PIN FUNCTION DESCRIPTION

Name

System cock

Input Function

CLK

Active on the positive going edge to sample all inputs.

Disables or enables device operation by masking or enabling all inputs except

CLK, CKE and DQM

Chip select

Masks system clock to freeze operation from the next clock cycle.

CKE should be enabled at least one cycle prior to new command.

Disable input buffers for power down in standby.

CKE

Clock enable

Row/column addresses are multiplexed on the same pins.

Row address : RA0 ~ RA12, Column address : CA0 ~ CA8

A0 ~ A12

BA0 ~ BA1

RAS

Address

Selects bank to be activated during row address latch time.

Selects bank for read/write during column address latch time.

Bank select address

Row address strobe

Column address strobe

Write enable

Latches row addresses on the positive going edge of the CLK with RAS low.

Enables row access & precharge.

Latches column addresses on the positive going edge of the CLK with CAS low.

Enables column access.

CAS

Enables write operation and row precharge.

Latches data in starting from CAS, WE active.

Makes data output Hi-Z, tSHZ after the clock and masks the output.

Blocks data input when L(U)DQM active.

L(U)DQM

Data input/output mask

DQ0 ~ 15

VDD/VSS

Data input/output

Data inputs/outputs are multiplexed on the same pins.

Power and ground for the input buffers and the core logic.

Power supply/ground

Isolated power supply and ground for the output buffers to provide improved noise

immunity.

VDDQ/VSSQ

Data output power/ground

No connection

/reserved for future use

N.C/RFU

This pin is recommended to be left No Connection on the device.
