That means a single R7FA6M3AH3CBG#AC0 can act as the Modbus TCP gateway, the HMI controller driving a TFT display via the built-in LCD controller, and the data logger talking to an SD card — all on one 176-LQFP package. The 133 I/O lines leave room for sensor arrays and keypads. ## On-chip data conversion and timing Twenty-four 12-bit SAR ADC channels and two 12-bit DACs cover analog front-end needs — current sensing, potentiometer inputs, or analog output for a servo drive. The internal oscillator saves a crystal if the timing budget allows, and the DMA engine keeps the CPU free for protocol stacks. ## What the 120 MHz and 2 MB Flash mean for your BOM The 120 MHz Cortex-M4F with single-precision FPU handles FFT, filter math, and control loops in software rather than requiring a separate DSP. The 2 MB Flash is sized for a full embedded GUI library (e.g., emWin or LVGL) plus the application firmware, with room left for a bootloader and OTA update staging area. The 640 KB RAM is the headroom that keeps you from adding an external SRAM — a cost and board-area saving.","metaTitle":"R7FA6M3AH3CBG#AC0 RA6M3 ARM Cortex-M4F MCU, 120 MHz","metaDescription":"R7FA6M3AH3CBG#AC0 from Renesas: RA6M3 series, 120 MHz ARM Cortex-M4F, 2 MB Flash, 640 KB RAM, Ethernet, CAN, USB, -40 to 105°C.","metaKeywords":null},"attributes":{"series":"RA6M3","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Speed":"120MHz","Series":"RA6M3","Package":"Tray","RAM Size":"640K x 8","Core Size":"32-Bit","EEPROM Size":"64K x 8","Peripherals":"DMA, LCD, LVD, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, Ethernet, I²C, IrDA, MMC/SD, SCI, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"133","Core Processor":"ARM® Cortex®-M4F","Package / Case":"176-LQFP","Data Converters":"A/D 24x12b SAR; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"2MB (2M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"176-LFQFP (24x24)","Voltage - Supply (Vcc/Vdd)":"2.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$15.1","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$15.10000","currency":"USD"},{"qty":10,"price":"$13.87900","currency":"USD"},{"qty":25,"price":"$13.30360","currency":"USD"},{"qty":152,"price":"$11.72164","currency":"USD"},{"qty":304,"price":"$11.14635","currency":"USD"},{"qty":456,"price":"$10.42724","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/190bae1423b76dc497149ec23b19b3c0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does R7FA6M3AH3CBG#AC0 support an external memory interface?","answer":"Yes, the part includes an EBI/EMI (External Bus Interface / External Memory Interface) peripheral, allowing connection to external SRAM, NOR Flash, or parallel LCD controllers."},{"question":"What are the exact specifications of R7FA6M3AH3CBG#AC0?","answer":"Core: ARM Cortex-M4F at 120 MHz.
