    The Galaxy SmartTag 2, which was announced a couple of weeks ago alongside the Galaxy S23 FE, is now on sale in a few countries. The new object location tracker brings several improvements, including a sleeker and tougher design, longer wireless range, and longer battery life, and most of these improvements come from a new chip, which has now been revealed.

    Galaxy SmartTag 2 uses an Atomsic ATM3325 IoT chip

    Some new videos shed light on the processor that is the brain behind the Galaxy SmartTag 2. The location tracker uses Atomsic's ATM3325-5LCAQK-SR chip, which has been developed for IoT devices. Atomsic is a US-based fabless semiconductor chip firm that makes chips for IoT (Internet of Things) devices.

    Atomsic ATM33 SiC

    The ATM33 series chip used inside the Galaxy SmartTag 2 is a SiC (System In A Package) with Bluetooth 5.3 LE connectivity, an ARM Cortex M33F processor, 128KB RAM, 64KB ROM, 512KB nonvolatile memory, and ARM TrustZone security, and integrated power management. It is designed to consume extremely low power; no wonder the Galaxy SmartTag 2's battery life has improved by 66% (133% in power saving mode) compared to the Galaxy SmartTag.

    Galaxy SmartTag 2 teardown video

    A new teardown video of the Galaxy SmartTag 2 has been published on YouTube. It shows how small the location tracker actually is, given that half of the device's body is taken up by its ring. The other half includes the chips, the motherboard, and the battery. The two halves of the body are glued together, while the CR2032 battery can be removed by inserting a pin in the pinhole.
