If the end system sees sustained ambient above 85°C, check whether the extended-temperature variant (STM32F103ZDT6 with a '7' suffix) is available; this listing is the standard industrial grade. ## Analog and connectivity peripherals Connectivity includes CANbus, I²C, SPI, UART/USART, USB, and IrDA, so it can serve as the central node in a distributed control network or a gateway between a CAN fieldbus and a USB host. ## Supply voltage and power management Built-in peripherals include a power-on reset (POR), power-down reset (PDR), and programmable voltage detector (PVD), which simplify the power sequencing and brown-out handling on a multi-rail board. ## Active lifecycle — no obsolescence signal The STM32F1 series is a mature, volume-production line with no last-time-buy notices or end-of-life announcements for this density. That makes it a safe choice for production programs with a multi-year horizon, though the usual allocation watch applies during tight market cycles — the STM32F1 has seen spot premiums in past shortages.","metaTitle":"STM32F103ZDT6 ARM Cortex-M3 MCU, 72 MHz, 384 KB Flash","metaDescription":"STMicroelectronics STM32F103ZDT6 32-bit MCU with 72 MHz ARM Cortex-M3, 384 KB Flash, 64 KB SRAM, 112 I/O, 21x12-bit ADC, 2x12-bit DAC, industrial temp -40°C to","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":"STM32F1","Package":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, Motor Control PWM, PDR, POR, PVD, PWM, Temp Sensor, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"112","Core Processor":"ARM® Cortex®-M3","Package / Case":"144-LQFP","Product Status":"Active","Data Converters":"A/D 21x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F103","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":"$8.8166","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/72e2217711e2aa33719949448f146656.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F103ZDT6/alternatives.json"},"ai":{"faq":[{"question":"Does STM32F103ZDT6 have a direct replacement or equivalent?","answer":"Within the STM32F103 family, the pin-compatible density options are the STM32F103ZET6 (512 KB Flash) and STM32F103ZGT6 (1 MB Flash) in the same 144-LQFP package.
