7.2

Wi-Fi Processor

DA16200 includes an internal MCU (Arm Cortex-M4F) to completely offload the host MCU along with

an 802.11 b/g/n radio, baseband, and MAC with a powerful crypto engine for a fast and secure

WLAN and Internet connections with 256-bit encryption. It supports the station, SoftAP, and Wi-Fi

Direct modes. It also supports WPA/WPA2 personal and enterprise security, WPA2 SI, WPA3 SAE,

OWE, and WPS 2.0. It includes an embedded IPv4 and IPv6 TCP/IP stack.

Memory

7.3.1

Internal Memory

DA16200 contains four types of internal memories and also supports an external serial flash memory

interface. The roles and functions of each memory are described in the following subsections.

7.3.1.1

ROM

This memory contains boot loader, system kernel, network stack, and various kinds of drivers for

interfaces and peripherals.

7.3.1.2

SRAM

SRAM memory is used only as data space for the applications which run on the internal CPU. The

applications execute directly from serial flash using an execute in place (XIP) process which loads

the code into I-Cache as required. The SRAM is volatile memory and its contents will disappear when

in the low-power Sleep mode.

The address range of the internal SRAM is from 0x0008_0000 to 0x000F_FFFF, and the controller of

this memory supports the swap operation for the internal CPU. To do a swap operation of the

controller, add the offset value to the SRAM address for read operation only.

If the offset value is 0x2080_0000, the controller will do a swap to reverse the byte order for a scalar

32-bit value. If the offset value is 0x2040_0000, the controller will do a swap to reverse the halfword

(16-bit) order for a scalar 32-bit value. For example, if the value of address 0x0000_8000 is

0x12345678, reading address 0x2080_8000 will output value 0x78563412 and reading address

0x2040_8000 will output value 0x56781234.

7.3.1.3

Retention Memory

This memory is a kind of non-volatile memory and is used to save and manage essential information

that should be preserved even in the low-power Sleep mode of the DA16200.

7.3.1.4

OTP

DA16200 includes a one-time field programmable non-volatile CMOS memory (OTP). The OTP

memory array supports write accesses of 1 bit and read accesses of 32 bits by executing read/write

commands through the OTP controllers register interface.
