The 1 MB Flash (1M x 8) and 192 KB SRAM (192K x 8) provide memory for a real-time OS, a TCP/IP stack, and a display buffer. With 82 I/O brought out to a 100-pin LQFP (100-LQFP, 14x14 mm body), this part fits on a four-layer board without blind vias. The peripheral set includes CANbus, EBI/EMI for external SRAM or NOR Flash, multiple I²C and SPI buses, and USB OTG — enough connectivity to serve as the main controller in an industrial PLC, a motor drive, or a human-machine interface panel. D/A 2x12b) are integrated on-chip, which saves the cost of an external analog front-end for multi-sensor acquisition or closed-loop analog outputs. The 168 MHz Cortex-M4 FPU enables single-cycle MAC operations. The ART Accelerator hides most flash wait-state penalties for sequential code. ## 1 MB Flash and 192 KB SRAM — sizing the firmware and data budget 1 MB of Flash (1M x 8) is the high-density tier in the STM32F4 family. It fits a full FreeRTOS or ThreadX kernel, a LwIP TCP/IP stack, a USB device stack, and a graphical library like LVGL with room left for application code. The 192 KB SRAM (192K x 8) is split across multiple blocks — 64 KB of CCM (core-coupled memory) runs at full 168 MHz without bus contention, ideal for critical interrupt handlers or time-domain audio buffers. The remaining 128 KB is on the main AHB bus for DMA and peripheral access. If the application needs more than 192 KB of RAM, the EBI/EMI interface can drive external SRAM, PSRAM, or NOR Flash up to 32-bit wide. That bus runs at up to 60 MHz, so it adds latency but keeps the memory map flat. For production planning, that means no forced redesign or end-of-life inventory hoarding. ## Sourcing this STM32F405VGT6 for your BOM For a production BOM line, the active lifecycle and wide distributor reach mean you can dual-source through multiple channels without redesign risk.","metaTitle":"STM32F405VGT6 STM32F4 MCU, 168MHz, 1MB Flash, 100-LQFP","metaDescription":"STMicroelectronics STM32F405VGT6 ARM Cortex-M4 MCU: 168MHz, 1MB Flash, 192KB SRAM, 82 I/O, 12-bit ADC/DAC, -40 to 85°C.","metaKeywords":null},"attributes":{"series":"STM32F4","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"168MHz","Series":"STM32F4","Package":"Tray","RAM Size":"192K 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, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"82","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":"STM32F405","Program Memory Size":"1MB (1M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.9200","priceTiers":[{"qty":1,"price":"$13.92000","currency":"USD"},{"qty":10,"price":"$12.78900","currency":"USD"},{"qty":25,"price":"$12.25840","currency":"USD"},{"qty":90,"price":"$10.80078","currency":"USD"},{"qty":270,"price":"$10.27063","currency":"USD"},{"qty":450,"price":"$9.60802","currency":"USD"},{"qty":990,"price":"$8.81287","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ba3a059be9cfe6bdf7cf0dbd3dcfbee9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F405VGT6/alternatives.json"},"ai":{"faq":[{"question":"Does STM32F405VGT6 have internal ADC?","answer":"Yes, it integrates a 16-channel 12-bit ADC and a dual 12-bit DAC.
