The attachment is The schematic diagram of DA14531 connecting flash, which I designed, is this The connection method correct?If it is not correct, may the DA14531 connect to the flash must be connected as follows and always be changed?P0_0 is connected to SI, P0_1 is connected to CS#, P0_3 is connected to the SO, and P0_4 is connected to the SCLK. If it is connected in the above way, can the reset circuit be designed as the "reset" circuit in the schematic,, because I have three ICs that need to be reset by the hardware, of which the ASIC and the communication transmission module are both low level reset, and DA14531 is high - power Pin P0_0 is connected to Q1. The When SW1 is closed, can DA14531 be reset?Thank you very much for your help and wish you a happy life.

Hi MrWeng,
Which kind of 亚博电竞菠菜products you are going to apply the design?Does it require the for a long range broadcast?
In the scheme:
1. The DCDC converter setup, the capcacitor values are not the same as the suggesion.
2. Without matching network of can Antenna order to be used lead to a decrease performance on broadcasting had.
3. The GPIOs could be configured for any function.
4. For the Reset Circuit, POR pin need to pull - down after booting and ready For a pull - high operation For Reset. More details we order to discuss internally and reply you later.
Best regards,

Hi, has any:
Our products are through data communication module and the bluetooth transmission sensor collected data.In this product, the bluetooth portion of the circuit design, please refer to the DA14531 QFN/BypassHardware design instance.In the latest design, we changed the reset circuit, as shown in attachment.SW3 button, MCU and data communication module will be low level and reset, and DA14531 will become a high level and reset.I don't understand "need long-distance radio?"The meaning of.In your reply?Is it a remote air upgrade?Please help us to point out that new design of the unreasonable place, so that we can make improvements.
Hi Mr. Weng,
Can your product PCB layout file, BOM list and scheme file shall be sent to my mailbox?My email isQifan.Guo@diasemi.com
Also please introduce your product in the mail and related agency information.
Best regards,
