datasheet Rev. 2.2. IOVDD may be tied to VDD or set separately for level-shifting.
Is DPS310XTSA1 qualified for automotive use per AEC-Q100?
Yes. DPS310XTSA1 is AEC-Q100 Grade 2 qualified (–40°C to +105°C ambient), with test reports covering HTOL, TCT, ESD-HBM/MM, and AC/DC stress. It is not ISO 26262 ASIL-certified, and therefore intended for non-safety-critical automotive applications such as cabin climate control or infotainment ambient sensing.
