registered buffer with parity for DDR2 RDIMM applications
Rev. 01 — 13 May 2005
Product data sheet
1. General description
The SSTUH32866 is a 1.8 V configurable register specifically designed for use on DDR2
memory modules requiring a parity checking function. It is defined in accordance with the
JEDEC JESD82-7 standard for the SSTU32864 registered buffer, while adding the parity
checking function in a compatible pinout. The JEDEC standard for SSTUH32866 is
pending publication. The register is configurable (using configuration pins C0 and C1) to
two topologies: 25-bit 1 : 1 or 14-bit 1 : 2, and in the latter configuration can be designated
as Register A or Register B on the DIMM.
The SSTUH32866 accepts a parity bit from the memory controller on its parity bit
(PAR_IN) input, compares it with the data received on the DIMM-independent D-inputs
and indicates whether a parity error has occurred on its open-drain QERR pin
(active LOW). The convention is even parity, that is, valid parity is defined as an even
number of ones across the DIMM-independent data inputs combined with the parity input
bit.
The SSTUH32866 is packaged in a 96-ball, 6 × 16 grid, 0.8 mm ball pitch LFBGA
package (13.5 mm × 5.5 mm).
The SSTUH32866 is identical to SSTU32866 in function and performance, with
higher-drive outputs optimized to drive heavy load nets (for example, stacked DRAMs)
while maintaining speed and signal integrity.

7. Functional description
The SSTUH32866 is a 25-bit 1 : 1 or 14-bit 1 : 2 configurable registered buffer with parity,
designed for 1.7 V to 1.9 V VDD operation.
All clock and data inputs are compatible with the JEDEC standard for SSTL_18. The
control and reset (RESET) inputs are LVCMOS. All data outputs are 1.8 V CMOS drivers
that have been optimized to drive the DDR2 DIMM load, and meet SSTL_18
specifications. The error (QERR) output is 1.8 V open-drain driver.
The SSTUH32866 operates from a differential clock (CK and CK). Data are registered at
the crossing of CK going HIGH, and CK going LOW.
The C0 input controls the pinout configuration for 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 SSTUH32866 accepts a parity bit from the memory controller on its parity bit
(PAR_IN) input, compares it with the data received on the DIMM-independent D-inputs
and indicates whether a parity error has occurred on its open-drain QERR pin
(active LOW). The convention is even parity, that is, valid parity is defined as an even
number of ones across the DIMM-independent data inputs combined with the parity input
bit.
When used as a single device, the C0 and C1 inputs are tied LOW. In this configuration,
parity is checked on the PAR_IN input which arrives one cycle after the input data to which
it applies. The partial-parity-out (PPO) and QERR signals are produced three cycles after
the corresponding data inputs.
When used in pairs, the C0 input of the first register is tied LOW and the C0 input of the
second register is tied HIGH. The C1 input of both registers are tied HIGH. Parity, which
arrives one cycle after the data input to which it applies, is checked on the PAR_IN input of
the first device. The PPO and QERR signals are produced on the second device three
clock cycles after the corresponding data inputs. The PPO output of the first register is

1.8 V high-drive DDR2 configurable registered buffer with parity
cascaded to the PAR_IN of the second register. The QERR output of the first register is
left floating and the valid error information is latched on the QERR output of the second
register.
If an error occurs and the QERR output is driven LOW, it stays latched LOW for two clock
cycles or until RESET is driven LOW. The DIMM-dependent signals (DCKE, DCS, DODT,
and CSR) are not included in the parity check computation.
The device supports low-power standby operation. When 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 input must always be held at a valid
logic HIGH or LOW level.
The device also supports low-power active operation by monitoring both system chip
select (DCS and CSR) inputs and will gate the Qn and PPO outputs from changing states
when both DCS and CSR inputs are HIGH. If either DCS or CSR input is LOW, the Qn
and PPO outputs will function normally. The RESET input has priority over the DCS and
CSR control and when driven LOW will force the Qn and PPO outputs LOW, and the
QERR output HIGH. If the DCS control functionality is not desired, then the CSR input can
be hard-wired to ground, in which case, the setup time requirement for DCS would be the
same as for the other Dn data inputs. To control the low-power mode with DCS only, then
the CSR input should be pulled up to VDD through a pull-up resistor.
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.
In the DDR2 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 Qn 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. As long as the data inputs are LOW, and the clock is stable
during the time from the LOW-to-HIGH transition of RESET until the input receivers are
fully enabled, the design of the SSTUH32866 must ensure that the outputs will remain
LOW, thus ensuring no glitches on the output.

