2.1 Introduction
The SNC7320_EV_Board_Top-V
x.x
and the SNC7320_EV_Board_Bottom-V
x.x
are a full function
development system. They provide various interfaces such as CIS, SD card, NOR/NAND flash,
SRAM, 8080 LCM, TFT LCD, Audio (I
2
S), USB (device or host), SAR ADC, SPI, I
2
C, UART, and
…etc.
for development of wide range of applications. The subsections below explain how to use each
connector and provide circuit diagrams thereof.
2.2 AC Adapter Connector and BAT Connector
There are two power processes on SNC7320 EVB. Their relative of power domain on
SNC7320_EV_Board_Bottom-V
x.x
and SNC7320_EV_Board_Top-V
x.x
can depart into two cases
below.
Case 1: Use the AC adapter connector (J2) of the bottom board to supply power to the EVB. The
bottom board converts the voltage from 7.5V to 5V with a 7805 regulator, and supplies 5V power to the
top board. The top board converts the 5V power to 3.3V and provides 3.3V power to the bottom board
and the peripherals connected to it.
