S4E39860
GPS Receiver Module
Ultra Low-Power consumption (100mW)
Compact and Thin design
Handles differential GPS
OVERVIEW
GPS (Global Positioning System) having been used Car Navigation Systems, is now going to be used in
mobile equipment as well. S4E39860 is the miniature GPS Receiver module developed for the purpose of built
in the mobile equipment based on the battery-drive. Super-low consumption electric power, compact and thin
size were realized by developing the special IC which built in Signal Processor, SRAM and RTC in the 32Bit
RISC- CPU (SEIKO EPSON original).
