Introduction

This document provides a set of guidelines that help users prepare schematics and PCB layouts for
products with the DA16200. Recommended schematic, chip interfaces, and surrounding components
as well as PCB layout guidelines of both devices are provided.

Guidelines of Schematic Design

The DA16200 application schematic includes the following five parts:
●
Power supply: Digital Power Supply, Analog Power Supply
●
RF: contains antenna part
●
Clock: Main Clock, RTC Clock
●
Flash interface
●
Digital I/O: GPIO pin assignment, can be changed based on application requirement
To choose the proper schematic, check the items below:
●
Package type: the DA16200 provides QFN and fcCSP packages
●
VDD of flash memory: 1.8 V and 3.3 V VDD of flash memory are possible with the DA16200.
When 1.8 V VDD of flash memory is applied, the DA16200 can control the flash memory through
VDD_FDIO/FDIO_LDO_OUT (QFN pin 20 and 21, fcCSP pin M4). When 3.3 V VDD of flash
memory is applied, additional switch is needed to control flash memory to achieve low power
●
Tx power mode: the fcCSP type can support normal or low Tx power mode. See 5.5 Current
Consumption in the DA16200 datasheet. For the application which doesn't need higher Tx power,
the low Tx power mode can be applied. The QFN type supports only normal Tx power mode. See
Sections 2.2.4 and 3.4
See Section 3 for information on each application.
