At the 3.3 V end, the 100 MHz PLL draws the full dynamic current — plan the 3.3 V rail for at least 50 mA headroom above the MCU's own consumption when all peripherals are clocked. ST lists the STM32F423VHT6 as Active product status. The ROHS3 compliance is current. For production planning, the part is available through franchised distribution and the independent channel; any allocation risk today is driven by the overall STM32 supply picture, not by an imminent end-of-life. ## Connectivity and analog — what the 100-LQFP footprint buys you The peripheral set includes CANbus, USB OTG, QSPI, SAI audio, and an EBI/EMI interface for external memory or FPGA glue. The internal oscillator is rated for operation, but for CAN or USB with tight bit-timing, an external crystal is the safer choice — the internal RC drifts enough across temperature to risk frame errors at 1 Mbps.","metaTitle":"STM32F423VHT6 STM32F4 MCU, ARM Cortex-M4, 100MHz","metaDescription":"STMicroelectronics STM32F423VHT6 32-bit ARM Cortex-M4 MCU, 100MHz, 1.5MB Flash, 320KB RAM, 100-LQFP.","metaKeywords":null},"attributes":{"series":"STM32F4","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"100MHz","Series":"STM32F4","Package":"Tray","RAM Size":"320K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I2S, LCD, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, I2C, IrDA, LINbus, MMC/SD, QSPI, SAI, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"81","Core Processor":"ARM® Cortex®-M4","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F423","Program Memory Size":"1.5MB (1.5M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$14.5200","priceTiers":[{"qty":1,"price":"$14.52000","currency":"USD"},{"qty":10,"price":"$13.34800","currency":"USD"},{"qty":25,"price":"$12.79440","currency":"USD"},{"qty":80,"price":"$11.27288","currency":"USD"},{"qty":230,"price":"$10.71961","currency":"USD"},{"qty":540,"price":"$10.02802","currency":"USD"},{"qty":1080,"price":"$9.19811","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a8eec206e25d15b1357ecef3f9cdd4fe.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F423VHT6/alternatives.json"},"ai":{"faq":[{"question":"Can STM32F423VHT6 replace STM32F423VGT6?","answer":"The STM32F423VHT6 and STM32F423VGT6 share the same base part number, package (100-LQFP), and die. The difference is Flash density: the VHT6 carries 1.5 MB, while the VGT6 carries 1 MB. If your firmware fits within 1 MB, the VGT6 is a drop-in replacement at a lower BOM cost. If you need the full 1.5 MB, the VHT6 is the correct order code. No pinout or peripheral changes between them."},{"question":"Is STM32F423VHT6 compatible with STM32CubeIDE?","answer":"Yes. The STM32F423VHT6 is an STM32F4-series device.
