View All Product from NXP USA Inc.The SSTUH32865 is a 1.8 V 28-bit high output drive 1:2 register specifically designed foruse on two rank by four (2R · 4) and similar high-density Double Data Rate 2 (DDR2)memory modules. It is similar in function to the JEDEC-standard 14-bit DDR2 register, butintegrates the functionality of the normally required two registers in a single package,thereby freeing up board real-estate and facilitating routing to accommodate high-densityDual In-line Memory Module (DIMM) designs.The SSTUH32865 also integrates a parity function, which accepts a parity bit from thememory controller, compares it with the data received on the D-inputs and indicateswhether a parity error has occurred on its open-drain PTYERR pin (active LOW).The SSTUH32865 is packaged in a 160-ball, 12 · 18 grid, 0.65 mm ball pitch, thin profilefine-pitch ball grid array (TFBGA) package, which—while requiring a minimum9 mm · 13 mm of board space—allows for adequate signal routing and escape usingconventional card technology.The SSTUH32865 is identical to SSTU32865 in function and performance, withhigher-drive outputs optimized to drive heavy load nets (such as stacked DRAMs) whilemaintaining speed and signal integrity.n 28-bit data register supporting DDR2n Higher output drive strength version of SSTU32865 optimized for high-capacitive loadnetsn Fully compliant to JEDEC standard JESD82-9n Supports 2 rank by 4 DIMM density by integrating equivalent functionality of twoJEDEC-standard DDR2 registers (that is, 2 · SSTU32864 or 2 · SSTU32866)n Parity checking function across 22 input data bitsn Parity out signaln Controlled output impedance drivers enable optimal signal integrity and speedn Exceeds JESD82-9 speed performance (1.8 ns max. single-bit switching propagationdelay, 2.0 ns max. mass-switching)n Supports up to 450 MHz clock frequency of operationn Optimized pinout for high-density DDR2 module designn Chip-selects minimize power consumption by gating data outputs from changing staten Supports Stub Series Terminated Logic SSTL_18 data inputsn Differential clock (CK and CK) inputs
