CL15 288-Pin DIMM Kit

This document describes ValueRAM s KVR21N15S8K2/8 is a
kit of two 512M x 64-bit (4GB) DDR4-2133 CL15 SDRAM
(Synchronous DRAM), 1Rx8, memory modules, based on eight
512M x 8-bit FBGA components. Total kit capacity is 8GB. The
SPD is programmed to JEDEC standard latency DDR4-2133
timing of 15-15-15 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
• Single-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
