STM32L432KBU6 MCU Description
The STM32L432KBU6microcontrollers are ultra-low-power devices based on the high-performance Arm? Cortex?-M4 32-bit RISC processor working at up to 80 MHz. The Cortex-M4 core includes a single-precision floating-point unit (FPU) that supports all Arm? single-precision data-processing instructions and data formats. It also has a complete set of DSP instructions and a memory protection unit (MPU) to improve program security. The STM32L432KBU6 provides high-speed memories (up to 256 Kbytes of flash memory and 64 Kbytes of SRAM), a Quad SPI flash memories interface, and a wide range of upgraded I/Os and peripherals connected to two APB buses, two AHB buses, and a 32-bit multi-AHB bus matrix.
