STM32L151C8T6A MCU ARM Cortex-M3 Microcontroller
The STM32L151C8T6A from STMicroelectronics is a high-performance, ultra-low-power 32-bit microcontroller based on the ARM Cortex-M3 core, operating at frequencies up to 32 MHz (33.3 DMIPS) . Housed in a compact 48-pin LQFP package (7x7mm), this device is a cornerstone of the STM32L1 series, designed specifically for battery-operated and energy-sensitive applications . It integrates 64 KB of Flash memory with ECC, 32 KB of SRAM, and 4 KB of true data EEPROM, providing substantial on-chip storage for code and data . The microcontroller operates from a wide supply voltage range of 1.65V to 3.6V and is rated for an industrial temperature range of -40°C to +85°C, ensuring reliable performance in diverse and demanding environments .
This microcontroller delivers an exceptional balance of processing power and energy efficiency. Its ultra-low-power platform features multiple advanced power-saving modes, including a Standby mode consuming only 0.28 µA (with 3 wakeup pins) and a Stop mode as low as 0.44 µA (with 16 wakeup lines), coupled with a rapid 8 µs wakeup time from Stop mode, enabling designs with years of battery life . The rich peripheral set includes a 12-bit ADC with up to 16 channels and 1 Msps sampling rate, two 12-bit DACs with output buffers, and two ultra-low-power comparators for precise analog signal conditioning . Communication is facilitated by a full-speed USB 2.0 interface (with internal 48 MHz PLL), three USARTs (supporting LIN, IrDA, Smart Card), two SPI ports (up to 16 Mbit/s), and two I2C interfaces . Additional features include six 16-bit general-purpose timers, two basic timers, two watchdog timers, a 7-channel DMA controller, a real-time clock (RTC) with sub-second accuracy, and up to 20 capacitive sensing channels for touch-key interfaces . The device also offers 73 I/O pins that are 5V-tolerant, enhancing interface flexibility with mixed-voltage systems .
