RF Receivers Procurement Notes

Verify the specific suffix JTR against official STMicroelectronics documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the target application's voltage levels and interface requirements before procurement. Cross-reference the RoHS status and moisture sensitivity level (MSL) with manufacturing constraints. Confirm that the 169-ball BGA footprint matches the PCB design guidelines provided in the datasheet.

RF Receivers Selection Notes

Select this component when multi-constellation support and high sensitivity are required in a compact form factor. Consider the 169-ball BGA package size and thermal characteristics for PCB layout. Evaluate the available memory resources (256kB SRAM, 512kB ROM) against application software needs. Ensure the host processor supports the required digital interfaces such as SPI or UART for configuration and data output.

RF Receivers Part Context

This part belongs to the STA8090 family of GNSS receivers designed by STMicroelectronics. It shares architectural similarities with other variants like the STA8090FGTR but differs in package and specific interface configurations. The family targets applications requiring robust global navigation satellite system performance with low power consumption and small footprint.

RF Receivers Replacement Considerations

Official substitutes include the STA8090FGTR and STA8090F4GBTR. Verify pin-to-pin compatibility and software register mapping differences between these variants. Ensure that the alternative part number meets the same environmental and electrical specifications required by the original design.
