HYI25D256800C - 256-Mbit Double-Data-Rate SDRAM

Download the HYI25D256800C datasheet PDF. This datasheet also covers the HYI25D256160C variant, as both devices belong to the same 256-mbit double-data-rate sdram family and are provided as variant models within a single manufacturer datasheet.

Description

DQS, as well as to both edges of CK.

Read and write accesses to the DDR SDRAM are burst oriented; accesses start at a selected location and continue for a programmed number of locations in a programmed sequence.

Features

  • Auto Precharge option for each burst access Auto Refresh and Self Refresh Modes RAS-lockout supported tRAP = tRCD 7.8 µs Maximum Average Periodic Refresh Interval 2.5 V (SSTL_2 compatible) I/O VDDQ = 2.5 V ± 0.2 V (DDR200, DDR266, DDR333); VDDQ = 2.6 V ± 0.1 V (DDR400) VDD = 2.5 V ± 0.2 V (DDR200, DDR266, DDR333); VDD = 2.6 V ± 0.1 V (DDR400) Standard Temperature Range (0 °C - +70 °C) or.
