STA2051

Overview

The STA2051 is a 32-bit single-chip baseband controller designed for GPS and telematic applications. It integrates an ARM7TDMI RISC CPU with 256 KB of Flash and 64 KB of RAM, alongside a 12-channel GPS correlation DSP supporting RTCA-SC159, WAAS, and EGNOS standards without requiring a TCXO. The device operates within a -40°C to 85°C temperature range and features multiple communication interfaces including CAN, UART, SPI, I2C, and USB V1.1 (TQFP144 only). Power supplies include 2.7V–3.6V for I/O, 3V for the ADC reference, and 1.8V for the core.

Feature Summary

ARM7TDMI 16/32-bit RISC CPU host microcontroller
12-channel GPS correlation DSP with no TCXO requirement
Integrated memory: 256 KB Flash and 64 KB RAM
Comprehensive connectivity: CAN, UART, SPI, I2C, and USB

Applications

Automotive telematics systems
GPS navigation devices
Vehicle tracking solutions

Procurement Notes

Verify package availability when ordering. The component is available in TQFP64 and TQFP144 packages. Standard packing options include trays and tape-and-reel formats depending on the specific order code suffix selected by the purchaser.

Selection Notes

Select the TQFP144 package if USB V1.1 interface functionality is required, as this peripheral is exclusive to that variant. Ensure power supply design accommodates the distinct voltage domains: 2.7V–3.6V for peripherals, 3V for the ADC reference, and 1.8V for the core logic.

Part Context

This component serves as a dedicated baseband controller for positioning and data transmission. It combines processing capabilities with specialized digital signal processing for satellite navigation, eliminating the need for external timing oscillators in many configurations.

Replacement Considerations

No public confirmed substitute part numbers are documented in the provided datasheet. Designers should evaluate pin compatibility and software architecture requirements before considering alternative components from other manufacturers.
