STM32L433CCU3 Description

The STM32L433CCU3 are ultra-low-power microcontrollers built on the powerful 32-bit RISC Arm? Cortex?-M4 core that operates at up to 80 MHz. A floating point unit (FPU) single precision is a characteristic of the Cortex-M4 core that supports all Arm? single-precision data-processing instructions and data formats. Additionally, it incorporates a memory protection unit (MPU) that improves program security together with the whole range of DSP instructions. A wide variety of enhanced I/Os and peripherals connected to two APB buses, two AHB buses, and a 32-bit multi-AHB bus matrix are included in the STM32L433CCU3 along with high-speed memories (Flash memory up to 256 Kbyte, 64 Kbyte of SRAM), a Quad SPI Flash memories interface (available on all packages), and these features.

The STM32L433CCU3 incorporates a number of protection methods, including a readout protection, write protection, proprietary code readout protection, and firewall, for embedded Flash memory and SRAM.

A fast 12-bit ADC (5 Msps), two comparators, an operational amplifier, two DAC channels, an internal voltage reference buffer, a low-power RTC, one general-purpose 32-bit timer, one 16-bit PWM timer specifically designed for motor control, four general-purpose 16-bit timers, and two 16-bit low-power timers are all features of the STM32L433CCU3.

Furthermore, there are up to 21 capacitive sensing channels available. Additionally, the devices include an internal step-up converter and an integrated LCD driver 8x40 or 4x44.
