The 384 KB Flash gives room for a moderate firmware image plus an OTA staging buffer; the 64 KB SRAM supports several real-time data buffers and a modest stack. If your application needs more working memory, the STM32F3 family offers density upgrades, but for a typical mixed-signal control board — say, a three-phase motor drive with current sensing — this memory split is well matched. ## I/O and peripheral set for board-level connectivity With 51 I/O lines, the STM32F302RDT6TR can connect to multiple external sensors, actuators, and displays. The 16-channel 12-bit ADC and single 12-bit DAC cover analog front-end needs without an external converter. The internal oscillator reduces BOM count, though an external crystal can be added for tighter timing. ## Package and supply: 64-LQFP, 2V to 3.6V Housed in a 64-LQFP package (10x10 mm body), the part is a surface-mount device that reflows on standard lead-free profiles. The supply range of 2V to 3.6V lets it run from a 3.3V rail or a 2.5V rail, and it can tolerate a 3.6V absolute maximum. The 64-LQFP footprint is common across many STM32F3 variants, so a layout can often accommodate a pin-compatible upgrade or second source without a board spin.","metaTitle":"STM32F302RDT6TR STM32F3 ARM Cortex-M4 MCU, 72 MHz","metaDescription":"STM32F302RDT6TR 32-bit ARM Cortex-M4 MCU at 72 MHz with 384 KB Flash, 64 KB SRAM, 51 I/O, industrial temp -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":"72MHz","Series":"STM32F3","Package":"Tape & Reel (TR)","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"51","Core Processor":"ARM® Cortex®-M4","Package / Case":"64-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 1x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F302","Program Memory Size":"384KB (384K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.0655","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4c7220c917c6a09ac2dd5a3130dafc01.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F302RDT6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32F302RDT6 and STM32F302RDT6TR?","answer":"The two parts are electrically identical. The STM32F302RDT6TR is the Tape & Reel (TR) packaging option for automated pick-and-place assembly, while the STM32F302RDT6 ships in tray or tube. The silicon and firmware are the same."},{"question":"What are the equivalent or replacement parts for STM32F302RDT6TR?","answer":"Pin-compatible siblings within the STM32F302 base product number (same 64-LQFP footprint) offer different Flash and SRAM densities. For a direct replacement with identical memory, the STM32F302RDT6 (tray) is the same die.
