STM32L452CEU3 General Description
The STM32L452xx devices are ultra-low-power microcontrollers based on the high-performance Arm®Cortex®-M4 32-bit RISC core operating at a frequency of up to 80 MHz. The Cortex-M4 core features a Floating point unit (FPU) single precision that supports all Arm®single-precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security.The STM32L452xx devices embed high-speed memories (Flash memory up to 512 Kbyte, 160 Kbyte of SRAM), a Quad SPI Flash memories interface (available on all packages) and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix.The STM32L452xx devices embed several protection mechanisms for embedded Flash memory and SRAM: readout protection, write protection, proprietary code readout protection and Firewall.The devices offer a fast 12-bit ADC (5 Msps), two comparators, one operational amplifier, one DAC channel, an internal voltage reference buffer, a low-power RTC, one general-purpose 32-bit timer, one 16-bit PWM timer dedicated to motor control, four general-purpose 16-bit timers, and two 16-bit low-power timers.In addition, up to 21 capacitive sensing channels are available.They also feature standard and advanced communication interfaces, namely four I2Cs, three SPIs, three USARTs, one UART and one Low-Power UART, one SAI, one SDMMC, one CAN, one USB full-speed device crystal less.The STM32L452xx operates in the -40 to +85 °C (+105 °C junction) and -40 to +125 °C (+130 °C junction) temperature ranges from a 1.71 to 3.6 V VDDpower supply when using internal LDO regulator and a 1.05 to 1.32V VDD12power supply when using external SMPS supply. A comprehensive set of power-saving modes makes possible the design of low-power applications.Some independent power supplies are supported: analog independent supply input for ADC, DAC, OPAMP and comparators. A VBAT input makes it possible to backup the RTC and backup registers. Dedicated VDD12power supplies can be used to bypass the internal LDO regulator when connected to an external SMPS.The STM32L452xx family offers seven packages from 48 to 100-pin packages.STM32 Nucleo-64 development board with STM32L452.STM32 Nucleo-64 development board with STM32L452.LTE Cellular to Cloud Pack with STM32L496AG MCU.Evaluation board with STM32L476ZG MCU.ST-LINK/V2 in-circuit debugger/programmer for ST.
