The 100-UFBGA package (7x7 mm) keeps the footprint small for dense PCB layouts, though the BGA requires controlled reflow and X-ray inspection. ## Where the 16-bit ADC matters The three 16-bit sigma-delta ADCs are the headline feature for designs that need better than 12-bit resolution on multiple channels — think weigh scales, pressure transducers, or current-sense in motor drives where the extra bits save an external ADC and its SPI interface. The three 12-bit DACs can simultaneously drive analog outputs for setpoint control or waveform generation. The 72 MHz Cortex-M4 handles the math for PID loops, digital filters, or FFT analysis on the acquired data without a separate DSP. The supply range of 2.0 V to 3.6 V covers both 3.3 V and battery-backed 2.5 V rails, though the internal oscillator and Flash read path need a clean 3.3 V for full 72 MHz operation. The 100-UFBGA package with 0.5 mm pitch demands careful PCB land pattern design and a stencil aperture that matches the 7x7 mm body — not a hand-solder part, but fine for automated assembly lines. For new designs this removes the obsolescence risk that haunts older STM32F1 or F2 parts. The base product number STM32F373 covers a range of Flash and package options, so if a future BOM needs more memory or a different footprint, the migration stays within the same family and peripheral set.","metaTitle":"STM32F373VCH6 ARM Cortex-M4 MCU, 72MHz, 256KB Flash","metaDescription":"STMicroelectronics STM32F373VCH6 32-bit MCU with ARM Cortex-M4 core, 72MHz speed, 256KB Flash, 32K x 8 RAM, 3x 16-bit ADC, 3x 12-bit DAC, CANbus, USB","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":"STM32F3","Package":"Tray","RAM Size":"32K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"84","Core Processor":"ARM® Cortex®-M4","Package / Case":"100-UFBGA","Product Status":"Active","Data Converters":"A/D 1x12b, 3x16b; D/A 3x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F373","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-UFBGA (7x7)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.5100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c0be2342f78564e007e57aa9d0615805.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F373VCH6/alternatives.json"},"ai":{"faq":[{"question":"Can STM32F373VCH6 replace STM32F373VBT6?","answer":"The STM32F373VBT6 is a different package variant (LQFP) with the same core and memory. The VCH6 uses a 100-UFBGA package, so a direct drop-in replacement is not possible without a PCB layout change. The electrical and firmware compatibility is otherwise identical within the STM32F373 family."},{"question":"Are there alternatives to STM32F373VCH6?","answer":"Within the STM32F3 series, the STM32F373VCT6 offers the same core and peripherals in an LQFP-100 package for designs that prefer a QFP over BGA. For higher performance, the STM32F3x4 or STM32F3x8 families add more Flash or higher clock speeds, but the 16-bit ADC feature is specific to the STM32F373 line."},{"question":"Is STM32F373VCH6 compatible with STM32F3 Discovery board?","answer":"The STM32F3 Discovery board (STM32F3DISCOVERY) uses an STM32F303VCT6 MCU in an LQFP-100 package, not the BGA-packaged STM32F373VCH6.
