Wireless:
Wi-Fi: 802.11 b/g/N
Bluetooth: v4.2 BR/EDR and BLE
Peripheral Interfaces:
12-bit ADC up to 18 channels
2 × 8 bit DAC

Answer 1

It's just a fixed background that changes depending on the scroll.
That is, through display: none / block they hide / show. However, everything.

Answer 2

What does 32-bit mean

That the microcontroller in its machine codes can operate with 32-bit values. The register size is 32 bits.

And if you say 32 bit, isn't it the same thing?

Yes, it's the same. 32 bits of data fit in one register. 32 bits in the register.

Memory: 520 KB SRAM

Inside the microcontroller, 520 KB SRAM is built in.

Wi-Fi: 802.11 b/g/n, Bluetooth: v4.2 BR/EDR and BLE

The chip has a built-in WiFi / BT hardware module, no need to connect anything extra to ensure wireless communication

12-bit ADC up to 18 channels

The controller can measure the voltage on its 18 outputs with an accuracy of 12 bits, thereby converting the analog signal into digital

2 × 8 bit DAC

The controller is able to generate voltage on its two outputs with an accuracy of 8 bits, thereby creating an analog signal

Answer 3

32 bits is the physical implementation, most commonly an ALU. But the rest of the architecture can be 16-bit. Or, for example, a 64-bit bus can be.
Therefore, there will be no unambiguous answer until they indicate the bit depth of what is meant, and if so, then it cannot be said that the bit depth is equal to the bit depth.
520 KB of SRAM - means that you don't implement a lot of functionality. And if there is no mention of FLASH , then the program will also be executed from RAM. This means you need an external memory chip with boot FLASH.
Wi-Fi: 802.11 b / g / n - means that there is no 5 GHz band. Those. the chip is relatively slow. It is also not indicated in which band 20 or 40 MHz can operate. Those. here, too, uncertainty remains.
Bluetooth: v4.2 BR/EDR and BLE - indicates potential problems with WiFi and the possible need for an external antenna switch chip. Version v4.2 also means a slightly outdated standard inferior in speed and range to v5. There is also uncertainty here as it is not clear what profiles are supported and how it coexists with WiFi
12-bit ADC up to 18 channels - only 12-bit resolution is indicated, the accuracy and speed of this ADC remain unclear. Typically, the accuracy of such built-in ADCs is at the level of 8 bits at a frequency of 1 kHz.
2 × 8 bit DAC - the settling rate and the amplitude of parasitic bursts are also not clear here.
In a word, it is almost impossible to navigate according to these data if this chip is compared with something else, since all the features are very typical in the first approximation and many have such an assortment.
