PIN DESCRIPTIONS

A0 - A11

Address

Row Address : RA0 - RA11, Column Address : CA0 - CA7

Auto-precharge flag : A10

BA0,BA1

Bank Address

Selects bank to be activated during RAS activity

Selects bank to be read/written during CAS activity

DQ0 - DQ15

Data Input/Output

Multiplexed data input / output pin

CLK

Clock

The system clock input.All other inputs are registered to the SDRAM

on the rising edge of CLK

CKE

Clock Enable

Controls internal clock signal and when deactivated,the SDRAM will

be one of the states among power down,suspend or self refresh

CS

Chip Select

Enables or disables all inputs except CLK, CKE and DQM

RAS

Row Address Strobe

RAS,CAS and WE define the operation

CAS

Column Address Strobe

Refer function truth table for details

WE

Write Enable

LDQM,UDQM

Data Input/Output Mask

Controls output buffers in read mode and masks input data in write

mode

VDD/VSS

Power Supply/Ground

Power supply for internal circuits and input buffers

VDDQ/VSSQ

Data Output Power/Ground

Power supply for output buffers

NC
