Product details

The STM32F103T6U7A: Integrates peripherals including DMA, motor-control PWM, a 10-channel 12-bit ADC, and connectivity such as CAN, I2C, SPI, and USB — a fit for industrial motor drives, sensor hubs, and cost-sensitive embedded control where the 72 MHz core handles real-time loops without external logic.

Package and footprint — 36-VFQFN exposed pad

The 36-VFQFN (6x6 mm) with exposed pad requires a thermal-via array under the die attach pad for heat dissipation. Surface-mount only — no through-hole version exists.

Lifecycle and supply chain

Listed as Active by STMicroelectronics with no NRND or EOL notice. The STM32F1 series is widely second-sourced through the open-market channel, but no pin-compatible official alternate is recorded in this listing.

Frequently asked questions

Is STM32F103T6U7A obsolete or active?

It remains available for new designs and production orders.

What is the closest pin-compatible alternative to STM32F103T6U7A in this component family?

Within the STM32F103 value-line density options, pin-compatible parts include the STM32F103C8T6 (64 KB Flash) and STM32F103RBT6 (128 KB Flash) in the same 36-VFQFN footprint — both share the same core, peripherals, and supply range but offer larger Flash for code expansion. No official cross-reference is recorded for this specific variant.
