ARM MCU, Ultra Low Power, STM32 Family STM32L1 Series Microcontrollers, ARMCortex-M3, 32 bitProduct OverviewThe STM32L151C8T6A is an ultra-low-power STM32 L1 series 32-bit Microcontrollerincorporates the connectivity power of the universal serial bus (USB) with thehigh-performance ARM Cortex-M3 RISC core operating at a frequency of 32MHz (33.3DMIPS). It features a memory protection unit (MPU), high-speed embedded memories(Flash memory up to 64kB and RAM up to 16KB) and an extensive range of enhancedI/Os and peripherals connected to two APB buses. The devices offer one 12-bitADC, two DACs, two ultra-low-power comparators, six general-purpose 16-bittimers and two basic timers, which can be used as time bases. The device containstandard and advanced communication interfaces - two I²Cs, two SPIs, threeUSARTs and an USB.1.25 DMIPS/MHz (Dhrystone 2.1)Ultra-safe, low-power BOR (brownout reset) with 5 selectable thresholdsUltralow-power POR/PDRProgrammable voltage detector (PVD)1 to 24MHz Crystal oscillator32kHz Oscillator for RTC with calibrationHigh-speed internal 16MHz factory-trimmed RC (±1%)Internal low-power 37kHz RCInternal multispeed low-power 65kHz to 4.2MHz clockPLL for CPU clock and USB (48MHz)Pre-programmed bootloader - USART supportedSerial wire debug supportedJTAG and trace supported7-channel DMA Controller2 x Watchdog timers (Independent and window)Up to 20 capacitive sensing channels supporting touch key, linear and rotarytouch sensorsCRC calculation unit96-bit Unique IDApplicationsMedical, Portable Devices, Automation & Process Control, Computers & ComputerPeripherals, Communications & Networking, Sensing & Instrumentation, Metering,Imaging, Video & Vision, SecurityProduct InformationProduct Range: STM32 Family STM32L1 Series MicrocontrollersDevice Core: ARM Cortex-M3No. of Bits: 32bitData Bus Width: 32bitOperating Frequency Max: 32MHzCPU Speed: 32MHzProgram Memory Size: 64KBRAM Memory Size: 32KBIC Case / Package: LQFPNo. of Pins: 48PinsMCU Case Style: LQFPNo. of I/O's: 37I/O'sInterfaces: I2C, SPI, USART, USBEmbedded Interface Type: I2C, SPI, USART, USBSupply Voltage Min: 1.8VSupply Voltage Max: 3.6VMCU Family: STM32MCU Series: STM32L1MSL: MSL 3 - 168 hours
