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.
