it will not make big changes in its properties, but indeed a little mismatching and mistuning would occur. 天线的有效长度较小约为2%,而且它的阻抗也会减少相同的金额。
By applying and tuning the antenna matching network this variation could be compensated for. Not sure it's worth the trouble. A housing around your design will have more impact on the antenna performance.
我正在寻找一个具有良好性能和尺寸小的天线解决方案。 Where i looked into Reference design as below: - Proximity Tag - 电池供电的信标均具有PCB跟踪天线(类似于MIFA)
I would like to know, Which of this reference design has better antenna performance, so that i can follow the respective reference design? 如果您可以提供相同的一些测试报告,那将是很棒的。
Information regarding the performance of the printed antena's used on the reference designs can be found in the AN-B-027 document, in that document different antenna implementations are examined and evaluated, measurements regarding the Return Loss and Radiation Patterns are attached for every antenna that is referenced on the document.
You will be able to find the all the available schematics for the 583 duaghterboard, if you choose from the products link the 14583 option and then navigate to the Development kits tab, choose the pro or the basic kit, and at the bottom of the page you will find the schematics, gerbers, BOM and Layout files of the board.
Yes the ADC reference as defined in the datasheet is 1.2V and with the X3 attenuator reaches up to 3.6V.
No, the 58x family isn't equiped with Brownout detection of Voltage supervisor.
- For Vbat<2.5V, Does it means SoC should not be rebooted from either OTP or Internal Flash memory?
- As mentioned in DA14580, it has some issue as "Using P1-2, P1-3 pins as toggling this GPIo increases PER in RF performance", Is there any such precaution required in DA14583 or this issue is resolved here?
-Regarding operating at VBAT<2.5V, the device will work, but this is the voltage threshold that Dialog guarantee's that the device will operate without any issues.
- I do understand that DA1458x can measure battery voltage without any external pin input(connection). But in our application, I have two batteries to be monitor as below: 1)一个电池CR2032将为DA14583 SOC供电,用于测量此电池电量,我可以使用该内部ADC功能。 2)第二CR2032将供电外部应用电路,测量第二电池电压电平,我是否需要具有1.2V的外部电阻分压器,或者可以使用内部3xatt箱吗?为实现这一目标是有任何特定的引脚或可以使用任何ADC频道?
- Our concern for VBAT<2.5V, is as below: 1) So as per your suggestion, DA14583 will work upto VBAT=2.35V instead of VBAT=2.5V. Am i getting it correct? 2)vbat <2.5V时冷靴的限制是仅适用于OTP内存或内部闪存的限制? 3)我们不打算使用DA14583的OTP内存(仅使用内部闪存-1Mbit),是否存在在VBAT <2.5V的情况下适用的问题?
The internal reference of the ADC is 1.2V with the attenuator can reach about 3.6V so, you can use the internal attenuator if the battery is up to 3.6V.
关于VBAT,如上所述,设备操作时,如果用户使用或不使用OTP(583使用OTP order to read some values from the OTP header and also in order to mirror the bootloader of the 583 which is burned in the OTP).
Yes you could use an external supervisor IC, if used you can avoid going in undefined states when the power rails is over or under voltaged in cases when replacing the battery etc.
In my application, I want to measure battery voltage at certain minutes(15minutes). And my Beacon advertising is at 100msec. 我是否能够在扩展睡眠模式下放置SOC,并运行15分钟的计时器,之后它可以唤醒MCU并执行电池测量?

Hi svl0822,

最好的问候,bb_dialog。
对话框支持。
Hi BB_Dialog,
我的制造商告诉我,没有NC钻机层。所以他们不能产品。
你能祝我发给我关于PCB跟踪天线参考设计的格柏文件吗?
aaron.xu@ohtcom.com.
问候,
Aaron
嗨Ohtcom,
You can find the PCB trace antenna ref des in the Reference design tab in the trace antenna PCB.

嗨mt_dialog。
Thanks for your quick support, It will help us on antenna design.
Apart from this can you please help me on below query:
- 我想得到da14583开发套件原理图设计文件参考,可以提供相同的吗?
- 正如我们想要测量2个单独的电池(CR2032)电压电平,那么将通过内部VBAT3电池电平测量来测量。对于另一个,我们需要将VBAT连接到ADC与电阻vidider。您能否确认内部ADC参考将在1.2V时?
- Does DA14583 support Brownout or Voltage supervisor? To keep SoC in Reset state while VBAT is below threshold.
Looking for your quick support.

