概述

Description

STM32L011F3U3TR is a low-power, 32‑bit microcontroller from ST’s STM32L0 family. It targets energy‑constrained apps (battery, wearables, sensing) with an ARM Cortex‑M0+ core.
Key points:
- Core and speed: ARM Cortex‑M0+ up to about 32 MHz.
- Power: multiple ultra‑low‑power modes with fast wakeup; optimized for low current in run/stop/ standby.
- Voltage: wide VDD range (often 1.65–3.6 V).
- Memory: Flash up to tens of kilobytes; RAM a few kilobytes (variant dependent).
- Peripherals: 12‑bit ADC, comparators/OPAMP, timers, RTC, and common interfaces (I2C, SPI, USART).
- Debug/programming: SWD/JTAG compatible.
- Package: compact U3 package (tape and reel).
Note: exact Flash/RAM, I/O count, and peripheral set vary by exact revision. Consult the datasheet/product page for the precise specs of your part. If you want, I can pull the exact numbers for STM32L011F3U3TR.

Features

Key features of STM32L011F3U3TR (STM32L0 ultra‑low‑power line):
- CPU: 32-bit ARM Cortex‑M0+ core, up to 32 MHz.
- Power: ultra‑low‑power design with multiple run/stop/standby modes; very low wake‑up currents for battery‑powered apps.
- Memory: up to 16 KB Flash and up to 4 KB SRAM (typical for value devices in this family).
- Peripherals: 12‑bit ADC with analog features; multiple timers (including 16‑bit timers); DMA; standard serial comms: USART/UART, SPI, I2C.
- Real‑time/clock: RTC with LSE/low‑speed clock support.
- Security/ROM: built‑in bootloader, CRC engine, and read‑out protection options.
- I/O: multiple GPIOs with digital peripherals and basic PWM capabilities.
- Operating voltage/temperature: 1.65–3.6 V; operating temp range typically −40°C to 85°C.
- Packaging: compact, suitable for small-footprint designs.
Note: exact RAM/Flash counts and peripheral counts can vary by specific package/variant; verify against the datasheet for your exact device revision.
