This variant comes in a 64-ball TFBGA (5x5 mm), not the more common LQFP-64.
There is no LTB notice or obsolescence risk on this line. For dual-sourcing flexibility, the LQFP-64 packaged STM32F103RBT6 is a functional equivalent — same core, memory, and peripherals — though the package differs, so the PCB footprint must match.
The STM32F103RBT6 is a functional equivalent with the same core, 128 KB Flash, and 20 KB RAM, but it comes in an LQFP-64 package rather than the 64-TFBGA. The pin functions are the same, but the footprint is different — the BGA and LQFP-64 are not drop-in replacements on the same PCB layout.
