HY27US08121B-TPCB

The HY27US08121B-TPCB is an unbuffered 184-pin DDR DIMM manufactured by SK HYNIX. It offers a capacity of 256MB, organized as 32Mx64, utilizing eight 32Mx8 DDR SDRAM components in TSOP II packages.

This memory module operates with a power supply voltage of 2.3V to 2.7V (2.5V typical) for both VDD and VDDQ. It features an SSTL_2 interface and supports fully differential clock operations with frequencies of 100MHz, 125MHz, and 133MHz. The device supports programmable CAS Latency of 2 or 2.5, and programmable Burst Lengths of 2, 4, or 8 in both sequential and interleave modes.

Designed for ease of interchange and addition, the HY27US08121B-TPCB is suitable for systems requiring high-speed memory. It includes auto refresh and self-refresh capabilities, with 8192 refresh cycles required every 64ms. The module is housed in a standard 184-pin DIMM form factor and uses a TSOP package.

Key electrical characteristics include a 2.5V power supply and compatibility with SSTL_2 interface standards. The module supports various clock speeds and burst lengths, making it adaptable to different system requirements. Its unbuffered design and standard DIMM form factor facilitate integration into existing hardware.
