STM32WL33KBV6TR

RF Transceiver ICS Overview

The STM32WL33KBV6TR is a system-on-chip integrating an Arm Cortex-M0+ MCU and a sub-GHz radio. It features 64 kB Flash, 16 kB SRAM, and operates at up to 64 MHz. The radio supports frequencies of 413–479 MHz and 826–958 MHz with 20 dBm output power. Key protocols include 802.15.4, Sigfox, KNX, and LoRaWAN. It offers -132 dBm sensitivity and interfaces via SPI, I2C, USART, and GPIO.

RF Transceiver ICS Feature Summary

• Integrates ultra-low-power sub-GHz radio with single-core ARM Cortex-M0+ processor
• Supports multiple modulation schemes including GFSK, FSK, OOK, and DSSS for diverse protocol compatibility
• Includes internal LCD driver and LC sensor controller for direct peripheral interfacing

RF Transceiver ICS Applications

• Smart metering and utility automation
• Industrial wireless sensor networks
• Home automation and smart lighting systems
• Long-range IoT tracking devices

RF Transceiver ICS Procurement Notes

Verify the specific memory configuration (64 kB Flash/16 kB RAM) against project requirements, as this variant differs from higher-capacity models in the STM32WL33xx series. Confirm package type 32-VFQFPN availability and ensure ESD protection measures are implemented during handling due to the sensitive RF components integrated on the die.

RF Transceiver ICS Selection Notes

Select this component when board space is limited and a combined MCU-radio solution is required. It is suitable for applications needing moderate processing power alongside long-range connectivity. Compare against STM32WL33K8V6TR if larger memory capacity is needed, or consider STM32WL5x series for LoRa-specific optimizations.

RF Transceiver ICS Part Context

This part belongs to the STM32WL33xx family, designed for efficiency-focused wireless applications. It complements the broader STM32WL portfolio by offering a cost-effective SoC for proprietary protocols and standard LPWAN implementations without requiring external transceivers.

RF Transceiver ICS Replacement Considerations

STM32WL33K8V6TR offers increased memory but shares similar RF capabilities. STM32WL33CCV6TR provides higher memory and more GPIOs. Ensure pinout compatibility when substituting within the WL33xx series.
