The STM32F103ZET6TR: The industrial temperature range (-40 to 85°C) and 144-LQFP package make it a common choice for motor drives, PLCs, industrial HMIs, and embedded control boards that need a proven, well-supported MCU with ample memory and connectivity.
512 KB Flash and 64 KB SRAM on-chip. 112 I/O lines in the 144-LQFP package.
No last-time-buy window to track.
The STM32F103ZET6 and STM32F103ZET6TR are electrically identical. The TR suffix indicates Tape & Reel packaging for automated assembly; the ZET6 ships in trays. Both are the same silicon in the same 144-LQFP package.
The core runs at 72 MHz maximum, driven by an internal oscillator or an external crystal. At 72 MHz the Flash requires one wait state for zero-wait access.
