1. General description
2. Features and benefits
3. Applications
The SSTUB32866 is a 1.8 V configurable register specifically designed for use on DDR2
memory modules requiring a parity checking function. 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 SSTUB32866 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 SSTUB32866 is packaged in a 96-ball, 6 × 16 grid, 0.8 mm ball pitch LFBGA package
(13.5 mm × 5.5 mm).
