BLUENRG-332AT

RF Transceiver ICS Overview

The BLUENRG-332AT is a programmable Bluetooth Low Energy 5.3 Wireless System-on-Chip (SoC) manufactured by STMicroelectronics. It integrates an ARM Cortex-M0 core with a 2.4 GHz radio supporting data rates up to 2 Mbps and an output power of 8 dBm. The device features -97 dBm sensitivity, operates on a supply voltage range of 1.7 V to 3.6 V, and consumes 3.4 mA during reception and 4.3 mA during transmission. Memory resources include 192 kB of program memory and 12 kB of SRAM. It includes an 8-channel 12-bit ADC and supports interfaces such as I2C, SPI, LPUART, USART, and GPIO. The component is available in WLCSP-36 and QFN-32 packages and functions within a temperature range of -40°C to +105°C.

RF Transceiver ICS Procurement Notes

Verify the specific package variant required, as the BLUENRG-332 series includes both WLCSP-36 and QFN-32 options which are not functionally interchangeable due to pinout differences. Confirm that the selected part number corresponds to the intended enclosure type before ordering. Ensure compatibility with the chosen antenna design and PCB layout constraints associated with the specific package geometry.

RF Transceiver ICS Selection Notes

Select this component when Bluetooth 5.3 compliance and low power consumption are critical requirements. The integration of the ARM Cortex-M0 allows for flexible firmware implementation without external microcontrollers. Consider the available memory sizes against application complexity. Evaluate the operating temperature range to ensure suitability for the intended environmental conditions.

RF Transceiver ICS Part Context

This SoC belongs to the BlueNRG family of wireless solutions from STMicroelectronics. It is designed to replace discrete Bluetooth transceivers and microcontrollers by integrating both functions into a single chip. The series offers various package options to accommodate different size and cost constraints in compact electronic designs.

RF Transceiver ICS Replacement Considerations

The BLUENRG-332VT is a related variant within the same product family. Verify package compatibility and pin mapping if substituting between AT and VT suffixes.
