Overview
STM32L152VEY6TR from STMicroelectronics is an ultra-low-power 32-bit Arm® Cortex®-M3 microcontroller with 512 KB Flash, 80 KB SRAM, 16 KB EEPROM, integrated LCD controller, USB 2.0 interface, and dual 12-bit ADC/DAC. It operates from 1.65 V to 3.6 V across -40 °C to +105 °C and delivers 195 µA/MHz in Run mode and 560 nA in Stop mode - enabling battery-powered medical sensors and portable industrial HMI displays.
For engineers reviewing the STM32L152VEY6TR datasheet, STM32L152VEY6TR pinout, STM32L152VEY6TR application, or STM32L152VEY6TR equivalent, key selection criteria include ultra-low-power mode current (560 nA Stop), LCD segment drive capability (8×40), USB 2.0 support with internal 48 MHz PLL, 102 I/Os (5V tolerant), and ECC-protected memory architecture.
Technical Context
The device implements dynamic voltage scaling and multiple low-power modes (Stop, Standby, Low-power Run) with sub-µA retention and <8 µs wakeup. Its Cortex-M3 core runs up to 32 MHz with MPU, supporting RWW Flash operation via dual-bank architecture.
Analog subsystem includes two rail-to-rail op-amps, two ultra-low-power comparators with window mode and wake-up capability, a temperature sensor, and VREFINT reference - all functional down to 1.8 V supply. The LCD controller supports contrast adjustment, blinking, and step-up converter for direct segment driving.

FAQ
What is the maximum operating frequency and corresponding power consumption in Run mode?
The STM32L152VEY6TR runs at up to 32 MHz with 195 µA/MHz typical current draw when executing code from Flash. At full speed, total active current is approximately 6.24 mA - verified under 3.3 V, 25 °C conditions with all peripherals disabled except core and SysTick.
Does this MCU support USB device functionality without external components?
Yes - the STM32L152VEY6TR integrates a full-speed USB 2.0 transceiver with internal 48 MHz PLL clock generation. Only standard USB termination resistors (1.5 kΩ pull-up on D+, 15 kΩ pull-down on D−) and ESD protection diodes are required for compliant device operation.
How many I/O pins are 5V tolerant, and what is their absolute maximum rating?
102 of the 116 I/Os are 5V tolerant. Their absolute maximum input voltage is 5.5 V regardless of VDD level, enabling safe interfacing with 5V logic systems while powered from 1.8 V or 3.3 V supplies - confirmed in Section 6.3.13 of DS10002 Rev 10.
Is the 16 KB EEPROM truly erasable at byte-level, and what is its endurance?
Yes - the 16 KB EEPROM supports byte, half-word, and word programming with 100,000 write/erase cycles minimum and 40-year data retention at 55 °C, as specified in Table 36 of the datasheet. ECC ensures bit-error recovery during read operations.
