Description

STA2051GO is an STMicroelectronics system-on-chip device featuring the full GPS

controller functionality. It combines a high performance ARM7TDMI microprocessor with

embedded high-speed single voltage FLASH and static RAM with enhanced peripherals and

I/O capabilities. It also provides clock generation via PLL.

STA2051GO is software compatible with the ARM processor family. The device has an on-

chip voltage regulator for the 1.8V core logic supply but 3.3V capable I/O lines.
