STM32WL33K8V6

RF Transceiver ICS Overview

The STM32WL33K8V6 is a multiprotocol system-on-chip integrating an Arm Cortex-M0+ microcontroller and a sub-GHz radio transceiver. It features 64 kB of flash memory and 16 kB of SRAM, operating at a maximum clock frequency of 64 MHz. The device supports frequencies from 413 MHz to 479 MHz and 826 MHz to 958 MHz with a transmit power up to 20 dBm. It offers sensitivity of -132 dBm and supports protocols including 802.15.4, KNX, LPWAN, Sigfox, and Zigbee. Powered by 1.7 V to 3.6 V, it operates between -40°C and 85°C in a 32-VFQFN package.

RF Transceiver ICS Feature Summary

• Integrates a low-power microcontroller with a long-range energy-efficient sub-GHz radio on a single chip for multiprotocol support.
• Supports multiple modulation schemes including 2/4 (G)FSK, ASK, D-BPSK, and DSSS for flexible wireless application design.
• Includes hardware security features such as AES-128 encryption and cryptographic accelerators for secure data transmission.

RF Transceiver ICS Applications

• Smart home automation systems requiring KNX or Zigbee connectivity
• Long-range wireless sensor networks utilizing LPWAN protocols
• Industrial IoT devices supporting Sigfox or proprietary sub-GHz communication

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'V6' corresponds to the 64 kB flash and 16 kB RAM configuration when ordering. Confirm that the 32-VFQFN exposed pad package matches the target PCB footprint requirements. Ensure the selected variant aligns with the required frequency bands for the intended market region. Cross-reference the datasheet revision date to confirm current manufacturing status and any potential errata updates before finalizing procurement.

RF Transceiver ICS Selection Notes

Select this component when a combined MCU and RF solution is needed to reduce bill-of-materials count. It is suitable for applications requiring support for multiple wireless standards without separate transceiver chips. Consider the 64 MHz processing speed sufficient for protocol stack execution. Evaluate the 20 dBm output power against the required link budget for the deployment environment.

RF Transceiver ICS Part Context

This part belongs to the STM32WL33xx series, designed for efficiency in sub-GHz wireless applications. It utilizes the Cortex-M0+ core architecture optimized for low-power consumption. The series complements other STM32WL variants by offering specific memory configurations tailored for cost-sensitive yet performance-capable wireless endpoints.

RF Transceiver ICS Replacement Considerations

The STM32WL33K8V6TR is the tape-and-reel version of this component. Other members of the STM32WL33xx family may offer different flash sizes or pin counts but share similar architectural features.
