STM32L151R8H6 - Brand New STMicroelectronics Microcontrollers
-
Description
The STM32L151R8H6 is an electronic component model in the category of microcontrollers. It is equipped with the ultra-low-power STM32L15xxx series which combines the connectivity power of the universal serial bus (USB) with the high-performance ARM Cortex™-M3 32-bit RISC core. This microcontroller operates at a frequency of 32 MHz and features a memory protection unit (MPU), high-speed embedded memories, and an extensive range of enhanced I/Os and peripherals. With a 12-bit ADC, 2 DACs, and 2 ultra-low-power comparators, as well as timers and communication interfaces like I2C, SPI, USART, and USB, the STM32L151R8H6 provides a comprehensive set of features for various applications. It also includes capacitive sensing channels, a real-time clock, and a built-in LCD controller. Operating within a wide temperature range and supporting power-saving modes, this microcontroller is ideal for low-power applications.
