ING91870CQ Chip Overview

The ING91870CQ is AEC-Q100 Grade 2 certified. It integrates a fully compliant low-power Bluetooth 5.1 protocol standard with complete proprietary IP, including Modem, Link Layer Controller, and Host. It also features a high-performance 32-bit RISC MCU, built-in 512KB flash, low-power PMU, various peripheral interfaces, and high-performance low-power Bluetooth RF. The transmission power of the ING91870CQ ranges from -28dBm to +6.5dBm, with a sensitivity of -102dBm in LR S8 mode and -97dBm in 1M mode.

The ING91870CQ provides a fully open SDK, supporting IDE platforms such as Keil, IAR, and Segger, as well as development languages like C, C++, and Nim. It supports the three major operating systems: Windows, Linux, and MacOS, and includes a graphical project wizard and data editor, with over 30 open-source software application examples embedded.

The ING91870CQ can be customized through hardware and software development to adapt to various applications, such as smart automotive applications, ultra-low power applications, precise positioning, and industrial interconnectivity.
