1.8V, 25-bit (1:1) or 14-bit (1:2) JEDEC-Compliant

Data Register with Parity

CSR# inputs are HIGH. If either DCS# or CSR# input is LOW,

the Qn outputs will function normally. The RESET# input has

Features

• Operating frequency: DC to 500 MHz

• Supports DDRII SDRAM

priority over the DCS# and CSR# control and will force the

outputs LOW. If the DCS#-control functionality is not desired,

the CSR# input can be hardwired to ground, in which case the

set-up time requirement for DCS# would be the same as for

the other D data inputs.

• Two operations modes: 25 bit (1:1) and 14 bit (1:2)

• 1.8V operation

The device supports low-power standby operation. When the

reset input (RESET#) is LOW, the differential input receivers

are disabled, and undriven (floating) data, clock, and reference

voltage (VREF) inputs are allowed. In addition, when RESET#

is LOW, all registers are reset and all outputs are forced LOW.

The LVCMOS RESET# and Cn inputs must always be held at

a valid logic HIGH or LOW level. To ensure defined outputs

from the register before a stable clock has been supplied,

RESET# must be held in the LOW state during power-up.

• Fully JEDEC-compliant (JESD 82-10)

• 96-ball FBGA

Functional Description

All clock and data inputs are compatible with the JEDEC

standard for SSTL_18. The control inputs are LVCMOS. All

outputs are 1.8-V CMOS drivers that have been optimized to

drive the DDR-II DIMM load. The CY2SSTU32866 operates

from a differential clock (CK and CK#). Data are registered at

the crossing of CK going high, and CK# going LOW.

In the DDR-II RDIMM application, RESET# is specified to be

completely asynchronous with respect to CK and CK#.

Therefore, no timing relationship can be guaranteed between

the two. When entering reset, the register will be cleared and

the outputs will be driven low quickly, relative to the time to

disable the differential input receivers. However, when coming

out of reset, the register will become active quickly, relative to

the time to enable the differential input receivers.

The C0 input controls the pinout configuration of the 1:2 pinout

from A configuration (when LOW) to B configuration (when

HIGH). The C1 input controls the pinout configuration from

25-bit 1:1 (when LOW) to 14-bit 1:2 (when HIGH).

The device monitors both DCS# and CSR# inputs and will gate

the Qn outputs from changing states when both DCS# and
