That RAM-to-Flash ratio is the standout feature: the part is clearly intended for designs that run code from external Flash or QSPI memory while using the internal RAM for frame buffers, large data arrays, or real-time audio processing. The 1.4 MB RAM is enough to hold a full VGA frame buffer at 16-bit color with room to spare for stack and heap. The peripheral set backs up that display-and-connectivity focus: the part includes a parallel LCD interface, camera interface, HDMI-CEC, SAI for audio, SPDIF, and USB OTG. The 49 I/Os in the 64-pin package mean most of these interfaces are available simultaneously, but you will need to check the pin-multiplexing table for your specific combination — the EBI/EMI bus and LCD share pins with some of the serial interfaces. ## Mixed-signal capability — 16-bit ADC and 12-bit DAC on board The data converter section includes a 16-channel, 16-bit analog-to-digital converter and a 3-channel, 12-bit digital-to-analog converter. The 16-bit ADC resolution is a step above the common 12-bit ADCs found on many MCUs, which matters for precision sensor acquisition — think load cells, thermocouple interfaces, or audio input stages where every bit of dynamic range counts. The three DAC channels can generate analog control voltages for external regulators, VCO tuning, or waveform synthesis without an external converter IC.","metaTitle":"STM32H7B0RBT6 ARM Cortex-M7 MCU, 280 MHz, 128 KB Flash","metaDescription":"STMicroelectronics STM32H7B0RBT6 32-bit ARM Cortex-M7 MCU at 280 MHz with 128 KB Flash, 1.4 MB RAM, 64-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"280MHz","Series":"STM32H7","Package":"Tray","RAM Size":"1.4M x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, LCD, POR, PWM, WDT","Connectivity":"Camera, CANbus, EBI/EMI, HDMI-CEC, I²C, IrDA, LINbus, MDIO, MMC/SD/SDIO, PSSI, SAI, SPDIF, SPI, SWPMI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"49","Core Processor":"ARM® Cortex®-M7","Package / Case":"64-LQFP","Product Status":"Active","Data Converters":"A/D 16x16b; D/A 3x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32H7B0","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.62V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.1151","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0fe28a8d41b921baedb236fa0aa207b5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is STM32H7B0RBT6 compatible with STM32H743?","answer":"The STM32H7B0RBT6 and STM32H743 share the same Cortex-M7 core and STM32H7 family architecture, but they are not pin-compatible. The STM32H7B0RBT6 comes in a 64-LQFP package with 49 I/Os, while the STM32H743 is typically offered in larger packages with more I/Os and a different peripheral set.
