Texas Instruments Inc. has announced that it is sampling the SN74SSTU32864 25-bit configurable registered buffer, which is claimed to be the industry's first DDR-II logic register for evaluation in DDR-II memory module applications.

Based on the company's SN74SSTU32857 prototype device, the buffer can be configured as a 25-bit 1:1 pinout configuration or as a 14-bit 1:2 pinout allowing users to only work with a single part number for multiple DIMM configurations. Output edge-control circuitry is utilized in the device to minimize switching noise in unterminated lines to improve signal integrity.

The device also supports the DDR-II low power consumption mode where the chip-select inputs gate the data outputs from changing state and minimizes system power consumption.

Evaluation Samples for the SN74SSTU32864 available in a 96-ball LFBGA package.
