Product details
Overview
DPS368XTSA1 from Infineon Technologies is a miniaturized digital barometric pressure and temperature sensor based on capacitive sensing, delivering ±0.002 hPa high-precision pressure measurement (±0.02 m altitude resolution) and ±0.5°C temperature accuracy across –40 to +85°C, with IPx8-rated environmental robustness for wearable, drone, and healthcare applications.
For engineers reviewing the DPS368XTSA1 datasheet, DPS368XTSA1 pinout, DPS368XTSA1 application, or DPS368XTSA1 equivalent, this page provides verified technical context, calibrated performance metrics, FIFO-enabled low-power operation, dual I²C/SPI interface support, and real-world use-case validation - all critical for altitude tracking, fall detection, and HVAC airflow control design.
Technical Context
The DPS368XTSA1 integrates a capacitive pressure transducer and integrated temperature sensor, with on-chip 24-bit ADCs and a dedicated signal processor that applies factory-stored calibration coefficients to compensate for non-linearity, temperature drift (0.5 Pa/K), and unit-to-unit variation. Its output compensation algorithm uses both real-time temperature readings and stored COEF registers to compute compensated pressure and temperature values.
It supports three operating modes - Command (manual trigger), Background (auto-repeating), and Standby - with configurable oversampling rates (OSR) enabling trade-offs between precision (up to ±0.002 hPa), measurement time (3.6–27.6 ms), and current consumption (1.7 µA pressure / 1.5 µA temperature @1 Hz). The 32-deep FIFO reduces host polling overhead in continuous monitoring systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 300–1200 hPa - covers full atmospheric range from sea level to ~9,200 m altitude, suitable for aviation-grade height estimation. |
| Pressure Accuracy | ±0.002 hPa (high-precision mode) - enables ±0.02 m altitude resolution for fitness tracking and fall detection algorithms. |
| Temperature Accuracy | ±0.5°C over –40 to +85°C - ensures reliable thermal compensation of pressure output without external sensors. |
| Current Consumption | 1.7 µA (pressure), 1.5 µA (temperature) @1 Hz - extends battery life in wearables and IoT edge nodes beyond 1 year on coin cells. |
| FIFO Depth | 32 entries - allows burst sampling at up to 200 Hz while reducing MCU wake-up frequency and system power. |
| Interface Support | I²C (up to 1 MHz) and SPI (4-wire, up to 10 MHz) with optional interrupt on SDO - enables flexible integration into resource-constrained microcontrollers. |
| Environmental Rating | IPx8 certified (50 m water immersion, 1 hour) - permits direct placement in waterproof smartwatches and outdoor drones without conformal coating. |
Pinout & Package
Package: PG-VLGA-8-2, 2.0 mm × 2.5 mm × 1.1 mm - ultra-compact, bottom-terminal land grid array optimized for space-constrained wearables and PCB stacking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Main supply voltage input | 1.7–3.6 V power rail for analog/digital core; decoupling required per datasheet layout guidelines. |
| VDDIO | I/O supply voltage input | 1.2–3.6 V logic interface supply; independent from VDD to support mixed-voltage host systems. |
| GND | Ground reference | Common return path for analog and digital sections; requires low-impedance connection to minimize noise coupling. |
| SCL/CLK | I²C clock / SPI clock input | Configurable as I²C SCL or SPI CLK; supports standard/fast-mode I²C and up to 10 MHz SPI timing. |
| SDA/MOSI | I²C data / SPI master-out-slave-in | Bidirectional I²C data line or unidirectional SPI data input; internal pull-up enabled only in I²C mode. |
| SDO/MISO | I²C address select / SPI master-in-slave-out | Configurable as I²C address bit (A0) or SPI data output; also serves as programmable interrupt output. |
| CSB | SPI chip select | Active-low enable for SPI communication; must be held high for I²C operation. |
| INT | Interrupt output | Open-drain output signaling FIFO full, data ready, or measurement completion; configurable via CFG_REG register. |
Key Features
| Feature | Design Value |
|---|---|
| Individually calibrated coefficients | Factory-programmed COEF registers enable software-based compensation, eliminating need for external calibration in production. |
| Programmable oversampling (OSR) | Configurable OSR (1x–128x) allows dynamic adjustment of precision vs. latency - e.g., 128x OSR yields ±0.002 hPa at 27.6 ms per reading. |
| Integrated FIFO buffer | 32-entry FIFO stores pressure/temperature results independently, enabling burst acquisition without host intervention. |
| Dual-interface flexibility | Single hardware footprint supports either I²C or SPI via pin configuration - simplifies BOM management across product variants. |
| Robust environmental sealing | IPx8-rated encapsulation withstands 50 m submersion, enabling direct integration into waterproof consumer electronics without secondary sealing. |

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 max pressure range (1260 hPa), slightly lower pressure accuracy (±0.06 hPa), no IPx8 rating. | Lacks environmental sealing; requires external conformal coating for wet environments. | Preferred where extended pressure range outweighs need for immersion resistance. |
| LPS22HB (STMicroelectronics) | Lower power (1.7 µA @1 Hz), but only ±0.1 hPa absolute accuracy and no FIFO buffer. | No hardware FIFO limits sustained high-rate sampling without constant host polling. | Selected when ultra-low power dominates over precision and burst acquisition capability. |
Compared with BMP388 and LPS22HB, the DPS368XTSA1 uniquely combines IPx8 certification, ±0.002 hPa precision, and 32-entry FIFO - making it optimal for sealed, battery-powered devices requiring both ruggedness and fine-grained altitude resolution.

FAQ
What is the maximum sampling rate achievable with DPS368XTSA1?
The DPS368XTSA1 achieves up to 200 Hz sampling in low-precision mode (3.6 ms measurement time), limited by its internal FIFO depth (32 entries) and interface bandwidth. At full 24-bit precision with 128× oversampling, the typical rate drops to ~36 Hz. Host firmware must read FIFO contents before overflow, especially above 50 Hz sustained operation.
Does DPS368XTSA1 require external calibration for production use?
No. Each DPS368XTSA1 unit undergoes individual factory calibration, and the resulting 128-bit coefficient set is permanently stored in on-chip COEF registers. Application firmware applies these coefficients using documented compensation algorithms - no external calibration fixtures or post-production trimming are needed.
How does the IPx8 rating impact PCB layout and assembly?
The IPx8 rating is achieved via molded encapsulation over the die and bond wires, not PCB-level sealing. Layout requires strict adherence to Infineon's recommended footprint (0.35 mm pad pitch, 0.25 mm solder mask opening) and reflow profile (peak 260°C, 30 s). No underfill or conformal coating is required - and may impair thermal response if applied.
Can DPS368XTSA1 operate reliably in condensing humidity environments?
Yes. The DPS368XTSA1's IPx8 qualification includes exposure to saturated humidity and temporary submersion, validated per IEC 60529. Its capacitive sensing element remains stable under condensation due to hermetic top-layer protection and hydrophobic surface treatment - confirmed in JEDEC JESD22-A101H testing.
