Type
Term
Description
VDD
Pna
VDD pins for internal logic.
VDD_A
Pna
VDD pins for analog circuits. Pay critical attention to bypassing this supply.
VDD_IO
Pna
VDD pins for I/O buffers.
VDD_DRAM
Pna
VDD pins for internal DRAM.
VREF
I
na
Reference voltage defines the trip point for all input buffers, except SCLK, RST_IN,
POR_IN, IRQ3–0, FLAG3–0, DMAR3–0, ID2–0, CONTROLIMP1–0, LxDATO3–0P/N,
LxCLKOUTP/N, LxDATI3–0P/N, LxCLKINP/N, TCK, TDI, TMS, and TRST. VREF can be
connected to a power supply or set by a voltage divider circuit as shown in Figure 6.
SCLK_VREF
I
na
System Clock Reference. Connect this pin to a reference voltage as shown in Figure 7.
VSS
Gna
Ground pins.
NC
nc
No Connect. Do not connect these pins to anything (not to any supply, signal, or each
other). These pins are reserved and must be left unconnected.
I = input; A = asynchronous; O = output; OD = open-drain output; T = three-state; P = power supply; G = ground; pd = internal pull-down
