This means ST has formally discontinued production; no further factory orders are accepted.
The peripheral list includes a 12-bit ADC with 24 channels, two 12-bit DACs, a DMA controller, I²S audio interface, LCD parallel interface, PWM timers, and a watchdog timer. This makes the part suitable for designs that need to bridge sensor arrays, display panels, and wired networking without external bridge chips.
Yes, the lifecycle status is Obsolete. ST has discontinued production, so new orders go through surplus or broker channels. No factory lead time applies.
Within the STM32F407 series, pin-compatible density variants such as the STM32F407ZET6 (512 KB Flash) or STM32F407VGT6 (100-pin LQFP) may serve as form-fit-function alternatives, but a full BOM review is needed to confirm memory, I/O, and package fit.
The core is rated at 168 MHz, which is the maximum clock frequency for the ARM Cortex-M4 on this part.
