The information contained herein is the exclusive property of WNC and shall not be distributed, reproduced, or disclosed in whole or in part without prior written permission of WNC. 5 / 15 DNSA-141 Specification 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. Fig. 1: Block Diagram

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.  Absolute Rating
