ARM MCU, STM32 Family STM32L4 Series Microcontrollers, ARM Cortex-M4, 32 bit, 80MHz, 512 KBProduct OverviewThe STM32L452RET6 from STMicroelectronics is a STM32L452xx series ultra-lowpower ARM Cortex-M4 32bit microcontroller with floating point unit (FPU) in 64pin LQFP package. The Cortex-M4 core features a FPU single precision whichsupports 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 device embeds high speed memories(512Kbyte flash memory, 160Kbyte of SRAM), quad SPI flash memories interface andan extensive range of enhanced I/Os and peripherals connected to 2 APB buses, 2AHB buses and 32bit multi-AHB bus matrix. It features 1 (16bit) advancedcontrol, 2 (16bit)/1 (32bit) general purpose, 2 (16bit) basic, 2 (16bit) lowpower, 1 SysTick and 2 watchdog timers. It also features 2 tamper pins, randomgenerator, 52 GPIOs, 4 wakeup pins, 12 capacitive sensing channels, one 12bitADC (16 ch), one 12bit DAC, 2 comparator and 1 op-amp.Ultra-low power with FlexPowerControl, 80MHz maximum CPU frequency1.71V to 3.6V power supply, -40°C to 85°C operating temperature rangeThree SPI, Four I2C, three USART, UART, LPUART, SAI, CAN, USB FS, SDMMCinterface14-channel DMA controller and RTC with HW calendar, alarms, calibration4 to 48MHz crystal oscillator, 32KHz crystal oscillator for RTC (LSE)Internal 16MHz factory trimmed RC (±1%), energy benchmark (245 ULPBench® score)Brown out reset (BOR), 4µs wakeup from stop mode, batch acquisition mode (BAM)True random number generator, CRC calculation unit, 96bit unique IDSerial wire debug (SWD), JTAG, Embedded Trace Macrocell supportReadout protection, write protection, proprietary code readout protection andFirewallApplicationsEmbedded Design & DevelopmentProduct InformationProduct Range: STM32 Family STM32L4 Series MicrocontrollersDevice Core: ARM Cortex-M4No. of Bits: 32bitData Bus Width: 32bitOperating Frequency Max: 80MHzCPU Speed: 80MHzProgram Memory Size: 512KBRAM Memory Size: 160KBIC Case / Package: LQFPNo. of Pins: 64PinsMCU Case Style: LQFPNo. of I/O's: 52I/O'sInterfaces: CAN, I2C, SPI, UART, USART, USBEmbedded Interface Type: CAN, I2C, SPI, UART, USART, USBSupply Voltage Min: 1.71VSupply Voltage Max: 3.6VMCU Family: STM32MCU Series: STM32L4MSL: MSL 3 - 168 hours
