Popis produktu

ValueRAM s KVR32N22D8/32 is a 4G x 64-bit (32GB) DDR4-3200 CL22 SDRAM (Synchronous DRAM), 2Rx8, memory module, based on sixteen 2G x 8-bit FBGA components. The SPD is programmed to JEDEC standard latency DDR4-3200 timing of 22-22-22 at 1.2V. Each 288-pin DIMM uses gold contact fingers. The electrical and mechanical specifications are as follows:
• Power Supply: VDD = 1.2V Typical • VDDQ = 1.2V Typical • VPP = 2.5V Typical • VDDSPD = 2.2V to 3.6V • Nominal and dynamic on-die termination (ODT) for data, strobe, and mask signals • Low-power auto self refresh (LPASR) • Data bus inversion (DBI) for data bus • On-die VREFDQ generation and calibration • Dual-rank • On-board I2 serial presence-detect (SPD) EEPROM • 16 internal banks; 4 groups of 4 banks each • Fixed burst chop (BC) of 4 and burst length (BL) of 8 via the mode register set (MRS) • Selectable BC4 or BL8 on-the-fly (OTF) • Fly-by topology • Terminated control command and address bus • PCB: Height 1.23” (31.25mm) • RoHS Compliant and Halogen-Free
