STM32WB09KEV7TR

RF Transceiver ICS Overview

The STM32WB09KEV7TR is an ultra-low-power RF System on a Chip featuring an ARM Cortex-M0+ core operating at 64 MHz. It integrates 512 Kbytes of Flash and 16 Kbytes of SRAM with Bluetooth LE 5.4 support. The device operates within a voltage range of 1.7 V to 3.6 V, consuming 3.6 mA during reception and 4.9 mA during transmission. It provides 8 dBm output power and -104 dBm sensitivity at 2 Mbps data rates. The component includes an 8-channel 12-bit ADC and interfaces such as GPIO, I2C, SPI, and UART. It is housed in a VFQFPN-32 package and functions within temperatures from -40°C to +105°C.

RF Transceiver ICS Procurement Notes

Verify the specific suffix KEV7TR against official STMicroelectronics documentation to confirm the exact pinout, package dimensions, and moisture sensitivity level. Ensure compatibility with the intended PCB layout for the VFQFPN-32 footprint. Cross-reference the Bluetooth LE version certification status required for regional regulatory compliance before finalizing procurement orders.

RF Transceiver ICS Selection Notes

Select this component when a balance of moderate program memory and low power consumption is required for Bluetooth LE applications. The 512 Kbyte Flash capacity supports complex firmware logic compared to smaller variants. The 64 MHz clock speed offers sufficient processing overhead for protocol stack handling while maintaining energy efficiency suitable for battery-operated systems.

RF Transceiver ICS Part Context

This part belongs to the STM32WB0 series, designed specifically for cost-sensitive and space-constrained wireless applications. It shares the same core architecture and radio specifications as other members of the family but differs in memory size and package type. The VFQFPN-32 package distinguishes it from WLCSP or larger QFN options available in the broader product line.

RF Transceiver ICS Replacement Considerations

Consider the STM32WB09TEF7TR for alternative packaging requirements using the 36-WLCSP format. Verify that the pinout and peripheral availability remain compatible with the existing design if substituting between different package types within the same memory configuration family.
