STM32F417IGT6

STM32F417IGT6 is an STMicroelectronics high-performance STM32F4 microcontroller shown as Active on the ST product page: an Arm Cortex-M4F core at 168 MHz with DSP instructions and a single-precision FPU, 1 MB of Flash, 192 KB of SRAM plus 4 KB of backup SRAM, and the ART Accelerator for zero-wait-state execution from Flash, in a 176-pin LQFP package with up to 140 I/Os. The F417 is the connected and secured variant of the foundation line: it adds a 10/100 Ethernet MAC with IEEE 1588 support and a hardware cryptographic processor (AES, DES/TDES, SHA-1 and MD5) on top of the F407 peripheral set, which also includes a camera interface (DCMI), FSMC external memory control, two CAN 2.0B controllers, USB OTG and multiple SPI/I2C/USART interfaces. The selection point is hardware crypto plus Ethernet in the largest pin count: designs that terminate TLS or sign firmware on-device avoid the software-crypto performance and code-size cost. Selection advice: choose the F417 over the F407 when the cryptographic accelerator or Ethernet is a stated requirement; choose the F427/F429 line instead when a Chrom-ART accelerator or LCD-TFT controller is needed, and confirm the T6 tray code against your assembly process since ST also offers tape-and-reel variants of this package.
