Product details
Overview
STM32L152R6T6TR from STMicroelectronics is an ultra-low-power 32-bit ARM® Cortex®-M3 microcontroller featuring 128 KB Flash, 16 KB SRAM, 4 KB EEPROM with ECC, USB 2.0 interface, and 12-bit ADC (1 Msps, up to 24 channels) - deployed in battery-powered medical sensors and portable industrial data loggers requiring sub-1 µA standby current.
For engineers reviewing the STM32L152R6T6TR datasheet, STM32L152R6T6TR pinout, STM32L152R6T6TR application, or STM32L152R6T6TR equivalent, key selection criteria include verified ultra-low-power mode timing (0.3 µA Standby), integrated LCD driver (STM32L152xx only), USB 48 MHz PLL stability, and 73 I/Os with 5V tolerance - all confirmed for LQFP64 package operation.
Technical Context
The STM32L152R6T6TR implements dynamic voltage scaling across five low-power modes (Run, Sleep, Low-power Run, Stop, Standby), with hardware-accelerated ECC for Flash and EEPROM, and a dedicated LCD controller supporting up to 8×40 segments - exclusive to STM32L152 variants. Its clock system integrates six oscillators: HSE (1–24 MHz), LSE (32.768 kHz), HSI (16 MHz ±1%), LSI (37 kHz), MSI (65 kHz–4.2 MHz), and USB PLL (48 MHz).
It features dual 12-bit DACs with output buffers, two ultra-low-power comparators with window mode and wake-up capability, and a capacitive sensing controller supporting 20 channels for touchkey/rotary applications - all operable down to 1.8 V analog supply. The 7-channel DMA controller enables zero-CPU-load peripheral-to-memory transfers.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32L053R8T6 | Lower memory (64 KB Flash, 8 KB RAM), no LCD controller, single 12-bit DAC, no USB - uses Cortex-M0+ core. | Suitable for simpler sensor nodes without display or USB connectivity; lacks RTC calibration and EEPROM ECC. | Select when BOM cost reduction outweighs LCD/USB requirements and application complexity remains low. |
| STM32L432KCU6 | Cortex-M4F core, 256 KB Flash, 64 KB SRAM, no EEPROM, USB but no LCD driver, higher active current (80 µA/MHz). | Better for DSP-intensive tasks (e.g., audio processing); requires external display driver and lacks EEPROM-based parameter retention. | Choose when floating-point math or larger code footprint is required, and ultra-low standby (<1 µA) is not mandatory. |
Compared with STM32L152R6T6TR, STM32L053R8T6 trades LCD/USB/ECC for lower cost and smaller footprint, while STM32L432KCU6 upgrades compute capability at the expense of standby power and integrated peripherals - making STM32L152R6T6TR optimal for display-equipped, USB-enabled, long-life battery applications.

FAQ
What is the maximum operating temperature for STM32L152R6T6TR?
The STM32L152R6T6TR is qualified for industrial operation from -40°C to +105°C ambient temperature. This rating is validated per ST's production test flow and applies to all LQFP64 devices shipped under this part number. Thermal derating begins above 85°C for sustained 100% CPU load, but RTC and standby functions remain fully specified up to 105°C.
Does STM32L152R6T6TR support USB device mode only, or also host mode?
The STM32L152R6T6TR implements USB 2.0 Full-Speed device mode only, with an internal 48 MHz PLL and dedicated USB transceiver. It does not support USB host or OTG functionality. All USB endpoints (control, bulk, interrupt, isochronous) are supported in device mode, and the bootloader includes USB DFU class support for firmware updates.
How many I/O pins are 5V tolerant, and under what conditions?
73 I/O pins on the STM32L152R6T6TR are 5V tolerant when VDD is powered (1.65–3.6 V) and the pin is configured as input, output, or alternate function - excluding BOOT0 and JTAG/SWD pins. Tolerance is guaranteed per ST specification AN4229 and applies only when VDD ≥ 2.0 V; no external clamping diodes are required for 5V signal interfacing.
Is the LCD controller present in STM32L152R6T6TR, and what segment drive capability does it offer?
Yes, the STM32L152R6T6TR includes a full-featured LCD controller supporting up to 8 commons and 40 segments (8×40), with programmable bias, contrast adjustment, blinking mode, and integrated step-up converter. This feature is exclusive to STM32L152 variants (not present in STM32L151) and operates independently of main CPU activity in low-power modes.
