The 64 KB SRAM supports moderate data buffering; if your application needs larger frame buffers or extensive lookup tables, you will want to budget the RAM against your task list early in the design phase. ## 100-ball BGA — footprint and rework considerations Housed in a 100-LFBGA (Low-profile Fine-pitch Ball Grid Array), this part is surface-mount only. The BGA package saves board area compared to an LQFP but requires X-ray inspection for solder-joint verification and a rework station with hot-air profile control. The 80 I/O count gives plenty of GPIO for parallel displays, external memory interfaces, or sensor arrays. STMicroelectronics lists the STM32F105VBH6 as Active.","metaTitle":"STM32F105VBH6 STM32F1 MCU, ARM Cortex-M3, 72 MHz","metaDescription":"STM32F105VBH6 32-bit ARM Cortex-M3 MCU, 72 MHz, 128 KB Flash, 64K x 8 SRAM, USB OTG, CAN, industrial temp -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"STM32F1","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"72MHz","Series":"STM32F1","Package":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, POR, PWM, Voltage Detect, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"80","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LFBGA","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F105","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.5000","priceTiers":[{"qty":1,"price":"$8.50000","currency":"USD"},{"qty":10,"price":"$7.67800","currency":"USD"},{"qty":25,"price":"$7.32120","currency":"USD"},{"qty":184,"price":"$6.35701","currency":"USD"},{"qty":368,"price":"$6.07130","currency":"USD"},{"qty":552,"price":"$5.53562","currency":"USD"},{"qty":1104,"price":"$4.82133","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/813271393bd0544f247ae965ea1bf2b0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F105VBH6/alternatives.json"},"ai":{"faq":[{"question":"What are the alternatives to STM32F105VBH6?","answer":"A functional peer within the STM32 portfolio is the STM32L151CBU6A, also an ARM Cortex-M3 but clocked at 32 MHz (vs 72 MHz) and with lower power draw. The STM32L151CBU6A has fewer I/O (37 vs 80) and a different peripheral set (no USB OTG, no CAN). It is not a pin-compatible drop-in — the package, pinout, and memory map differ — but it serves as a lower-power, lower-speed alternative for applications that do not need the full 72 MHz throughput or the USB OTG/CAN interfaces."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F105VBH6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F105VBH6 when reusing this data.
