BLUENRG-MSQTR

RF Transceiver ICS Overview

The BLUENRG-MSQTR is a Bluetooth Low Energy network processor from STMicroelectronics, compliant with the Bluetooth 4.2 core specification. It integrates an ARM Cortex-M0 core operating at a maximum clock frequency of 32 MHz, paired with 64 kB of program memory and 12 kB of data RAM. The device operates within a supply voltage range of 1.7 V to 3.6 V and supports frequencies from 2.4 GHz to 2.4835 GHz. It features no ADC and is housed in a QFN-32 package.

RF Transceiver ICS Feature Summary

• Supports simultaneous multi-role operation as both a BLE sensor and hub device
• Integrates embedded BLE protocol stack including GAP, GATT, SM, L2CAP, LL, and RF-PHY on the Cortex-M0 core
• Connects to host microcontrollers via a dedicated SPI-based interface for low power consumption

RF Transceiver ICS Applications

• Smart devices powered by coin cell batteries requiring long operational life
• Bluetooth LE sensor nodes acting as peripheral devices
• BLE hub applications functioning as central or bridge devices
• Evaluation platforms utilizing external STM32L microcontrollers for firmware development

RF Transceiver ICS Procurement Notes

Verify component status carefully as this part number may be marked as Not Recommended for New Designs (NRND). Confirm that the QFN-32 package variant aligns with your PCB layout requirements. Ensure compatibility with the host MCU's SPI interface specifications before finalizing procurement decisions.

RF Transceiver ICS Selection Notes

Select this component when designing systems requiring a standalone BLE network processor with minimal external components. It is suitable for applications needing integrated protocol handling without complex software stacks on the host. Consider the 1.7V to 3.6V operating range for battery-powered designs and verify that the host system can support the required SPI communication speeds.

RF Transceiver ICS Part Context

The BLUENRG-MSQTR belongs to the BlueNRG-MS family of ultra-low-power Bluetooth Smart processors. These devices are designed to offload BLE connectivity tasks from main application processors, thereby extending battery life in portable electronics. The series supports various packaging options including WLCSP and QFN to accommodate different form factors.

RF Transceiver ICS Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult official STMicroelectronics resources for current lifecycle updates or alternative recommendations if this NRND part is unsuitable.
