Key Specifications
| Complete manufacturer part number | FXPS7550A4ST1 |
|---|---|
| Manufacturer | STMicroelectronics |
| Description | Pressure sensors |
| Package / case | HQFN16 |
| Product category | Analog absolute pressure sensors |
| Pins | 16 |
| Operating temperature (manufacturer exact-order table) | -40 °C to 130 °C |
| Package terminal convention (manufacturer pin table) | 16 peripheral package contacts plus a separately numbered exposed die-attach pad17, which must connect to VSS. HQFN16 counts the peripheral contacts; pad17 is not a seventeenth independent signal pin. |
| Package drawing provenance | Original NXP SOT1573-1 mechanical drawing. The target ST datasheet explicitly rebrands the NXP document and retains its outline under license; this is a package drawing, not a product or current-lot photograph. |
| Measurement pressure range (manufacturer exact-order table) | 20 kPa to 550 kPa |
| Output interface (manufacturer exact-order table and pin section) | Analog ratiometric output |
| Package body dimensions (nominal; manufacturer package section) | 4 x 4 x 1.98 mm |
| Lead pitch (manufacturer mechanical section) | 0.8 mm |

| Lead time | To be confirmed |
Technical documentation and image source
Complete ordering code and original description are independently parsed from the manufacturer catalog card; documented corrections retain the original wording and primary proof. Temperature uses the linked manufacturer datasheet or the explicitly named exact-order reference with its junction/ambient and range/maximum scope shown in the published field label; source limitations and applicable conditions are retained in evidence. Absolute-maximum ratings do not guarantee all electrical performance across the interval. This does not verify every electrical table. Pin count and exact literal manufacturer package reference are independently crosschecked; the image is not a current-lot photograph or guaranteed marking. No certification is inferred from a suffix.
DigiKey package reference image for HQFN16. Confirm electrical pin functions in the datasheet. Actual lot appearance and top marking require current-lot confirmation.
