High performance processing: 64MHz ARM Cortex-M4F CPU with FPU, 1MB Flash and 256KB RAM
Ultra-low power consumption: 1.7V to 5.5V operating voltage range, supports USB direct power supply
Enhanced security: Integrated Arm CryptoCell-310 encryption accelerator
Rich interfaces: Provide USB 2.0, SPI, I2C, UART, PDM, I2S and other peripheral interfaces.

NRF52840-QIAA Technical Highlights
1. Multi-protocol Wireless Connectivity
The dynamic multi-protocol feature of the NRF52840-QIAA supports concurrent operation of multiple wireless protocols, such as maintaining BT and Thread connectivity simultaneously. This design ensures that the radio hardware operating time is intelligently distributed among the protocols so that multiple connections do not interfere with each other. This feature makes the NRF52840-QIAA particularly suitable for complex application scenarios where different IoT protocols need to be connected at the same time, according to the technical team of Mingjiada Electronics.
2. Excellent Power Consumption
As a representative of Nordic's low-power wireless solutions, the NRF52840-QIAA adopts advanced power management technology:
Receive current is only 6.26mA and transmit current is 4.82mA (at 0dBm output)
Sensitivity up to -95dBm to ensure energy efficiency for long range communication
Integrated DC-DC buck converter to further optimise power consumption
Mingjiada Electronics emphasises that these features enable devices using the NRF52840-QIAA to achieve up to several years of battery life, making it particularly suitable for wearables and remote sensor applications.

3. Enhanced Security Features
The NRF52840-QIAA integrates the Arm TrustZone CryptoCell-310 cryptographic accelerator to provide hardware-level security enhancements, including:
AES-128 encryption
Hash functions
True random number generation
Key management
Mingjiada Electronics reminds customers that these security features make the NRF52840-QIAA fully compliant with the increasing security requirements for IoT devices, making it particularly suitable for sensitive applications such as smart payments and medical devices.
