Product details
Overview
STM32L083VZT6TR from STMicroelectronics is an ultra-low-power 32-bit Arm® Cortex®-M0+ microcontroller with 192 KB Flash, 20 KB SRAM, and 6 KB EEPROM, integrated LCD driver, USB 2.0 (crystal-less), dual 12-bit DACs, and 12-bit ADC (1.14 Msps). It operates from 1.65–3.6 V across –40 to +125 °C and targets battery-powered industrial sensors and portable medical devices requiring long runtime and on-chip analog signal conditioning.
For engineers reviewing the STM32L083VZT6TR datasheet, STM32L083VZT6TR pinout, STM32L083VZT6TR application, or STM32L083VZT6TR equivalent, key selection criteria include its 0.86 µA Stop mode + RTC + 20-KB RAM retention, hardware AES-128 encryption, 24-channel capacitive touch sensing, and crystal-less USB support for compact, secure, low-power embedded systems.
Technical Context
The STM32L083VZT6TR implements a single-core Arm Cortex-M0+ with MPU, running at up to 32 MHz using multiple clock sources: HSI16 (16 MHz ±1%), HSI48 (48 MHz, self-calibrated for USB), LSE (32 kHz for RTC), and MSI (65 kHz–4.2 MHz). Its interconnect matrix routes peripherals-including dual DACs, 12-bit ADC, USB, and LCD-to memory and CPU without bus contention.
Low-power operation is enforced via five modes: Run (93 µA/MHz), Sleep, Low-power Run/Sleep, Stop (0.43 µA), and Standby (0.29 µA), each with configurable wakeup sources (e.g., 16 wakeup lines in Stop, 3 pins in Standby) and selective peripheral retention. The embedded voltage regulator supports dynamic voltage scaling to match performance to supply conditions.

FAQ
What is the maximum operating frequency and core type of the STM32L083VZT6TR?
The STM32L083VZT6TR uses an Arm Cortex-M0+ core with a maximum CPU frequency of 32 MHz. It achieves 0.95 DMIPS/MHz and includes a Memory Protection Unit (MPU) for enhanced software reliability. Frequency scaling is supported via dynamic voltage scaling to optimize power vs. performance across operating modes.
Does the STM32L083VZT6TR support crystal-less USB operation?
Yes-the device integrates a factory-trimmed 48 MHz HSI48 RC oscillator with self-calibration against USB SOF packets, enabling full-speed (12 Mbps) crystal-less USB 2.0 operation. This eliminates the need for an external 48 MHz crystal, reducing BOM cost and PCB footprint in portable and space-constrained designs.
How much EEPROM is available, and is it protected against unintended writes?
The STM32L083VZT6TR includes 6 KB of data EEPROM with built-in ECC for error correction and sector-level write protection. Each EEPROM sector can be independently locked against accidental program/erase operations via option bytes, ensuring data integrity in field-deployed devices subject to electrical noise or firmware bugs.
What LCD segment drive capability does the STM32L083VZT6TR provide?
The integrated LCD controller supports up to 4×52 or 8×48 segments, with programmable contrast adjustment, blinking mode, and on-board step-up converter for VLCD generation. It operates across the full –40 to +125 °C range and supports static, 2-, 3-, or 4-mux displays-ideal for battery-powered instrumentation and industrial HMIs without external LCD drivers.
