Description
General part information
STM32WL33KB Series
The STM32WL33xx is a high performance ultra-low power wireless application processor, intended for RF wireless applications in the sub-1 GHz band. It is designed to operate in both the license-free ISM and SRD frequency bands such as 433, 868, and 915 MHz.
It adopts a single-core architecture embedding an Arm® 32-bit Cortex®-M0+ CPU that can operate up to 64 MHz. It integrates high-speed and flexible memory types: up to 256 Kbyte flash memory, and up to 32 Kbyte RAM, one-time programmable (OTP) memory area of 1 Kbyte.
The STM32WL33xx embeds a wide set of peripherals, including a 20-pin (16 segments + 4 commons) LCD driver, 12-bit, 8 channel ADC, analog comparator, DAC, LC sensor controller, RTC, IWDG, general purpose timers, AES-128, RNG, CRC, communication interfaces such as USART, SPI, and I2C. Moreover, the security features enable secure boot with USART/SWD block (write protection) and sensitive information storage in flash (read-out protection).
