# of Pins

Description

SIO1,SIO0

I/O

CMOSa

Serial input/output. Pins for reading from and writing to the control

registers using a serial access protocol. Also used for power man-

agement.

CMD

CMOSa

Command input. Pins used in conjunction with SIO0 and SIO1 for

reading from and writing to the control registers. Also used for

power management.

SCK

CMOSa

Serial clock input. Clock source used for reading from and writing to

the control registers

VDD

Supply voltage for the RDRAM core and interface logic.

VDDa

Supply voltage for the RDRAM analog circuitry.

VCMOS

Supply voltage for CMOS input/output pins.

GND

Ground reference for RDRAM core and interface.

GNDa

Ground reference for RDRAM analog circuitry.

DQA7..DQA0

I/O

RSLb

Data byte A. Eight pins which carry a byte of read or write data

between the Channel and the RDRAM.

CFM

RSLb

Clock from master. Interface clock used for receiving RSL signals

from the Channel. Positive polarity.

CFMN

RSLb

Clock from master. Interface clock used for receiving RSL signals

from the Channel. Negative polarity

VREF

Logic threshold reference voltage for RSL signals

CTMN

RSLb

Clock to master. Interface clock used for transmitting RSL signals

to the Channel. Negative polarity.

CTM

RSLb

Clock to master. Interface clock used for transmitting RSL signals

to the Channel. Positive polarity.

RQ7..RQ5 or

ROW2..ROW0

RSLb

Row access control. Three pins containing control and address

information for row accesses.

RQ4..RQ0 or

COL4..COL0

RSLb

Column access control. Five pins containing control and address

information for column accesses.

DQB7..

DQB0

I/O

RSLb

Data byte B. Eight pins which carry a byte of read or write data

between the Channel and the RDRAM.

No Connection

Total pin count per package

a. All CMOS signals are high-true; a high voltage is a logic one and a low voltage is logic zero.

b. All RSL signals are low-true; a low voltage is a logic one and a high voltage is logic zero.
