概述

Description

STM32L100R8T6A is an ultra-low-power MCU from STMicroelectronics, in the STM32L1 family and built around an ARM Cortex-M3 core. It’s designed for battery-powered and compact embedded apps.
Key points:
- Core and speed: ARM Cortex-M3, up to about 32 MHz.
- Memory: embedded Flash and RAM; exact sizes are variant-specific.
- Voltage/power: operates from 1.65 V to 3.6 V; supports multiple low-power modes (sleep/stop/standby) with very low current in standby.
- Peripherals: diverse set including timers, ADC (and sometimes DAC), cryptographic/CRC units, and common serial interfaces (USART/UART, I2C, SPI); USB FS is available on select devices; may include a basic LCD controller on some variants.
- Package: available in small, common packages (e.g., 48–64 pins) suitable for compact boards.
- Development: supported by ST’s tools (STCubeMX/HAL) and standard IDEs (Keil, IAR, GCC) with ST-LINK.
For exact memory sizes, peripheral list, and electrical specs, consult the official STM32L100R8T6A datasheet and reference manual.

Equivalent

There isn’t an exact one-to-one equivalent for STM32L100R8T6A. To find replacements, use ST’s Product Selector and Cross-Reference: filter by Cortex-M0+, memory, peripherals, package and voltage, then identify pin-compatible options in the STM32L0/L1 families with similar specs. Always verify package, flash/RAM size, peripherals, and voltage before swapping. If needed, consult ST support or a distributor’s cross-reference tool.
