STM32WL55CCU6 ARM-Cortex®-M4+M0 MCU, 32 bit, 1.8-3.6 V, 256 KB,UFQFPN-48

Multiprotocol LPWAN Dual-Core 32-bit Arm® Cortex®-M4/M0+ LoRa®, (G)FSK, (G)MSK, BPSK, up to 256KB Flash, 64KB SRAM

Description: The STM32WL55/54xx long-range wireless and ultra-low-power devices contain a powerful and ultra-low-power LPWAN compliant radio solution that enables the following modulations: LORA®, (G)FSK, (G)MSK, and BPSK. LoRa® modulation is only available in the STM32WLx5xx. These devices are designed to be extremely energy efficient and are based on the powerful ARM® Cortex®-M4 32-bit RISC core, which operates at a frequency of up to 48 MHz. This core implements a full set of DSP commands. It is complemented by an ARM® Cortex®-M0+ microcontroller. Both cores implement an independent Memory Protection Unit (MPU) that increases application security.
