The STM32L151UCY6DTR from STMicroelectronics is an ultra-low-power 32-bit ARM Cortex-M3 MCU. It features 256KB flash, 32KB SRAM, and runs at 32MHz. The 63-UFBGA WLCSP package measures just a few millimeters. With Cap Sense, DMA, and multiple low-power modes, it targets battery-powered portable devices.
- Ultra-compact WLCSP: Enables miniaturized product designs.
- 1.65V operation: Works directly with single alkaline or Li-ion cells.
- 256KB flash + 32KB SRAM: Ample memory for complex firmware.
- Rich peripherals (DMA, I2S, PWM): Flexible for various sensor interfaces.
Wearable Fitness Trackers
Ultra-small WLCSP package fits in wristbands. 1.65V operation works with coin cells. DMA transfers sensor data without CPU load.
Smart Watches
Cap Sense detects touch gestures on the display. 256KB flash stores watch faces. Low-power modes extend battery life to weeks.
Medical Patch Sensors
32MHz Cortex-M3 processes ECG signals. 32KB SRAM buffers real-time data. I2S interfaces with audio codecs for alerts.
IoT Sensor Nodes
Multiple PWM channels drive actuators. POR ensures clean startup from energy harvesting. WDT prevents firmware hangs.
Portable Glucose Meters
Cap Sense buttons are sealed against contamination. DMA moves ADC results to memory. 3.6V max allows direct battery connection.
Smart Cards
WLCSP package enables thin card designs. Low power consumption suits passive NFC harvesting. 256KB flash stores secure applets.
