The 640 KB SRAM is notably generous for a Cortex-M4 in this power tier; it reduces the need for external memory in designs that buffer camera frames, audio streams, or large telemetry logs. The 1 MB Flash supports multi-image bootloaders and field-upgradeable firmware without squeezing code into tight sectors. ## 132-UFBGA 7x7 mm — footprint decisions for the layout engineer The STM32L4R5QGI6TR comes in a 132-ball Ultra-Fine-Pitch BGA (UFBGA) measuring 7x7 mm. This is a dense, fine-pitch package that requires careful PCB layout: via-in-pad or microvia fanout is typical, and the exposed center pad must be stitched to a solid ground plane with enough thermal vias to keep the junction below the 85°C industrial limit under continuous load. Surface-mount assembly with a 132-UFBGA means the board house needs a solder-paste stencil matched to the 0.5 mm or finer ball pitch. The base product number is STM32L4R5, part of the STM32L4 series which shares a common pinout across density options. If a future design requires more Flash or RAM, pin-compatible siblings in the same family are available without a PCB spin.","metaTitle":"STM32L4R5QGI6TR ARM Cortex-M4 MCU, 120MHz, 1MB Flash","metaDescription":"STMicroelectronics STM32L4R5QGI6TR 32-bit ARM Cortex-M4 MCU at 120MHz with 1MB Flash, 640KB SRAM, 110 I/O, 132-UFBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"120MHz","Series":"STM32L4","Package":"Tape & Reel (TR)","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":"$11.2332","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/88138dadbb0c596c6bce82bbbcce3d64.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the equivalents or substitutes for STM32L4R5QGI6TR?","answer":"Pin-compatible alternatives exist within the STM32L4R5 series and the broader STM32L4 family, sharing the same base footprint and peripheral set.
