Overview
AG3335M series is a highly integrated System-in-Package (SiP), low-power, RFSoC GPS receiver with an application processor, GPS L1 and L5 receiver, a power management unit (PMU) and a 4MB flash.
AG3335M series contains an ARM® Cortex®-M4F application processor that can operate in a range of frequencies between 26MHz and 530MHz, and achieve high performance and power efficiency with Level one cache (L1 cache).
The GPS subsystem contains the RF and baseband circuits, which are able to track L1+L5 satellites at the same time, and search GPS satellites using the L1 circuit.
The PMU contains five ultra-low quiescent current low-dropout linear regulators (LDO) to provide a stable power source for the internal and external devices.

The SiP package technology combine the main die, PMU and flash. This significantly reduces the product size and provides more features in the same space.
