The MCU integrates a broad set of peripherals: a 12-bit ADC with 16 channels, two 12-bit DACs, multiple timers with PWM, and a flexible memory controller supporting QSPI and SAI. This makes it suitable for industrial fieldbus nodes, audio processing, and IoT edge devices that need to talk to sensors, displays, and wired networks from a single chip. For designs that need the same core in a larger package for easier prototyping, the STM32F423 line includes LQFP variants with identical peripheral sets.","metaTitle":"STM32F423MHY6TR STM32F4 ARM Cortex-M4 MCU, 100MHz","metaDescription":"STMicroelectronics STM32F423MHY6TR 32-bit ARM Cortex-M4 MCU, 100MHz core, 1.5MB Flash, 320KB SRAM, 81-WLCSP package, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"100MHz","Series":"STM32F4","Package":"Tape & Reel (TR)","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, I²C, IrDA, LINbus, MMC/SD, QSPI, SAI, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"60","Core Processor":"ARM® Cortex®-M4","Package / Case":"81-UFBGA, WLCSP","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":"81-WLCSP (4.04x3.95)","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.5937","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a8eec206e25d15b1357ecef3f9cdd4fe.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F423MHY6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STM32F423MHY6TR?","answer":"Within the STM32F423 family, the same MCU core is available in different package options (LQFP, UFBGA) with identical peripheral sets.
