概述

Description

STM32L073RZT6TR is a low-power MCU from STMicroelectronics’ STM32L0 family. It uses a 32-bit ARM Cortex‑M0+ core, running up to about 32 MHz, designed for battery-powered and energy-efficient apps.
Key features:
- Memory: up to 128 KB Flash, ~20 KB RAM
- Peripherals: USB 2.0 Full‑Speed device, USART/UART, SPI, I2C/I2S, 12‑bit ADC, timers, DMA, and an LCD controller for small displays
- Analog/digital: multiple GPIOs with flexible alternate functions
- Power: operate 1.65–3.6 V with low‑power modes (Sleep, Stop, Standby) and RTC
- Package: suffixes indicate a 64‑pin package (RZT6) and Tape & Reel (TR) packaging
- Applications: wearable devices, battery-powered sensors, compact IoT nodes
- Development: supported by STM32CubeMX, HAL/LL drivers, and common IDEs (Keil, IAR, SW4STM32)
This makes it a good fit for cost- and power-sensitive embedded projects requiring USB and LCD capability.

Features

Key features of STM32L073RZT6TR:
- Core: 32-bit ARM Cortex-M0+ up to 32 MHz
- Ultra-low power: multiple sleep modes (Run, Sleep, Stop, Standby) with very low current
- Memory: up to 128 KB Flash and up to about 20 KB RAM (package dependent)
- USB: USB 2.0 Full-Speed device interface
- LCD: integrated LCD controller for multiplexed segment displays
- Clocks: HSE/HSI, LSE; PLL to generate 48 MHz for USB
- Peripherals: I2C, SPI, USART/UART (multiple instances); 12-bit ADC; multiple timers; RTC with calendar
- DMA and CRC: DMA controller and hardware CRC
- Watchdogs and security: IWDG/WWDG; BOR and option bytes with readout protection
- Power/voltage: operating 1.65–3.6 V; wide temperature range (-40 to 85°C)
- Packaging: available in compact packages (RZT variants) for dense designs
Note: exact memory sizes and package options vary by specific variant and package. Refer to the datasheet for definitive figures.

Package

LQFP-64 package (64-pin, package code RZ). The TR suffix indicates Tape-and-Reel packaging.

Pinout

- Industrial sensing, metering, and data loggers
- Compact consumer electronics requiring low power, USB, and LCD support

Equivalent

There isn’t an exact cross‑vendor drop‑in for STM32L073RZT6TR. Within ST, the closest pin‑compatible 48‑pin L0 MCU is STM32L072RZT6 (similar core, memory and peripherals). For non‑ST options, compare 32‑bit ARM MCUs with similar flash/RAM and peripherals (e.g., TI MSP432, NXP LPC55S6x). They won’t be pin‑ or software‑compatible. Use ST’s product selector to find exact equivalents.
