STA2058EXTR

Specialized Overview

The STA2058EXTR is a high-sensitivity GPS baseband processor from the TESEO platform, manufactured by STMicroelectronics. It integrates an ARM7TDMI 32-bit RISC CPU operating at up to 66 MHz with a dedicated High Performance GPS Engine (HPGPS). The device features 256 KB plus 16 KB of embedded Flash memory and 64 KB of RAM. It supports SBAS (WAAS/EGNOS) and includes an External Memory Interface for up to 64 Mbit of external storage. Key electrical parameters include a 3.0 V to 3.6 V I/O supply range and a 1.8 V core supply. Acquisition sensitivity reaches -146 dBm, with tracking sensitivity at -159 dBm.

Specialized Feature Summary

• Integrates a high-performance GPS engine with a 16-channel correlator and Emerald DSP for signal processing.
• Includes extensive communication interfaces such as four UARTs, two SPIs, two I2Cs, two CAN 2.0 modules, and USB 1.1.
• Features an external memory interface supporting glueless connection to SRAM, Flash, or ROM banks.
• Supports multiple low-power modes including WAIT, STOP, and STANDBY with wake-up capabilities.

Specialized Applications

• Portable Navigation Devices (PND)
• In-vehicle navigation systems
• Telematics units
• Consumer handheld devices

Specialized Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or certified partners. Confirm the specific ordering suffix matches the required package type and tape-and-reel configuration. Check for ECOPACK environmental compliance status if applicable. Ensure the source provides valid traceability documentation for quality assurance purposes.

Specialized Selection Notes

Select the STA2058EXTR when an integrated baseband solution with significant embedded memory is required. The LFBGA144 package variant specifically enables the External Memory Interface, which is absent in the LQFP64 version. Consider this component for designs needing robust serial connectivity options like dual CAN buses and USB support alongside GPS functionality.

Specialized Part Context

This component belongs to the TESEO GPS platform family, designed to work in conjunction with the STA5620 RF Front-End. It serves as the central processing unit for GPS signal acquisition and navigation data output within the broader ecosystem of ST's positioning solutions.
