Introduction

The IS1870/71 SoC contains a 2.4 GHz transceiver, a Power Management Unit (PMU), Bluetooth Low Energy software stack and an RF power amplifier. The default factory configuration is designed to work with a host MCU to provide the user with an embedded Bluetooth Low Energy design setup for the IoT application domain. The IS1870/71 SoC provides:

• Simple integration and programming
• Reduced development time
• Superior Bluetooth Low Energy solution with low-cost system
• Interoperability with Apple iOS and Android OS
• Wide range of application support With the default factory configuration, the IS1870/71 SoC supports Beacon technology, where the automation of Bluetooth Low Energy connection/control and cloud connectivity are common. The IS1870/71 SoC is optimized to maintain a low power wireless connection. The low power consumption and flexible power management maximize the IS1870/71 SoC lifetime in battery operated devices. A wide operating temperature range enables its applications in indoor and outdoor environments (industrial temperature range is -40°C to +85°C). The small form factor package size of the IS1870/71 SoC is designed for wearable applications. The solution providers can minimize the module size to meet the market requirements, which is commonly seen in the IoT application domain. To operate in the 2.4 GHz ISM band radio, the IS1870/71 SoC is certified for the Bluetooth v5.0 core specification, including support for the enhanced throughput and the Federal Information Processing Standard (FIPS) compliant encryption support for secure data connections. The IS1870/71 SoC integrates transceiver and baseband functions to decrease external components. Free Bluetooth stack firmware is provided to build an embedded Bluetooth Low Energy solution, using the IS1870/71 SoC.
