Layout Note:
Place RC C116 R63 C44 Close To MCU.
MicroSD CARD
FOR SD BOOT, ROM NEED SD_CD_SW PIN KEPT LOW:
CARD INSERT
Pin10_CD Connected to Pin9_GND --> SD_CD_SW =LOW
CARD OFF
Pin10_CD Float --> SD_CD_SW =HIGH
SDRAM 32MB
1V8 HyperFlash 64MB
1V8 QSPI Flash 8MB
Option 1: USE HyperFlash (DNP U11 and series R)
MAX 150 mA @3.3V
MAX 180 mA @1.8V
Layout Note:
The SDRAM interface (running at up to 166 MHz):
Review Note:
1. The SDRAM routing must be separated into three groups: data, address, and control.
2. Route all signals at the same length within 100 Mils.
3. The controlled impedance for the single-ended traces must be 50 Ω.
The SD module interfaces (running at up to 50 MHz):
1. Follow similar SDRAM rules for data, address, and control as for the SD interfaces.
Layout Note:
The FlexSPI interface (HyperFlash, QSPI Flash, running at up to 166 MHz):
1. Follow similar SDRAM rules for data, address, and control as for the FlexSPI interfaces.
2.
有分叉的信号，走
"T"
型拓扑结构，即分叉电阻按
"T"
型放置，且两个电阻放到一起，确保尾巴尽量短。
3.
需放到一起的电阻包括：
R105 and R104, R98 and R96, R113 and R114, R112 and R116, R108 and R106, R111 and R115
。
Layout Note:
Place R15 Close To MCU.
4.
以下信号组，需要控制等长：
FlexSPI_SS0 + QF_SS0 ,
FlexSPI_CLK + QF_CLK,
FlexSPI_D0_A + QF_D0_A,
FlexSPI_D1_A + QF_D1_A,
FlexSPI_D2_A + QF_D2_A,
FlexSPI_D3_A + QF_D3_A.
FlexSPI_SS0 + HF_SS0 ,
FlexSPI_CLK + HF_CLK,
FlexSPI_D0_A + HF_D0_A,
FlexSPI_D1_A + HF_D1_A,
FlexSPI_D2_A + HF_D2_A,
FlexSPI_D3_A + HF_D3_A.
FlexSPI_DQS + HF_DQS,
FlexSPI_CLK_B,
FlexSPI_D0_B,
FlexSPI_D1_B,

FlexSPI_D3_B
BOM Note:
Flash_RST is 3.3V IO, DNP R101 when
the power supply voltages of HyperFlash U7 is 1.8V.
Option 2: USE QSPI FLASH (DNP U7 and series R)
