HDMI-CEC, IrDA, LINbus, MDIO, and SWPMI round out the connectivity for industrial, consumer, and telecom applications. On-chip data converters include 20-channel 16-bit ADC and three 12-bit DAC channels. ## Obsolete — sourcing through independent distribution The STM32H7A3NIH6Q carries an Obsolete lifecycle status. ## Package and temperature grade — design-in notes The 216-TFBGA (13x13 mm) is a fine-pitch BGA requiring controlled reflow profiling and X-ray inspection post-solder. Supply voltage spans 1.62 V to 3.6 V.","metaTitle":"STM32H7A3NIH6Q ARM Cortex-M7 MCU, 280 MHz, 2 MB Flash","metaDescription":"STMicroelectronics STM32H7A3NIH6Q 32-bit ARM Cortex-M7 MCU, 280 MHz, 2 MB Flash, 1.4 MB RAM, 216-TFBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"280MHz","Series":"STM32H7","Package":"Tray","RAM Size":"1.4M 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, HDMI-CEC, I²C, IrDA, LINbus, MDIO, MMC/SD/SDIO, SAI, SPDIF, SPI, SWPMI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"166","Core Processor":"ARM® Cortex®-M7","Package / Case":"216-TFBGA","Product Status":"Obsolete","Data Converters":"A/D 20x16b; D/A 3x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32H7A3","Program Memory Size":"2MB (2M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"216-TFBGA (13x13)","Voltage - Supply (Vcc/Vdd)":"1.62V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.8717","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6fa8eb8a508b65514a15c8fd6a6bee44.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is STM32H7A3NIH6Q obsolete or end of life?","answer":"Yes, the STM32H7A3NIH6Q is listed as Obsolete.
