WINBOND华邦 W664GG6RB-06 DDR4 256*16 原装现货

 General Description
The W664GG6RB is a 4G bits DDR4 SDRAM, organized as 256Mb x 16 I/Os.  This device achieves high speed transfer rates up to 3200 MT/s (DDR4-3200) for various applications.  The W664GG6RB is sorted into the following speed grades: -06, -07,-08, 061, 071, 081, 06J, 07J and 08J. The-06 ,061 and 06J speed grades are compliant to the DDR4-3200 (22-22-22) specification (The 061 industrial grade which is guaranteed to support-40°Cs TCASE s 95°C, the 06J industrial plus grade which is guaranteed to support 40°Cs TCASE s 105°C). The-07 ,071 and 07J speed grades are compliant to the DDR4-2666 (19-19-19) specification (The 071 industrial grade which is guaranteed to support-40°Cs TCASE s 95°C, the 07J industrial plus grade which is guaranteed to support40°CsTCASE105°C)The-08, 081 and 08J speed grades are compliant to the DDR4-2400 (17-17-17) specification (The 081 industrial grade which is guaranteed to support -40°C s TCASE s 95°C, the 08J industrial plus grade which is guaranteed to support 40°Cs TCASE ≤ 105°C). The W664GG6RB is designed to comply with the following key DDR4 SDRAM features such as Temperature controlled Refresh, Low Power Auto Self Refresh, Fine Granularity Refresh, Data Bus Inversion, Command/Address Latency.  Command/Address Parity, Data bus Write CRC, Control Gear-Down, Programmable data strobe preamble, DQ VREF Training, Per DRAM Addressability, Connectivity Test, ZQ calibration, On Die Termination and Asynchronous Reset.  All of the control and address inputs are synchronized with a pair of externally supplied differential clocks.  Inputs are latched at the cross point of differential clocks (CK t rising and CK c falling).  All VOs are synchronized with a differential DQS_t-DQS-c pair in a source synchronous fashion.
