MediaTek MT3333 is a high-performance single-chip multi-GNSS solution that includes CMOS RF, digital baseband, ARM7 CPU and embedded NOR flash. It’s able to achieve the industry’s highest level of sensitivity, accuracy and Time-to-First-Fix (TTFF) with the lowest power consumption. Its small footprint lead-free package and minimal additional BOM requirements provide significant reductions in the design, manufacturing and testing resources required to create devices.
