The DA16200 SoC is the world's first Wi-Fi SoC delivering year plus battery life for always connected Wi-Fi IoT devices. DA16200 is low power Wi-Fi networking SoC that delivers a dramatic breakthrough in battery life even for devices that are continuously connected to the Wi-Fi network. In most applications, one year plus battery life is achievable. There is no tradeoff in output power or range as the SoC’s range is industry leading. The chip also features very strong IoT security, including WPA3 and TLS for authentication and encryption at Wi-Fi and higher stack layers. The DA16200 is a full offload device, meaning the the entire Wi-Fi and TCP/IP networking stack and even end product application code can run on chip with no external CPU or MCU required. Alternatively, a small inexpensive MCU can send the DA16200 commands and the SoC will still perform the full offload networking stack functions.
The DA16200 modules are the perfect complement to the DA16200 ultra low power Wi-Fi SoC.

DA16200MOD-AAC4WA32
Posted by Nivethitha 84 points 8 repliesHi,
What is the value of idle current in DA16200MOD-AAC4WA32 and How to configure it ? Which of the sleep mode 1/2/3 is similar to Idle current (i.e, MCU is ON, Wifi is OFF)?
Thanks and Regards,

Hi,
Thanks for your reply.
We are looking to evaluate this for our application, Continuous ECG Monitoring with Single Module (both MCU and Network processor).
From datasheet, we are not clear about the power consumption when the MCU unit is Active and Network Processor is in Sleep State.
Could you confirm the power consumption in this mode.

Hi Nivethitha D,
Thanks for your comment. Let me check this internally and I'll get back to you ASAP.

Hi Nivethitha D,
As you can see from the datasheet (see also my first reply), the sleep current of each sleep mode are :
sleep 1: 0.2uA
sleep 2: 1.8uA
sleep 3: 3.5uA
MCU is off in all the above sleep modes. When MCU is on, the current will be several mA.
Do you need the MCU always ON?
Would it be possible to provide more information about the application / use cases, so we can get back with the proper recommendations?
Thanks, PM_Dialog

Hi,
In our application, We need a Single module with both MCU and Network Processor and the two cases we require are:
1)What is the value of current consumption of the module when the MCU is ON, WIFI is OFF ?(when WIFI is OFF, data is stored in External flash memory)
2)What is the value of current consumption of the module when both the MCU and WIFI is ON ?
MCU should be always ON.
Is it not possible to keep MCU ON and WIFI OFF ? Is there any modules which has modes other than sleep modes in which we can keep MCU ON and WIFI OFF ?
Thanks and Regards,

Hi Nivethitha.D,
2. What is the value of current consumption of the module when both the MCU and WIFI is ON ?
[DLG] - Please check table 13 in the DA16200MOD datasheet v3.1. This is the Active State. Normally the active current is about 30~40mA (w/Rx) and it would be about 300mA for Tx. These include both WiFi and MCU current.
We are still checking the other questions.
Thanks, PM_Dialog

Hi Nivethitha.D,
With regards to question #1 :
The current consumption is varied by CPU clock and CPU loading.
Please refer to the attached graph. (This result doesn't include the interface.)
The current consumption of 80MHz (typical clock) and 50% CPU loading is about 8mA.
With regards to question #3, we are still checking this.
Thanks, PM_Dialog

Hi Nivethitha,
Thanks for coming and posting on our WiFi forums.
By the idle mode, I assume that you mean what is the current consumption when the device is just sleeping (between beacons) . According to table 14 in DA16200MOD Datasheet:
- In sleep mode 1, power consumption is 0.2 μΑ
- In sleep mode 2, power consumption is 1.8 μΑ
- In sleep mode 3, power consumption is 3.5 μΑ
Detailed description for the 3x Sleep modes can be found in chapter 6.2 Low Power Operation Mode in the datasheet.
Are you using the SDK or the AT Commands to configure the DA16200MOD into sleep mode?
Thanks, PM_Dialog
