That means no last-time-buy deadline to manage, no PCN-driven scramble for an alternate source.","metaTitle":"STM32F303ZDT6 32-bit ARM Cortex-M4 MCU, 72 MHz, 384 KB Flash","metaDescription":"STMicroelectronics STM32F303ZDT6 32-bit ARM Cortex-M4 MCU, 72 MHz core, 384 KB Flash, 80K x 8 RAM, 115 I/O, 144-LQFP, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"STM32F3","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"72MHz","Series":"STM32F3","Package":"Tray","RAM Size":"80K 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":"115","Core Processor":"ARM® Cortex®-M4","Package / Case":"144-LQFP","Product Status":"Active","Data Converters":"A/D 40x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F303","Program Memory Size":"384KB (384K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"144-LQFP (20x20)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.3700","priceTiers":[{"qty":1,"price":"$11.37000","currency":"USD"},{"qty":10,"price":"$10.45400","currency":"USD"},{"qty":60,"price":"$10.02083","currency":"USD"},{"qty":120,"price":"$8.82908","currency":"USD"},{"qty":240,"price":"$8.39579","currency":"USD"},{"qty":480,"price":"$7.85410","currency":"USD"},{"qty":960,"price":"$7.20411","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c1aa05dbd335dffd091de829325705a6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F303ZDT6/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32F303ZDT6 and STM32F303VCT6?","answer":"The STM32F303VCT6 is a 100-pin LQFP variant of the same STM32F303 family, versus the 144-pin LQFP on the ZDT6. The VCT6 offers fewer I/O (up to 87 vs 115) and a smaller package footprint. Both share the 72 MHz Cortex-M4 core, 384 KB Flash, and the 40-channel ADC bank, so firmware porting between them is straightforward if you adjust the pin mapping."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F303ZDT6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F303ZDT6 when reusing this data.
