Ten 12-bit ADC channels and two 12-bit DAC channels cover analog sensing and control outputs. ## Industrial temperature grade and compact 48-UFQFN package The 48-UFQFN exposed-pad package measures 7x7 mm. With 36 I/O available, the pin count is modest — suited for designs that need a rich peripheral set (CAN, USB OTG, multiple UARTs and SPI) in a small footprint.","metaTitle":"STM32F423CHU6 STM32F4 ARM Cortex-M4 MCU, 100 MHz","metaDescription":"STMicroelectronics STM32F423CHU6 32-bit ARM Cortex-M4 MCU, 100 MHz core, 1.5 MB Flash, 320 KB SRAM, industrial temp -40°C to 85°C, 48-UFQFN.","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":"Tray","RAM Size":"320K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, MMC/SD, SAI, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"36","Core Processor":"ARM® Cortex®-M4","Package / Case":"48-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 10x12b; 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":"48-UFQFPN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$15.4600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a8eec206e25d15b1357ecef3f9cdd4fe.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F423CHU6/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32F423 and STM32F413?","answer":"The STM32F423 is a lower-pin-count, smaller-package variant (48-UFQFN vs typically larger packages on the STM32F413). Both share the same 100 MHz Cortex-M4 core and 1.5 MB Flash, but the STM32F423CHU6 offers 36 I/O and a reduced peripheral set compared to the higher-pin-count STM32F413 parts.

The STM32F413 parts use different packages and are not pin-compatible. For a direct drop-in, check the STM32F423xH variants with the same 48-UFQFN package — they differ only in Flash and SRAM sizes."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F423CHU6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F423CHU6 when reusing this data.
