2. System Block Diagram
DNSA141 is based on QCA4002 Internet of Everything chip and QCA’s SP141 reference
board design in stamp form factor.
Inside the module, there is a QCA4002 main chip which control the WLAN RF and BB
function, also embedded a small processor which can do the encryption and TCP/IP off
load. Only few external components are necessary such as XTAL and Flash. Block
Diagram as Fig. 1:
Flash is only storing the binary code to control the QCA4002. RF calibration data is stored
inside QCA4002 OTP not this flash. QCA also move the common data such as target
power and CTL table to driver level called “Board Data File”. This can reduce the OTP size
usage.
For complex control or more GPIO demanding, customer has to use a Micro Processor to
control this module through SPI interface. QCA4004 will be in SPI slave mode.
USB interface is only for engineering RD mode such as production testing purpose or
reprogram the external flash memory.

Note A: External IO voltage (DVDD_GPIO) can be 1.8~3.4V.
Note B:QCA4002 need 3.3V and 1.2V supply. For 1.2V supply there are 2 methods: Switching and
LDO. Inside the QCA4002, there is embedded a switching regulator to convert 3.3V to 1.2V for its
chip core voltage supply. Also it has a LDO driver to act as 3.3V->1.2V LDO driver (might need
external transistor). This table we use switching regulator method to have better power efficiency.
The tradeoff is we have to add a power inductor near QCA4002 chip. Also shielding height has to
be caution to prevent the inductor magnetic field interaction with the iron material in the shielding.

installation. If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment.
This transmitter must not be co-located or operating in conjunction with any other antenna or
