Specifications of STM32F417IE

• Core: ARM 32-bit Cortex™-M4 CPU with FPU, Adaptive real-time accelerator (ART Accelerator™) allowing 0-wait state execution from Flash memory, frequency up to 168 MHz, memory protection unit, 210 DMIPS/1.25 DMIPS/MHz (Dhrystone 2.1), and DSP instructions
• 3×12-bit, 2.4 Msps A/d Converters: up to 24 channels and 7.2 MSPS in triple interleaved mode
• General-purpose Dma: 16-stream DMA controller with FIFOs and burst support
• Up To 17 Timers: up to twelve 16-bit and two 32-bit timers up to 168 MHz, each with up to 4 IC/OC/PWM or pulse counter and quadrature (incremental) encoder input
• 10/100 Ethernet Mac With Dedicated Dma: supports IEEE 1588v2 hardware, MII/RMII
• Cryptographic Acceleration: hardware acceleration for AES 128, 192, 256, Triple DES, HASH (MD5, SHA-1), and HMAC
• Rtc: subsecond accuracy, hardware calendar

Electrical characteristics
Table 12.
1. The number of wait states can be reduced by reducing the CPU frequency.
2. If an inverted reset signal is applied to PDR_ON, this value can be lowered to 1.7 V when the device operates in a reduced
3. Prefetch is not available. Refer to AN3430 application note for details on how to adjust performance and power.
4. Thanks to the ART accelerator and the 128-bit Flash memory, the number of wait states given here does not impact the
5. The voltage range for OTG USB FS can drop down to 2.7 V. However it is degraded between 2.7 and 3 V.