Hi MT,
谢谢你的持续支持,
如上所述,它具有内部ADC REF = 1.2V与attenuatorx3,
- 是否可以将CR2032(3V)Dirrectly连接到ADC输入引脚以测量电池电量,而无需任何外部电阻驱动器(并且为该ADC输入引脚启用3X衰减器)?是否有任何特定引脚,或者可以从p0 [0-3]中选择它?
- 在数据表中,如果VBAT <2.5V,则应避免DA14583冷启动。这是否意味着在Vbat <2.5V以下,SoC不起作用?
- For Vbat<2.5V, Does it means SoC should not be rebooted from either OTP or Internal Flash memory?
- As mentioned in DA14580, it has some issue as "Using P1-2, P1-3 pins as toggling this GPIo increases PER in RF performance", Is there any such precaution required in DA14583 or this issue is resolved here?
Hi Bimalsinh,
- 您不必使用任何端口/引脚才能测量电池电压,58倍具有用于测量内部电压和电池电压的附加通道,如果您看看SDK中的Peripheral_examples,您将找到一个示例测量电池电压并使用内部通道,或者您可以在数据表中查找,并检查GP_ADC_CTRL_REG和GP_ADC_SEL字段。
-Regarding operating at VBAT<2.5V, the device will work, but this is the voltage threshold that Dialog guarantee's that the device will operate without any issues.
-I dont get the question, can you please clarify.
- 对于PIN P1_2和P1_3的PINS P1_2和P1_3仅适用于583的预防措施相同的预防措施是因为它仅在QFN封装中可用。
Thanks MT_dialog

- 正如DA1458x没有内置的da1458x,它可以不使用外部衰褐电压超级icon吗?如果我不使用衰褐器IC,可能会发生什么?(我们在产品中有更换的电池)
Hi MT,
Awaiting your quick response here, to finalize the BLE SoC selection.
Hi Bimalsinh,
The internal reference of the ADC is 1.2V with the attenuator can reach about 3.6V so, you can use the internal attenuator if the battery is up to 3.6V.
关于VBAT,如上所述,设备操作时,如果用户使用或不使用OTP(583使用OTP
order to read some values from the OTP header and also in order to mirror the bootloader of the 583 which is burned in the OTP).
Yes you could use an external supervisor IC, if used you can avoid going in undefined states when the power rails is over or under voltaged in cases when replacing the battery etc.
Thanks MT_dialog
Hi MT,
I would like to have your feedback on below quick questions:
Battery Measurement:
- 测量电池电压时,目前ADC引脚的消耗量是多少?
- 内部3x衰减器的当前要求是什么?(这将是电动高效的内部3x衰减器或外部电阻驱动器?)
能量消耗:
- 是否有任何计算表或找到DA14583 SOC的功耗的方法?(广告Inteval:100msec,Databyte:31字节)
Hi Bimalsinh,
- ADC在100 kSamples上具有5uA的典型电源电流,关于当前要求(如数据表中提到的)在有或没有衰减器的情况下,ADC的阻抗是无限的,并且随着衰减器约为300K,所以是什么更高效(有或没有和外部volatge分频器)取决于您的应用程序。
- No, there is no power consumption sheet indicating the power consumption of the 583 in different advertisiing intervals.
Thanks MT_dialog
Hi MT,
In my application, I want to measure battery voltage at certain minutes(15minutes). And my Beacon advertising is at 100msec.
我是否能够在扩展睡眠模式下放置SOC,并运行15分钟的计时器,之后它可以唤醒MCU并执行电池测量?
Hi Bimalsinh,
是的,您将能够这样做,可以通过ke_timer(app_easy_timer)触发ADC测量,定时器具有约5分钟的最长时间计数,因此每次5分钟超时时间都会启动计时器再次计时器并计算定时器已过时的计时器,在第3次中,您可以将计数器设置为零并触发ADC测量。
Thanks MT_dialog
Hi MT,
感谢您的及时回应,
因此,在My Timer运行时(5分钟)CPU将处于扩展睡眠模式。我理解是否正确?
另外一个问题,我没有找到使用特定主题添加新帖子的任何简单方法。你能引导我吗?
Hi Bimalsinh,
设备启用睡眠模式时,它将在广告事件之间睡眠,当您设置KE_TIMER时,基本上您将设备编程为在指定时间内唤醒,以便为您的回调设置,所以在上面的回调实现该设备将在广告间隔之间睡眠(它需要醒来才能宣传),并且它将尽快唤醒,而您经历过的计时器。
