The STM32F427VGT6TR: The 1 MB Flash and 256K x 8 SRAM support double-buffered data streams and an RTOS heap.
The 100-LQFP (14x14 mm body) has 82 I/O lines that route out on two or four layers.
For production planning, the STM32F427 series is a current, supported portfolio from ST — no need to qualify a replacement or stockpile against a phase-out.
The two are electrically identical — the only difference is the shipping medium. STM32F427VGT6TR comes in Tape & Reel packaging for pick-and-place assembly lines, while STM32F427VGT6 ships in trays. Both are the same 100-LQFP package with the same 180 MHz Cortex-M4 core, 1 MB Flash, and 256K x 8 SRAM.
The STM32F427xx reference manual and datasheet are available from STMicroelectronics' website under the STM32F4 series documentation. The base product number for this device is STM32F427.
