7 Core System
7.1 ARM Cortex-M4F Processor
The Cortex-M4F processor is a low-power processor that features low gate count, low interrupt
latency, low-cost debug, and includes floating point arithmetic functionality. The processor is
intended for deeply embedded applications that require fast interrupt response features.
The features of the Cortex-M4F processor in DA16200 are summarized below:
■ Operation clock frequency is up to 160 MHz
■ 32-bit ARM Cortex-M4F architecture optimized for embedded applications
■ Thumb-2 mixed 16/32-bit instruction set
■ Hardware division and fast multiplication
■ Includes Nested Vectored Interrupt Controller (NVIC)
■ SysTick timer provided by Cortex-M4F processor
■ Supports both standard JTAG (5-wire) and the low-pin-count ARM SWD (2-wire, TCLK/TMS)
debug interfaces
■ Cortex-M4F is binary compatible with Cortex-M3

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.
7.3 RTC
Among the pins in DA16200MOD, four special pins are directly connected to the RTC block, which
are RTC_PWR_KEY, RTC_GPO, RTC_WAKE_UP, and RTC_WAKE_UP2.

Description
RTC_PWR_KEY
3
RTC_PWR_KEY represents a power key for the RTC block. When
this pin is enabled, the RTC starts to work by following a pre-
defined power-up sequence and eventually all the necessary
power is supplied to all the sub-blocks including the main digital
block in DA16200. When disabled, all blocks are powered off and
this mode is defined as Sleep mode 1.
Minimum leakage current in Sleep mode 1.
RTC_SENSOR
5
This pin is an output and high level is 'VBAT'.
It has three different functions.
● GPO function: output value can be set as 1 or 0 via register
setting. It can keep the value even in Sleep mode
● Flash control function: when in Sleep mode, it becomes 0;
when in Active mode, it is 1
● Sensor wakeup function: when used in sensor wake-up
function (Section 8.8.4), it provides a programmable periodic
signal for an external device. Inside the RTC, there are
registers for setting count values
