HYS72T64301HP-3.7-A - 240-Pin Registered DDR2 SDRAM Modules

Download the HYS72T64301HP-3.7-A datasheet PDF. This datasheet also covers the HYS72T64301HP-3S-A variant, as both devices belong to the same 240-pin registered ddr2 sdram modules family and are provided as variant models within a single manufacturer datasheet.

General Description

capacitive loading to the system bus, but adds one cycle to the SDRAM timing.

Decoupling capacitors are mounted on the PCB board.

The DIMMs feature serial presence detect based on a serial E2PROM device using the 2-pin I2C protocol.

Key Features

  • Programmable CAS Latencies (3, 4 and 5), Burst Length (4 & 8) and Burst Type.
  • Auto Refresh (CBR) and Self Refresh.
  • Average Refresh Period 7.8 µs at a TCASE lower than 85°C, 3.9 µs between 85 °C and 95 °C.
  • Programmable self refresh rate via EMRS2 setting.
  • All inputs and outputs SSTL_18 compatible.
  • Off-Chip Driver Impedance Adjustment (OCD) and On-Die Termination (ODT).
  • Serial Presence Detect with E2PROM.
  • Based on standard re.
