2 DESCRIPTION

■ SPI

STA2056 is one chip GPS featuring the complete

RF for active antenna systems and baseband

functionality in a QFN 68pin package. STA2056

System-on-Chip combines GPS performances

with low power consumption. Thanks to the few

external components STA2056 makes the appli-

cation simple and smaller.

■ CAN 2.0 B active

■ External Memory Interface

(in TQFP176 package, development only)

1.4 Operating Temperature

■ -40°C +85°C
