Pin Assignments and Descriptions

Pin Descriptions

Symbol

A0–A12

Type

Input

Description

Address inputs:

Provide the row address for ACTIVE commands, and the

column address and auto precharge bit (A10) for READ/WRITE commands, to

select one location out of the memory array in the respective device bank. A10

sampled during a PRECHARGE command determines whether the PRECHARGE

applies to one device bank (A10 LOW, device bank selected by BA0 and BA1)

or all device banks (A10 HIGH). The address inputs also provide the op-code

during a MODE REGISTER SET command. BA0 and BA1 define which mode

register (mode register or extended mode register) is loaded during the LOAD

MODE REGISTER command.

Bank address:

BA0 and BA1 define the device bank to which an ACTIVE,

READ, WRITE, or PRECHARGE command is being applied.

Clock:

CK and CK# are differential clock inputs. All control, command, and

address input signals are sampled on the crossing of the positive edge of CK

and the negative edge of CK#. Output data (DQ and DQS) is referenced to the

crossings of CK and CK#.

Clock enable:

CKE enables (registered HIGH) and CKE disables (registered

LOW) the internal clock, input buffers, and output drivers.

Input data mask:

DM is an input mask signal for write data. Input data is

masked when DM is sampled HIGH, along with that input data, during a write

access. DM is sampled on both edges of DQS. Although DM pins are input-only,

the DM loading is designed to match that of DQ and DQS pins.

Command inputs:

RAS#, CAS#, and WE# (along with S#) define the command

being entered.

Chip selects:

S# enables (registered LOW) and disables (registered HIGH) the

command decoder.

Presence-detect address inputs:

These pins are used to configure the SPD

EEPROM address range on the I

2

C bus.

Serial clock for SPD EEPROM:

SCL is used to synchronize the presence-detect

data transfer to and from the module.

Data input/output:

Data bus.

Data strobe:

Output with read data. Edge-aligned with read data. Input with

write data. Center-aligned with write data. Used to capture data.

Serial data:

SDA is a bidirectional pin used to transfer addresses and data into

and out of the presence-detect portion of the module.

Power supply:

+2.5V ±0.2V (-40B: +2.6V ±0.1V).

Serial EEPROM power supply:

+2.3V to +3.6V.
