The 144-UFBGA package (7x7 mm) keeps the footprint small, but BGA rework needs a hot-air profile and careful bake if the moisture barrier has been opened past the floor-life window.
The internal oscillator is available, but for timing-critical USB or CAN applications, an external crystal is the usual choice to keep jitter within the spec.
Both parts run the same ARM Cortex-M7 core at 216 MHz and share the same 144-UFBGA package and pinout. The STM32F723ZEI6 includes additional cache memory and a few extra peripheral features compared to the STM32F722ZEI6, but the exact delta is in the STM32F7 reference manual. For a drop-in replacement check, verify the peripheral list against your firmware configuration.
Yes, the STM32F723ZEI6 has an internal oscillator that can serve as the system clock source. However, for applications requiring precise timing — such as USB or CAN communication — an external crystal is recommended to meet the jitter and accuracy requirements of those protocols.
