Epson Electronics America (EEA) has launched a Global Positioning System (GPS) receiver module that consumes only 100mW at 3.3V.
Housed in a thin 7-gram package 34.8mm wide by 25.8mm deep and 6mm high, the receiver, dubbed the S4E39860, can be used in standard mobile, PC card, automotive and custom OEM applications.
The S4E39860 is a complete L1-Band world-wide GPS receiver module equipped with a built-in signal processor, SRAM, Epson’s 32-bit RISC CPU (S1C33 core) and real-time computing (RTC) capabilities.
A multi-channel feature allows for 8-channel receiving sensitivity at -130dBm with the shortest position updates in just 1 second.
Normal operating current is 30mA, but the receiver also has a power saving mode that draws a current of 3mA at 3.1V. Operating temperature range for the S4E39860 is -30 degrees to +80 degrees Celsius. Data is transferred at a rate of 9,600bps.
The new module’s acquisition time of signal allows a cold start at 190 seconds or less, a warm start at 50 seconds or less and a hot start at just 20 seconds or less. In rare cases where the reception of the satellite signal is interrupted, the S4E39860 recovers and re-establishes the connection within 2 seconds.
The S4E39860 is currently available priced at $35 in quantities of 10K or more.
