The 144-LFBGA (10x10 mm) package brings 112 I/O lines, including multiple SPI, I2C, UART/USART, and a full-speed USB 2.0 interface. On-chip peripherals include DMA, motor-control PWM, a temperature sensor, and a watchdog timer — the usual STM32F103 complement, but with the I/O count and memory headroom to handle more complex control loops. ## CANbus connectivity confirmed The connectivity list includes CANbus, so this MCU can serve as a CAN node in automotive aftermarket, industrial automation, or building-management systems. The bxCAN peripheral supports 2.0 A and 2.0 B active, with three transmit mailboxes and two receive FIFOs — enough for a typical gateway or sensor hub without an external CAN controller. STMicroelectronics lists this part as Active. ## 144-LFBGA footprint and rework notes If your rework lab handles BGA regularly, this is routine; if not, budget for a stencil design with 0.4 mm aperture and a nitrogen-assisted reflow to minimize solder ball bridging.","metaTitle":"STM32F103ZGH7 STM32F1 ARM Cortex-M3 MCU, 72 MHz, 1 MB Flash","metaDescription":"STM32F103ZGH7 32-bit ARM Cortex-M3 MCU, 72 MHz, 1 MB Flash, 96 KB SRAM, 112 I/O, CAN, -40 to 105°C, 144-LFBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"72MHz","Series":"STM32F1","Package":"Tray","RAM Size":"96K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, Motor Control PWM, PDR, POR, PVD, PWM, Temp Sensor, WDT","Connectivity":"CANbus, I2C, IrDA, LINbus, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"112","Core Processor":"ARM® Cortex®-M3","Package / Case":"144-LFBGA","Product Status":"Active","Data Converters":"A/D 21x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F103","Program Memory Size":"1MB (1M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"144-LFBGA (10x10)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.7984","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1e0a2899638e8adeb34943c703bd9a9b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F103ZGH7/alternatives.json"},"ai":{"faq":[{"question":"Does STM32F103ZGH7 support CAN communication?","answer":"Yes, the STM32F103ZGH7 includes a CANbus interface (bxCAN peripheral) supporting CAN 2.0 A and 2.0 B.
