40. Maxim's MCU is indeed superior in performance, especially low power consumption. I ordered a high-performance biosensor kit from the official website for ECG data reading. After testing, I found that the problem was that this chip needs 2 power rails to support it, of which 1.8V is not a common power configuration, and the others are a single 3.3V or a single battery through boost up to 3.3V. So when matching MCU, it is best to introduce the matching PMIC as well. Because Maxim's PMIC also has many specifications, it is not easy to choose a suitable one.
A: Thank you, some of Maxim's MCUs do need to be powered by multiple power supplies. The main purpose of this is low power consumption. Usually an external PMIC is required. We can consider explaining the matching PMIC later. Some MCUs only need a single power supply.
41. For IoT applications, does Maxim have a mature set of solutions?
A: Heart rate, blood pressure, ECG, etc.
42. How to calibrate the accuracy of MAX's heart rate, blood pressure, and ECG measurement MCU, or how to clarify the accuracy of these parameters?
A: Use reference equipment for testing and comparison
43. Is there a QFN package?
A: Yes
44. Does Maxim have a low-power MCU with segment LCD driver?
A: Yes, the MAX32650 series has integrated
45. Are there any 5G modules or modules at present?
A: Yes... For details, please contact our company
46. Max32666 requires a 32M crystal oscillator. What is the minimum requirement of the crystal oscillator (frequency accuracy, frequency stability, jitter, etc.)? 32M seems to be uncommon. Why choose this frequency point?
A: This is for Bluetooth. If you don't use Bluetooth, this crystal oscillator is not needed
47. Does the MCU debugging tool JLINK support it?
A: Yes
48. Does Bluetooth support MESH?
A: Yes
49. What is used for software development? Keil?
A: Keil is supported
50. What fields does the Internet of Things involve?
A: Only wearable devices, smart homes, etc.
51. The basis of IoT and AI is data. Can you talk about the method of data fusion? Especially some heterogeneous data
A: The main data will be sent to the cloud platform through the gateway for further fusion and analysis. There are also practices of developing specific edge computing after different AI calculations.
52. How can factories with multiple varieties and small batches of products achieve intelligent management?
A: Automated processes plus different sensors can provide different help in different applications.
