# STM32WL33KBV7 (Component)

## Description

Sub\-GHz Wireless Microcontroller SoC – Arm Cortex\-M0\+ microcontroller with integrated sub\-GHz RF transceiver for low\-power wireless applications\. The STMicroelectronics STM32WL33KBV7 operates at up to 64 MHz with 128 KB Flash and 32 KB SRAM, supporting RF operation in the 413–479 MHz and 826–958 MHz bands\. It supports 2\(G\)FSK, 4\(G\)FSK, ASK/OOK, D\-BPSK, and DSSS modulation, data rates up to 600 kbps, and programmable transmit power up to \+20 dBm\. Interfaces include I²C, SPI, UART/USART, GPIO, and integrated peripherals including a 12\-bit 8\-channel ADC, DAC, RTC, timers, AES\-128, and RNG\. Supply voltage is 1\.7–3\.6 V, with operation from −40°C to \+105°C, in a 32\-pin VFQFPN 5 × 5 mm package\.