13. Soldering
13.1 Introduction to soldering surface mount packages
This text gives a very brief insight to a complex technology. A more in-depth account of
soldering ICs can be found in our Data Handbook IC26; Integrated Circuit Packages
(document order number 9398 652 90011).
There is no soldering method that is ideal for all surface mount IC packages. Wave
soldering can still be used for certain surface mount ICs, but it is not suitable for fine pitch
SMDs. In these situations reflow soldering is recommended.
13.2 Reflow soldering
Reflow soldering requires solder paste (a suspension of fine solder particles, flux and
binding agent) to be applied to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement. Driven by legislation and
environmental forces the worldwide use of lead-free solder pastes is increasing.
Several methods exist for reflowing; for example, convection or convection/infrared
heating in a conveyor type oven. Throughput times (preheating, soldering and cooling)
vary between 100 seconds and 200 seconds depending on heating method.
Typical reflow peak temperatures range from 215 °C to 270 °C depending on solder paste
material. The top-surface temperature of the packages should preferably be kept:
• below 225 °C (SnPb process) or below 245 °C (Pb-free process)
– for all BGA, HTSSON..T and SSOP..T packages
– for packages with a thickness ≥ 2.5 mm
– for packages with a thickness < 2.5 mm and a volume ≥ 350 mm3 so called
thick/large packages.
• below 240 °C (SnPb process) or below 260 °C (Pb-free process) for packages with a
thickness < 2.5 mm and a volume < 350 mm3 so called small/thin packages.
Moisture sensitivity precautions, as indicated on packing, must be respected at all times.
13.3 Wave soldering
Conventional single wave soldering is not recommended for surface mount devices
(SMDs) or printed-circuit boards with a high component density, as solder bridging and
non-wetting can present major problems.
To overcome these problems the double-wave soldering method was specifically
developed.
If wave soldering is used the following conditions must be observed for optimal results:
• Use a double-wave soldering method comprising a turbulent wave with high upward
pressure followed by a smooth laminar wave.
• For packages with leads on two sides and a pitch (e):
– larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be
parallel to the transport direction of the printed-circuit board;

– smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the
transport direction of the printed-circuit board.
The footprint must incorporate solder thieves at the downstream end.
• For packages with leads on four sides, the footprint must be placed at a 45° angle to
the transport direction of the printed-circuit board. The footprint must incorporate
solder thieves downstream and at the side corners.
During placement and before soldering, the package must be fixed with a droplet of
adhesive. The adhesive can be applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the adhesive is cured.
Typical dwell time of the leads in the wave ranges from 3 seconds to 4 seconds at 250 °C
or 265 °C, depending on solder material applied, SnPb or Pb-free respectively.
A mildly-activated flux will eliminate the need for removal of corrosive residues in most
applications.
13.4 Manual soldering
Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage
(24 V or less) soldering iron applied to the flat part of the lead. Contact time must be
limited to 10 seconds at up to 300 °C.
When using a dedicated tool, all other leads can be soldered in one operation within
2 seconds to 5 seconds between 270 °C and 320 °C.

For more detailed information on the BGA packages refer to the (LF)BGA Application Note (AN01026);
order a copy from your Philips Semiconductors sales office.

All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the
maximum temperature (with respect to time) and body size of the package, there is a risk that internal or
external package cracks may occur due to vaporization of the moisture in them (the so called popcorn
effect). For details, refer to the Drypack information in the Data Handbook IC26; Integrated Circuit
Packages; Section: Packing Methods.
[3]
These transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no
account be processed through more than one soldering cycle or subjected to infrared reflow soldering with
peak temperature exceeding 217 °C ± 10 °C measured in the atmosphere of the reflow oven. The package
body peak temperature must be kept as low as possible.

These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the
solder cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink
on the top side, the solder might be deposited on the heatsink surface.
[5]
If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave
direction. The package footprint must incorporate solder thieves downstream and at the side corners.
[6]
Wave soldering is suitable for LQFP, QFP and TQFP packages with a pitch (e) larger than 0.8 mm; it is
definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.
[7]
Wave soldering is suitable for SSOP, TSSOP, VSO and VSSOP packages with a pitch (e) equal to or larger
than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
[8]
Image sensor packages in principle should not be soldered. They are mounted in sockets or delivered
pre-mounted on flex foil. However, the image sensor package can be mounted by the client on a flex foil by
using a hot bar soldering process. The appropriate soldering profile can be provided on request.
[9]
Hot bar soldering or manual soldering is suitable for PMFP packages.
