Product details
Overview
STM32L063C8U6 from STMicroelectronics is an ultra-low-power 32-bit Arm® Cortex®-M0+ microcontroller featuring 64 KB Flash, 8 KB SRAM, 2 KB EEPROM with ECC, integrated LCD driver (8×28 segments), USB 2.0 crystal-less interface, and hardware AES-128 encryption. It operates from 1.65 V to 3.6 V across –40 °C to +125 °C and delivers 0.27 µA standby current with 2 wakeup pins - ideal for battery-powered smart meters and portable medical sensors.
For engineers reviewing the STM32L063C8U6 datasheet, STM32L063C8U6 pinout, STM32L063C8U6 application, or STM32L063C8U6 equivalent, key selection criteria include ultra-low-power mode timing (3.5 µs RAM wakeup), 12-bit ADC (1.14 Msps, 16-channel), DAC output buffer support down to 1.8 V, and USB LPM with battery charging detection - all validated in DS10090 Rev 8.
Technical Context
The STM32L063C8U6 integrates a Cortex-M0+ core with MPU, running at up to 32 MHz (0.95 DMIPS/MHz), supported by multiple clock sources: HSI16 (±1%), LSE (32 kHz RTC), and self-calibrating 48 MHz HSI48 for USB. Its interconnect matrix enables concurrent peripheral access without bus contention.
Low-power architecture includes five operational modes (Run, Sleep, Low-power Run/Sleep, Stop, Standby), with dedicated voltage regulators, BOR thresholds (5 selectable), and PVD - enabling precise power-state transitions in energy-constrained edge nodes.

FAQ
What is the maximum operating frequency and core type of the STM32L063C8U6?
The STM32L063C8U6 features an Arm Cortex-M0+ core rated for up to 32 MHz operation, delivering 0.95 DMIPS/MHz performance. It includes a Memory Protection Unit (MPU) and supports dynamic voltage scaling to optimize power versus performance. This frequency is achievable across the full 1.65–3.6 V supply range and –40 °C to +125 °C temperature span, as confirmed in DS10090 Rev 8 Section 3.3.
Does the STM32L063C8U6 support USB without an external crystal?
Yes - the STM32L063C8U6 integrates a crystal-less USB 2.0 interface using its self-calibrating 48 MHz HSI48 oscillator, eliminating the need for an external 48 MHz crystal or oscillator. It also supports battery charging detection (BCD) and Link Power Management (LPM), as specified in Section 3.20.5 of DS10090 Rev 8.
How many I/O pins are 5V tolerant, and what is the total I/O count?
The STM32L063C8U6 provides up to 51 fast I/Os, of which 45 are 5V tolerant. This tolerance applies to specific pins (PA0–PA15, PB0–PB15, PC0–PC15, PD0–PD12, PH0–PH1) under defined voltage and current limits per Section 6.3.13 of DS10090 Rev 8 - enabling safe interfacing with legacy 5V peripherals without level shifters.
What LCD capabilities does the STM32L063C8U6 offer, and how is contrast controlled?
The STM32L063C8U6 integrates an LCD controller supporting up to 8 commons and 28 segments (224 total), with on-chip step-up converter and programmable contrast adjustment via internal voltage divider registers. Contrast is adjusted digitally through the LCD_CR register's CC bits, allowing fine-grained tuning without external potentiometers or resistor networks - detailed in Section 3.11 of DS10090 Rev 8.
