Ultra-Low Consumption System for IoT Smart Wearables- GAOTek

Description

Overview

FU2625-2 is a UWB-TAG module based on the latest UWB chip design, equipped with 2 units of PCB high-performance monopole antenna and 1 unit of inverted F Bluetooth antenna. The FU2625-2 integrates antenna, RF circuits, power management and clock circuits. The UWB can work in SS-TWR ranging or DS-TWR ranging modes, and work with the base station to perform TDOA positioning demonstration, 2DAOA, 3DAOA demonstration, with a positioning accuracy of up to 10 cm. The UWB chip supports 850 Kbps, 6.8 Mbps, 7.8  Mbps, 27.2 Mbps, and 31.2 Mbps data rates (default 850 Kbps). The UWB chip supports the Basic Pulse Repetition Frequency (BPRF) mode 64 MHz Peak Repeat Frequency and Higher Pulse Repetition Frequency (HPRF) modes with 124.8 M and 249.6 MHz Peak Pulse Repetition Frequency. The chip supports Safe Ranging Sequence (STS) based on scrambled time stamps. This module also integrates a low-power Bluetooth 5.3 chip, including Modem, Link Layer Controller and Host. It also integrates a high-performance 32-bit RISC MCU with DSP and FPU functions, a built-in 512KB f1ash, a low-power PMU, a variety of peripheral interfaces, and high-performance and low-power Bluetooth RF. Transmit power from -30 dBm to +8 dBm, receive sensitivity is –102 dBm at LR S8 mode, -96 dBm at 1M mode.
