Winbond W664GG6RB-06

This product is a DDR4 SDRAM memory device in x16 configuration with a 96-ball VFBGA package. It supports high-speed data transfer and incorporates a wide range of advanced features to optimize system performance and reliability. The device includes a simplified state machine, fundamental read/write operation capabilities, and defines detailed reset and initialization procedures. Its operating modes are configurable via mode registers. Core features include burst length and order control, DLL enable/disable sequences, input clock frequency change adaptation, write leveling adjustment, and multiple temperature-controlled refresh modes. Additionally, it supports fine granularity refresh, multipurpose registers for DQ training, data mask, data bus inversion, ZQ calibration, DQ reference voltage training, per-DRAM addressability, command/address latency mode, CRC, command/address parity, gear-down mode, and programmable preamble and postamble. The device adheres to standard timing definitions for activate, precharge, and read operations.
