STM32L100RCT6TR

STM32L100RCT6TR is a 64-pin ultra-low-power microcontroller from STMicroelectronics, part of the STM32L1 family. It uses a 32‑bit ARM Cortex‑M3 core, runs up to 32 MHz, and combines on‑chip flash and RAM with a broad set of peripherals. Peripherals typically include multiple timers, ADC and DAC, GPIOs, and common serial interfaces (USART/UART, SPI, I2C); some variants may include USB and/or CAN. It supports several low‑power modes (sleep/stop) and operates from a wide voltage range (about 1.65–3.6 V) for battery-powered applications. The suffix RCT6 denotes a 64‑pin LQFP package, and TR indicates tape‑and‑reel packaging. Typical uses include wearable devices, wireless sensor nodes, portable instrumentation, and IoT devices. For exact memory sizes, peripheral sets, electrical characteristics, and power modes, consult the STM32L100RCT6TR datasheet and reference manual on ST’s website.

Do you want pin-for-pin/functional equivalents within STM32, or cross-vendor parts (NXP, Microchip, etc.)? Please specify:
- package (likely LQFP48, but confirm)
- required flash/SRAM sizes
- key peripherals (USB, ADC, RTC, DMA, timers)
- operating voltage and clock features
With those, I can provide exact cross‑references.
