MT3303

High performance, automotive grade 3 chip with autonomous discovery of multi-GNSS

A high-performance, single-chip, multi-GNSS solution designed for automotive grade 3 applications (-40C to +85C). The chip includes on-chip CMOS RF, digital baseband, ARM7 CPU and embedded NOR flash. This chip can achieve the industry's highest level of sensitivity, accuracy and Time to First Fix (TTFF) with the lowest power consumption, all in a small-footprint lead-free package. Its small footprint and minimal BOM requirement provide significant reductions in the design, manufacturing and testing resource required for portable applications.
