H2A408G1666C

8Gb (64Mx8Banksx16) DDR3 SDRAM

The H2A408G1666C is a high speed Double Date Rate 3 (DDR3) low voltage Synchronous DRAM fabricated with ultra high performance CMOS process which organized as 64Mbits x 8 banks by 16 bits.
This synchronous device achieves high speed double-data-rate transfer rates of up to 1866 Mb/sec/pin (DDR3-1866) for general applications.

The chip is designed to comply with the following key DDR3 SDRAM features:
  • posted CAS with additive latency,
  • write latency = read latency -1,
  • On Die Termination,
  • programmable driver strength data,
  • seamless BL4 access with bank-grouping.
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 rising and /CK falling).
All I/Os are synchronized with a pair of bidirectional differential data strobes (DQS and /DQS) in a source synchronous fashion. The address bus is used to convey row, column and bank address information in a /RAS and /CAS multiplexing style.
Features :

  • Power Supply: VDD = VDDQ = 1.5V ±0.075V
  • All inputs and outputs are compatible with SSTL_15 interface.
  • Fully differential clock inputs (CK, /CK) operation.
  • Eight Banks
  • Posted CAS by programmable additive latency
  • Bust length: 4 with Burst Chop (BC) and 8.
  • CAS Write Latency (CWL): 5,6,7,8
  • CAS Latency (CL): 6, 7, 8, 9, 10, 11
  • Write Latency (WL) =Read Latency (RL) -1.
  • Bi-directional Differential Data Strobe (DQS).
  • Data inputs on DQS centers when write.
  • Data outputs on DQS, /DQS edges when read.
  • On chip DLL align DQ, DQS and /DQS transition with CK transition.
  • DM mask write data-in at the both rising and falling edges of the data strobe.
  • Sequential & Interleaved Burst type available both for 8 & 4 with BC.
  • Multi Purpose Register (MPR) for pre-defined pattern read out
  • On Die Termination (ODT) options: Synchronous ODT, Dynamic ODT, and Asynchronous ODT
  • Auto Refresh and Self Refresh
  • 8,192 Refresh Cycles / 64ms
  • Refresh Interval: 85°C ~ 95°C
  • RoHS Compliance
  • Driver Strength: RZQ/7, RZQ/6(RZQ=240Ω)
  • High Temperature Self-Refresh rate enable
  • ZQ calibration for DQ drive and ODT
  • RESET pin for initialization and reset function
