The STM32F429BIT6: 24-channel 12-bit ADC and 2-channel 12-bit DAC are integrated.
The 208-LQFP package (28x28 mm body) is a large fine-pitch QFP — standard for hand-assembly and reflow, but the 0.5 mm pitch means your PCB fab needs good registration and solder-paste stencil alignment.
The STM32F429VIT6 is a different package variant (LQFP-100 vs the BIT6's LQFP-208) with fewer I/Os and different pin mapping. They share the same core and memory options but are not pin-compatible — a board redesign would be required to swap between them.
