SSTUP32866 1.8 V 25-bit 1 : 1 or 14-bit 1 : 2 configurable registered buffer with parity and programmable output for DDR2-800 RDIMMs Rev. 02 — 14 September 2006 Product data sheet 1. General description The SSTUP32866 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 standard for the SSTUA32866 and SSTUB32866 registered buffers. 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. It offers added features over the JEDEC standard register in that it can be configured for high or normal output drive strength, as well as for operation to 667 MT/s or 800 MT/s, simply by tying two input pins HIGH or LOW as needed. The SSTUP32866 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 SSTUP32866 is packaged in a 96-ball, 6 × 16 grid, 0.8 mm ball pitch LFBGA package (13.5 mm × 5.5 mm). 2.

Functional description The SSTUP32866 is a 25-bit 1 : 1 or 14-bit 1 : 2 configurable registered buffer with parity, designed for 1.7 V to 2.0 V VDD operation. Additionally, the SSTUP32866 can be programmed to deliver either normal or high output drive, and either 600 MT/s or 800 MT/s speeds. Two programming pins, SELAB and SELDR, allow the user to respectively select speed and drive strength options by tying these pins either LOW or HIGH on the DIMM. The truth table for these options is shown in Table 6. 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 SSTUP32866 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 SSTUP32866 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. SSTUP32866_2 Product data sheet © Koninklijke Philips Electronics N.V. 2006. All rights reserved. Rev. 02 — 14 September 2006 8 of 31 SSTUP32866 Philips Semiconductors 1.8 V DDR2-667/800 programmable registered buffer with parity 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 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 SSTUP32866 must ensure that the outputs will remain LOW, thus ensuring no glitches on the output.

Soldering 13.1 Introduction to soldering surface mount packages 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 temperatures range from 215 °C to 260 °C depending on solder paste material. The peak top-surface temperature of the packages should be kept below: Table 14. SnPb eutectic process - package peak reflow temperatures (from J-STD-020C July 2004) Package thickness Volume mm3 < 350 Volume mm3 ≥ 350 < 2.5 mm 240 °C + 0/−5 °C 225 °C + 0/−5 °C ≥ 2.5 mm 225 °C + 0/−5 °C 225 °C + 0/−5 °C Table 15.

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): SSTUP32866_2 Product data sheet © Koninklijke Philips Electronics N.V. 2006.

Rev. 02 — 14 September 2006 26 of 31 SSTUP32866 Philips Semiconductors 1.8 V DDR2-667/800 programmable registered buffer with parity – 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. 13.5 Package related soldering information Table 16.

[2] 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).

The package body peak temperature must be kept as low as possible. [4] 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. 14. Abbreviations Table 17.
