STM32G474 Flash wait states at 170MHz CPU clock

Oblomkov.Ilya · ‎2020-04-09

RM0440 Rev 3 (last version) recomend to set 4WS for 170MHz CPU clock

RM0440 Rev 2 recomend to set 8WS for 170MHz CPU clock

ST driver library (STM32G4xx_HAL_Driver) function LL_PLL_ConfigSystemClock_HSE() set 8WS for 170Mhz clock.

Which Flash WS setting is right for 170MHz, 4WS or 8WS?

Yes, the 4 WS applies to all G4 products.

Thanks to the new Wait State Matrix, we have + 70% performance increase when code is running from Flash in dual bank mode (64-bit) .
