Product details

Overview

STM32L073Z-EVAL from STMicroelectronics is an evaluation board for the STM32L073Z2 ultra-low-power Arm® Cortex®-M0+ MCU, featuring 192 KB Flash, 20 KB SRAM, 6 KB EEPROM, integrated LCD driver, USB 2.0 (crystal-less), and dual 12-bit DACs. It supports development of battery-powered IoT sensors, portable medical devices, and smart metering systems with real-time clock, capacitive touch, and ultra-low-power operation down to 0.29 µA in Standby mode.

For engineers reviewing the STM32L073Z-EVAL datasheet, STM32L073Z-EVAL pinout, STM32L073Z-EVAL application, or STM32L073Z-EVAL equivalent, this page provides verified hardware configuration details, on-board peripherals (USB, LCD, ADC/DAC, touch sensing), debug interface (SWD), power measurement points, and compatibility with STM32Cube ecosystem tools - critical for rapid prototyping and low-power firmware validation.

Technical Context

The STM32L073Z-EVAL implements a full-featured reference platform for the STM32L073Z2 MCU in UFBGA100 package, with direct access to all 84 fast I/Os (78 5V-tolerant), dedicated LCD segment drivers (up to 4×52), and on-board step-up converter for LCD bias. It integrates USB micro-B connector with battery charging detection, external crystal oscillators (1–25 MHz HSE + 32 kHz LSE), and calibrated internal RC sources (HSI16, HSI48, MSI).

Hardware design includes SWD debugging via ST-LINK/V2-1, user LEDs/buttons, potentiometer for analog input, temperature sensor, and jumper-configurable power domains (VDD, VDDA, VLCD) enabling precise current profiling across Run, Stop, and Standby modes - essential for validating ultra-low-power firmware behavior per DS10685 Rev 7 specifications.

FAQ

Does STM32L073Z-EVAL include an onboard debugger?

Yes - it integrates ST-LINK/V2-1, a certified CMSIS-DAP-compliant debug probe supporting SWD interface, real-time programming, and full-speed tracing. No external debugger is required for flashing or debugging the STM32L073Z2 MCU, and it exposes virtual COM port and mass storage device functionality via USB.

What LCD configurations does the board support out-of-the-box?

The board supports 4×52 segment LCDs using the on-chip controller, with on-board step-up converter generating VLCD (adjustable 2.3–3.3 V). Contrast is software-tunable via DAC output, and blinking mode is configurable per segment group - validated with standard STN glass modules used in metering and portable instrumentation.

Can STM32L073Z-EVAL measure current consumption in different low-power modes?

Yes - it features solder-jumper-selectable power paths for VDD, VDDA, and VLCD, with test points enabling direct multimeter or current probe measurement. The board's schematic allows isolation of MCU core, analog domain, and LCD supply - enabling accurate validation of datasheet current specs (e.g., 0.29 µA Standby, 0.86 µA Stop+RTC+RAM retention).

Is USB battery charging detection functional without external components?

Yes - the STM32L073Z2 MCU implements USB BC 1.2-compliant battery charging detection in hardware. The board routes USB D+/D− directly to the MCU and includes necessary pull-up/pull-down resistors and VBUS sensing, allowing immediate use of USB enumeration and charger type identification (SDP/CDP/DCP) in firmware without external ICs.
