DESCRIPTION

· The SSTUM32866 is a 1.8 V configurable register designed for DDR2 memory modules with parity checking, compliant with JEDEC standards.

· Configurable via pins C0 and C1 to 25-bit 1:1 or 14-bit 1:2 topologies, with the latter allowing designation as Register A or B on DIMMs.

· Features a parity bit input (PAR_IN) for comparison with DIMM-independent data inputs, signaling parity errors via the QERR pin.

· Packaged in a 96-ball LFBGA format, measuring 13.5 mm × 5.5 mm with a 0.8 mm ball pitch.

FEATURES

· Supports DDR2 up to 800 MT/s in registered DIMM applications.

· Configurable to 25-bit 1:1 or 14-bit 1:2 modes.

· High output drive with controlled impedance for optimal signal integrity.

· Operates up to 550 MHz and supports SSTL_18 data inputs.

· Includes differential clock inputs and supports LVCMOS switching levels.

· Single 1.8 V supply operation (1.7 V to 2.0 V).

APPLICATIONS

· Ideal for high-density DDR2 module designs requiring parity checking.

· Suitable for systems where signal integrity and speed are critical.

· Used in environments that benefit from reduced power consumption through chip-selects.
