The peripheral set includes DMA, motor-control PWM, a temperature sensor, and watchdog timers — enough for a single-chip motor drive or a fieldbus node with CAN and USB. ## Active lifecycle — no end-of-life clock","metaTitle":"STM32F103VET6 STM32F1 ARM Cortex-M3 MCU, 72 MHz","metaDescription":"STMicroelectronics STM32F103VET6 32-bit MCU, 72 MHz, 512 KB Flash, 64 KB RAM, 80 I/O, 100-LQFP.

The STM32L151CBU6A has fewer I/Os (37) and a different package (UFQFPN-48), so a board redesign is needed for a drop-in swap. For a pin-compatible replacement within the same STM32F103 family, the STM32F103VET6 shares its footprint with other 100-pin STM32F103 variants, but the Flash and RAM sizes differ."},{"question":"What is the difference between STM32F103VET6 and STM32F103ZET6?","answer":"The STM32F103ZET6 is a 144-pin variant with 144 I/Os and 512 KB Flash, compared to the STM32F103VET6's 100-pin, 80-I/O package. Both run at 72 MHz with the same Cortex-M3 core and peripheral set. The ZET6 is the choice when more GPIO or a larger BGA-compatible footprint is needed; the VET6 fits a smaller board area."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F103VET6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F103VET6 when reusing this data.
