Product details
Overview
STA2058 from STMicroelectronics is a high-sensitivity GPS baseband IC featuring an embedded 66 MHz ARM7TDMI processor, 256 KB + 16 KB Flash, 64 KB RAM, and a dedicated High Performance GPS Engine (HPGPS) supporting SBAS (WAAS/EGNOS). It delivers -146 dBm acquisition sensitivity and 2 m autonomous positioning accuracy, and is used in portable navigation devices (PNDs), telematics systems, and handheld GPS receivers.
For engineers reviewing the STA2058 datasheet, STA2058 pinout, STA2058 application, or STA2058 equivalent, key selection considerations include its dual-package support (LQFP64/LFBGA144), external memory interface capability, integrated RTC with backup supply, CAN 2.0B dual-channel support, and low-power standby modes down to 3 µA.
Technical Context
The STA2058 integrates a hardened HPGPS IP core with 16 correlators and Emerald DSP, enabling real-time acquisition and tracking using internal 1023×32-bit RAM banks. Its ARM7TDMI CPU executes GPS firmware directly from embedded Flash or external memory via glueless EMI supporting up to 64 Mbit SRAM/Flash/ROM.
Power management includes three voltage domains (V33 I/O, V18 core, V18BKP backup), programmable low-power modes (WFI, LPWFI, STOP, STANDBY), and independent 32 kHz RTC oscillator with dedicated supply-enabling continuous timekeeping during deep sleep without core power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM7TDMI 32-bit RISC running at up to 66 MHz; executes GPS navigation algorithms and host application logic. |
| Embedded Memory | 256 KB + 16 KB Flash (100K erase/program cycles) + 64 KB RAM; stores full GPS stack including acquisition, tracking, navigation, and output formatting. |
| GPS Sensitivity | -146 dBm acquisition, -159 dBm tracking; enables reliable signal lock under weak-signal conditions (e.g., urban canyons, indoors with assisted GNSS). |
| Time-to-First-Fix | 1 s reacquisition, 2.5 s hot start, 34 s warm start, 39 s cold start; optimized for rapid location recovery after brief outages or power cycling. |
| Position Accuracy | 2 m CEP50 autonomous (no differential correction); sufficient for consumer-grade PNDs and asset tracking without SBAS augmentation. |
| ADC | 4-channel 12-bit sigma-delta ADC with 0–2.5 V input range and 1 kHz sample rate; supports analog sensor inputs (e.g., battery voltage, temperature, motion detection). |
| Operating Temp | -40 °C to +85 °C; qualified for automotive cabin and industrial outdoor deployment without derating. |
Pinout & Package
LFBGA144 (10 × 10 × 1.7 mm) and LQFP64 (10 × 10 × 1.4 mm) packages are supported. The LFBGA144 variant includes full EMI support and additional GPIOs; LQFP64 omits EMI and reduces I/O count to 30 usable pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V18 | Core supply input | 1.8 V supply for ARM7TDMI core; must be decoupled with ≥10 µF tantalum + 33 nF ceramic if using internal regulator. |
| V33 | I/O supply input | 3.3 V digital supply for all I/O peripherals (UART, SPI, I²C, CAN, USB); internally tied to V33IO-PLL. |

| P0.15 / WAKEUP | Dedicated wake-up input | Schmitt-triggered GPIO with 0.7 V low / 1.8 V high thresholds; triggers exit from STOP/STANDBY on level/edge event. |
| nRSTINn | Reset input | Asynchronous active-low reset with 100 ns filtered pulse rejection; ensures robust immunity to board-level noise. |
| GPSDAT[0:1] | GPS data interface | Dual-pin serial interface to STA5620 RF front-end; carries raw GPS baseband samples and control signals. |
Key Features
| Feature | Design Value |
|---|---|

| USB 1.1 device controller | Full-speed (12 Mbps) USB interface with configurable endpoints and suspend/resume; supports firmware updates and NMEA data streaming over standard USB CDC ACM. |
| HDLC controller | Hardware-accelerated HDLC unit supporting NRZ/NRZI/FM0/Manchester encoding; offloads protocol framing for satellite or cellular modem interfacing. |
| Programmable low-power modes | Five distinct power states (RUN, WFI, LPWFI, STOP, STANDBY) with current draw from 150 mA down to 3 µA; enables multi-day battery life in portable GPS loggers. |
| Integrated RTC with backup domain | Real-time clock powered independently by V18BKP/VSSBKP; maintains time across full system power cycles and retains calendar/date during STANDBY_0 mode. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar GPS baseband applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| u-blox UBX-M8030 | Integrated GNSS (GPS/Galileo/GLONASS/BeiDou) vs. GPS-only; no embedded ARM core-requires external host MCU. | Supports multi-constellation use cases but lacks on-chip navigation stack execution; relies on host for NMEA parsing and sensor fusion. | Select when multi-GNSS coverage and minimal BOM count outweigh need for self-contained firmware execution. |
| Qualcomm QCC3071 | Bluetooth audio SoC with integrated GPS assist (not standalone baseband); uses external GPS module via UART. | Targeted at Bluetooth speaker/headset designs needing coarse location for geo-fencing-not suitable for precision navigation or PNDs. | Select only for Bluetooth-centric products where GPS is secondary and low-cost co-location matters more than accuracy or TTFF. |
Compared with u-blox UBX-M8030 and Qualcomm QCC3071, the STA2058 uniquely combines GPS baseband processing, ARM7 application execution, and full firmware storage in one die-eliminating host dependency while delivering best-in-class cold-start TTFF and autonomous accuracy for cost-constrained PNDs and trackers.

FAQ
What is the difference between STA2058 and STA2058EX variants?
The STA2058EX adds External Memory Interface (EMI) support and uses the LFBGA144 package, enabling connection to up to 64 Mbit of external SRAM, Flash, or ROM. Standard STA2058 (LQFP64) lacks EMI and has fewer GPIOs. Both share identical GPS engine performance, CPU, and embedded memory.
Does STA2058 support Galileo or GLONASS signals?
No. The STA2058 is a GPS-only baseband IC designed for L1 C/A code reception. It supports SBAS augmentation (WAAS/EGNOS) but does not process Galileo E1, GLONASS L1, or BeiDou B1 signals. Multi-constellation capability requires newer platforms like ST's Teseo III.
Can STA2058 operate without an external crystal?
No. The STA2058 requires a 32.768 kHz crystal on RTCXTI/RTCXTO for real-time clock functionality and a main system clock source (typically 26 MHz or 32 MHz) for the PLL. Internal RC oscillators are not provided; all timing depends on external crystals or oscillators.
Is the embedded Flash field-programmable in-system?
Yes. The 256 KB + 16 KB Flash supports in-system programming via JTAG or UART bootloader. Erase cycles are rated at 10 K for Bank 0 and 100 K for Bank 1 sectors, enabling field firmware updates and customization of NMEA output formats or interface protocols.
