H2A302G0856B

2Gb (32Mx8Banks×8) DDR2 SDRAM

The H2A302G0856B is a high speed Double Date Rate 2 (DDR2) Synchronous DRAM fabricated with ultra high performance CMOS process containing 2G bits which organized as 32Mbits x 8 banks by 8 bits.
This synchronous device achieves high speed double-data-rate transfer rates of up to 1066 Mb/sec/pin (DDR2-1066) for general applications.
The chip is designed to comply with the following key DDR2 SDRAM features:
  1. posted CAS with additive latency,
  2. write latency = read latency -1,
  3. Off-Chip Driver (OCD) impedance adjustment and On Die Termination
  4. normal and weak strength data output driver.

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 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. The 2Gb DDR2 devices operate with a single power supply: 1.8V ± 0.1V VDD and VDDQ.
Available package: TFBGA-60Ball.
Features :

  • JEDEC Standard VDD/VDDQ = 1.8V±0.1V.
  • All inputs and outputs are compatible with SSTL_18 interface.
  • Fullydifferential clock inputs (CK, /CK) operation.
  • EightBanks
  • Posted CAS
  • Bust length: 4 and 8.
  • Programmable CAS Latency (CL): 5, 6
  • Programmable Additive Latency (AL):0, 1, 2, 3, 4, 5
  • Write Latency (WL) =Read Latency (RL) -1.
  • Read Latency (RL) = Programmable Additive Latency (AL) + CAS Latency (CL)
  • Bi-directional DifferentialData 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.
  • Off-Chip Driver (OCD) Impedance Adjustment
  • On Die Termination (ODT)
  • Auto Refresh and Self Refresh
  • 8,192 Refresh Cycles / 64ms
  • RoHS Compliance
  • Partial Array Self-Refresh (PASR)
  • High Temperature Self-Refresh rate enable
