At 72 MHz the Cortex-M3 delivers about 1.25 DMIPS/MHz, enough for real-time control loops and moderate protocol stacks. The 512 KB Flash needs zero wait states up to 24 MHz; above that the flash controller inserts one wait state per the clock tree setup. If you're porting code from a lower-speed part, budget for the flash latency adjustment in the startup routine or the first branch will hard-fault. ## 112 I/O and peripheral mix — what connects where With 112 I/O in a 144-LQFP package, this part handles parallel LCD buses, multiple UARTs, and CAN nodes without external GPIO expanders. The peripheral set includes two 12-bit ADCs (21 channels), two 12-bit DACs, motor-control PWM timers, and a USB 2.0 full-speed device. The 64 KB SRAM is adequate for a small RTOS heap and double-buffered ADC data; if you need larger frame buffers, consider the STM32F105/107 series with 64 KB SRAM plus external memory interface. For production planning this means standard lead times through distribution and no forced redesign horizon. The part is ROHS3 compliant.","metaTitle":"STM32F103ZET6 32-bit ARM Cortex-M3 MCU, 72 MHz, 512 KB Flash","metaDescription":"STM32F103ZET6 MCU: ARM Cortex-M3, 72 MHz, 512 KB Flash, 64 KB SRAM, 112 I/O, -40 to 85°C.","metaKeywords":null},"attributes":{"series":"STM32F1","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.1300","priceTiers":[{"qty":1,"price":"$12.13000","currency":"USD"},{"qty":10,"price":"$11.14900","currency":"USD"},{"qty":60,"price":"$10.68733","currency":"USD"},{"qty":120,"price":"$9.41633","currency":"USD"},{"qty":240,"price":"$8.95421","currency":"USD"},{"qty":480,"price":"$8.37650","currency":"USD"},{"qty":960,"price":"$7.68327","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/72e2217711e2aa33719949448f146656.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F103ZET6/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32F103ZET6 and STM32F103VET6?","answer":"Both are STM32F103 series parts with the same core, speed, and memory.
