Shenzhen Meiyuxin Technology Co., Ltd. [distributing ST chips] STM32L452RCI6 ARM microcontroller - MCU Ultra-low-power FPU Arm Cortex-M4 MCU Quality assurance New original! ! !

Product Description:

The STM32L452RCI6 device is based on the high-performance Arm® Cortex®-M4 32-bit RISC core running at frequencies up to 80 MHz. The Cortex-M4 core features floating-point unit (FPU) single precision and supports all Arm® single-precision data processing instructions and data types. It also implements a complete set of DSP instructions and a memory protection unit (MPU), which enhances application security.

The STM32L452RCI6 device embeds high-speed memory (up to 512 KB Flash, 160 KB SRAM), a Quad SPI Flash interface (for all packages) and extensive enhanced I/O and peripherals connected to two APB buses, two AHB bus and a 32-bit multi-AHB bus matrix.

The STM32L452RCI6 devices embed several protection mechanisms for the embedded Flash memory and SRAM: read protection, write protection, proprietary code read protection and firewall. These devices provide a fast 12-bit ADC (5 Msps), two comparators, an operational amplifier, a DAC channel, an internal voltage reference buffer, a low-power RTC, a general-purpose 32-bit timer, a dedicated motor Controlled 16-bit PWM timer, four general-purpose 16-bit timers and two 16-bit low-power timers. Additionally, up to 21 capacitive sensing channels are available.

STM32L452RCI6 They also have standard and advanced communication interfaces, namely four I2C, three SPI, three USART, one UART and one low-power UART, one SAI, one SDMMC, one CAN, one USB full-speed device crystal less. The STM32L452RCI6 device embeds an AES hardware accelerator.

The STM32L452RCI6 has an operating temperature range of -40 to +85 °C (+105 °C junction) and -40 to +125 °C (+130 °C junction) with a 1.71 to 3.6 V supply. A comprehensive set of power-saving modes enables the design of low-power applications. Partial independent power support: analog independent power input ADC, DAC, OPAMP and comparator. VBAT input can backup RTC and backup registers. The STM32L452RCI6 series is available in seven packages ranging from 48 to 100-pin packages.
