The base product number is STM32F427, so PCN and errata tracking should be done against that root.","metaTitle":"STM32F427ZIT6TR ARM Cortex-M4 MCU, 180 MHz, 2 MB Flash","metaDescription":"STMicroelectronics STM32F427ZIT6TR 32-bit MCU, ARM Cortex-M4 at 180 MHz, 2 MB Flash, 256 KB RAM, 144-LQFP, -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":"180MHz","Series":"STM32F4","Package":"Tape & Reel (TR) Cut Tape (CT)","RAM Size":"256K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, Ethernet, I²C, IrDA, LINbus, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"114","Core Processor":"ARM® Cortex®-M4","Package / Case":"144-LQFP","Product Status":"Active","Data Converters":"A/D 24x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F427","Program Memory Size":"2MB (2M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$18.2800","priceTiers":[{"qty":1,"price":"$18.28000","currency":"USD"},{"qty":10,"price":"$16.79800","currency":"USD"},{"qty":25,"price":"$16.10200","currency":"USD"},{"qty":100,"price":"$14.18720","currency":"USD"},{"qty":250,"price":"$13.49084","currency":"USD"},{"qty":500,"price":"$12.62048","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/fa3522ede21a921b5dbbcb78f05a0a95.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F427ZIT6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32F427ZIT6TR and STM32F427ZIT6?","answer":"The STM32F427ZIT6TR is the Tape & Reel (TR) packaged variant of the STM32F427ZIT6. The silicon and the 144-LQFP package are identical; the suffix only changes the shipping medium for automated pick-and-place assembly."},{"question":"Can the STM32F427ZIT6TR be programmed with ST-Link?","answer":"Yes. The STM32F427ZIT6TR uses the standard ARM Serial Wire Debug (SWD) interface, which is supported by all ST-Link programmers and debuggers. The SWD pins (SWDIO, SWCLK) are available on the 144-LQFP package."},{"question":"What is the closest functional second-source to the STM32F427ZIT6TR?","answer":"The STM32L151CBU6A is a lower-power Cortex-M3 part from the STM32L1 series, but it runs at 32 MHz with 37 I/O and no Ethernet or external memory bus — it is not a pin-compatible or performance-equivalent replacement. For a true functional match within the STM32F4 family, look at the STM32F427VIT6 (100-pin LQFP) if you can reduce the I/O count, or the STM32F429ZIT6 which adds a TFT LCD controller in the same 144-pin footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F427ZIT6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F427ZIT6TR when reusing this data.
