The 64-LQFP package provides 52 I/O. ## Supply and temperature — single-cell Li-ion friendly Brown-out detect and reset are on-chip, so an external supervisor isn't required for basic power-fail handling. ## Peripheral mix — Quad SPI, USB, and multiple serial buses DMA is available across all major peripherals, so the CPU isn't stalled moving data from the ADC or serial buffers. No USB OTG is listed in the connectivity set — the USB peripheral is device-only.","metaTitle":"ST STM32L412R8T6 ARM Cortex-M4 MCU, 80 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32L412R8T6 32-bit MCU: ARM Cortex-M4 at 80 MHz, 64 KB Flash, 40 KB SRAM, 52 I/O, -40°C to 85°C, 1.71-3.6 V.","metaKeywords":null},"attributes":{"series":"STM32L4","packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"80MHz","Series":"STM32L4","Package":"Tray","RAM Size":"40K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, PWM, WDT","Connectivity":"I²C, Infrared, IrDA, LINbus, Quad SPI, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"52","Core Processor":"ARM® Cortex®-M4","Package / Case":"64-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L412","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.7300","priceTiers":[{"qty":1,"price":"$5.73000","currency":"USD"},{"qty":10,"price":"$5.14600","currency":"USD"},{"qty":25,"price":"$4.86480","currency":"USD"},{"qty":80,"price":"$4.21600","currency":"USD"},{"qty":230,"price":"$3.99978","currency":"USD"},{"qty":440,"price":"$3.58900","currency":"USD"},{"qty":960,"price":"$3.02688","currency":"USD"},{"qty":2880,"price":"$2.94825","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/59cb278680a203c58c9194c1c9266f14.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L412R8T6/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32L412R8T6 and STM32L432KC?","answer":"The STM32L432KC is a different density variant in the STM32L4 series with a different Flash/RAM configuration and package. The STM32L412R8T6 offers 64 KB Flash and 40 KB SRAM in a 64-LQFP, while the STM32L432KC typically has a smaller Flash and a different pin count. For exact parametric differences, consult the respective datasheets — they share the same Cortex-M4 core and ultra-low-power architecture but differ in memory and I/O count."},{"question":"What package does the STM32L412R8T6 use?","answer":"The STM32L412R8T6 is supplied in a 64-LQFP package (10x10 mm body) with a 0.5 mm pitch.
