The connectivity set includes CANbus for industrial fieldbus, USB OTG for host/device switching, and an EBI/EMI bus for glueless connection to external SRAM, NOR Flash, or LCD controllers. This is a standard-production STM32L4R series device, widely stocked across the distribution channel. For dual-sourcing or supply resilience, note that the STM32L151CBU6A is a different series (STM32L1, Cortex-M3 at 32 MHz) and is not a pin-compatible or functional substitute — the L4R5's 120 MHz core, 1 MB Flash, and 640 KB SRAM are in a higher performance tier. No direct second-source alternate exists; the STM32L4R5 is a single-sourced ST part.","metaTitle":"STM32L4R5QGI6 STM32L4R MCU, 120 MHz Cortex-M4, 1 MB Flash","metaDescription":"STMicroelectronics STM32L4R5QGI6 32-bit ARM Cortex-M4 MCU, 120 MHz, 1 MB Flash, 640 KB SRAM, 110 I/O, 132-UFBGA, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"STM32L4R","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"120MHz","Series":"STM32L4R","Package":"Tray","RAM Size":"640K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, I²C, IrDA, LINbus, MMC/SD, SAI, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"110","Core Processor":"ARM® Cortex®-M4","Package / Case":"132-UFBGA","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L4R5","Program Memory Size":"1MB (1M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"132-UFBGA (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$14.3300","priceTiers":[{"qty":1,"price":"$14.33000","currency":"USD"},{"qty":10,"price":"$13.17500","currency":"USD"},{"qty":25,"price":"$12.62840","currency":"USD"},{"qty":80,"price":"$11.12663","currency":"USD"},{"qty":416,"price":"$10.58058","currency":"USD"},{"qty":832,"price":"$9.89797","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3911b6923e911f78d930b1bab40f9562.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L4R5QGI6/alternatives.json"},"ai":{"faq":[{"question":"What is the equivalent of STM32L4R5QGI6?","answer":"There is no direct pin-compatible second-source alternate.
