Pin Description (Continued)
Pin Number
Pin Name
Type
Pin Function
36
SD9
I/O (PD)
Shared Data Bus bit 9. Data D9 access when CMD=0. Do Not Care when CMD=1. This
pin must be tied to GND in 8-bit bus mode.
37
DGND
GND
Digital ground
38
VDD_IO
P
3.3V, 2.5V or 1.8V digital VDD input power supply for IO with well decoupling capacitors.
39
SD8
I/O (PD)
Shared Data Bus bit 8. Data D8 access when CMD=0. Do Not Care when CMD=1. This
pin must be tied to GND in 8-bit bus mode.
40
SD7
I/O (PD)
Shared Data Bus bit 7. Data D7 access when CMD=0. Address A7 access when CMD=1.
41
SD6
I/O (PD)
Shared Data Bus bit 6. Data D6 access when CMD=0. Address A6 access when CMD=1.
42
SD5
I/O (PD)
Shared Data Bus bit 5. Data D5 access when CMD=0. Address A5 access when CMD=1.
43
SD4
I/O (PD)
Shared Data Bus bit 4. Data D4 access when CMD=0. Address A4 access when CMD=1.
44
SD3
I/O (PD)
Shared Data Bus bit 3. Data D3 access when CMD=0. Address A3 access when CMD=1.
45
SD2
I/O (PD)
Shared Data Bus bit 2. Data D2 access when CMD=0. Address A2 access when CMD=1.
46
VDD_IO
P
3.3V, 2.5V or 1.8V digital VDD input power supply for IO with well decoupling capacitors.
47
SD1
I/O (PD)
Shared Data Bus bit 1. Data D1 access when CMD=0. In 8-bit mode, this is address A1
access when CMD=1. In 16-bit mode, this is “Do Not Care” when CMD=1.
48
SD0
I/O (PD)
Shared Data Bus bit 0. Data D0 access when CMD=0. In 8-bit mode, this is address A0
access when CMD=1. In 16-bit mode, this is “Do Not Care” when CMD=1.
