72 MHz supports a CANopen stack with a USB virtual-comport bridge. 64 KB Flash holds a moderate application; 20 KB RAM handles data buffers and a small RTOS heap.
The STM32F103T8U7 carries an Active status from ST, though some distribution channels flag end-of-life indicators for the T8 density variant in this package.
ST lists the STM32F103T8U7 as Active, though some channel data shows an end-of-life indicator for this density/package combination. The part is available to order through independent distribution; submit an RFQ for current lifecycle confirmation and stock position.
The STM32F103T8U7 is rated for -40°C to 105°C, covering industrial and automotive under-hood environments without derating.
It comes in a 36-VFQFPN (6x6 mm) with an exposed pad — a compact surface-mount package that requires reflow soldering.
The STM32F103C8T6 has the same 64 KB Flash and 20 KB RAM but in a larger LQFP-48 package with 37 I/O, while the T8U7 is a 36-VFQFPN with 26 I/O. The C8T6 is easier to hand-solder and has more GPIO; the T8U7 saves board space.
The core runs at 72 MHz, which is the maximum for the STM32F103 series.
