1. General description
2. Features
The SSTUA32S865 is a 1.8 V 28-bit 1 : 2 register specifically designed for use on two
rank by four (2R
modules. It is similar in function to the JEDEC-standard 14-bit DDR2 register, but
integrates the functionality of the normally required two registers in a single package,
thereby freeing up board real-estate and facilitating routing to accommodate high-density
Dual In-line Memory Module (DIMM) designs.
The SSTUA32S865 also integrates a parity function, which accepts a parity bit from the
memory controller, compares it with the data received on the D-inputs and indicates
whether a parity error has occurred on its open-drain PTYERR pin (active LOW).
The SSTUA32S865 is packaged in a 160-ball, 12
fine-pitch ball grid array (TFBGA) package, which (while requiring a minimum
9 mm
conventional card technology.
