Shenzhen Meiyuxin Technology Co., Ltd. [distributing ST products] sells original STM32WBA52CEU6 ultra-low power consumption, Arm Cortex-M33 TZ MCU 100 MHz with 1MB flash memory, BT LE 5.2 quality assurance Brand new original! !

Product Description:

The STM32WBA52CEU6 long-range wireless and ultra-low-power device embeds a powerful and ultra-low-power LPWAN-compatible radio solution supporting the following modulations: LoRa®, (G)FSK, (G)MSK and BPSK. LoRa® modulation is only available in STM32WLx5xx.

The devices are designed for extremely low power consumption and are based on a high-performance Arm® Cortex®-M4 32-bit RISC core running at frequencies up to 48 MHz. The core implements a full set of DSP instructions and an independent memory protection unit (MPU), enhancing application security. These devices embed high-speed memory (Flash up to 256 KB, SRAM up to 64 KB), and a wide range of enhanced I/O and peripherals.

These devices also embed several protection mechanisms for the embedded flash and SRAM: read protection, write protection, and proprietary code read protection. These devices provide a 12-bit ADC, a 12-bit DAC low-power track-and-hold, two ultra-low-power comparators associated with a high-precision voltage reference generator.

These devices embed a low-power RTC with a 32-bit sub-second wake-up counter, a 16-bit single-channel timer, two 16-bit quad-channel timers (supporting motor control), a 32-bit quad-channel timer and Three 16-bit ultra-low power timers. The devices also embed two DMA controllers (7 channels each), allowing any combination between transfer memory (Flash, SRAM1 and SRAM2) and peripherals, using DMAMUX1 for flexible DMA channel mapping.

The devices also feature the following standard and advanced communication function interfaces: two USARTs (supports LIN, smart card, IrDA, modem control, and ISO7816), one low-power UART (LPUART), three I2C (SMBus/PMBus), two SPI (up to 16 MHz, one supporting I2S), a semaphore used for process synchronization of the processor firmware. Operating temperature/voltage range is –40 °C to +105 °C (+85 °C for radio) from a 1.8 V to 3.6 V supply. A comprehensive set of power-saving modes allows the design of low-power applications.

The device integrates a high-efficiency SMPS step-down converter and independent supplies to power the ADC, DAC, and comparator analog inputs. VBAT dedicated power supply allows LSE 32.768 kHz oscillator, RTC and backup registers to be backed up. The device can maintain these functions even if the main VDD is disconnected, through a battery like CR2032, a super capacitor or a small rechargeable battery
