H2A302G1656B
2Gb (16Mx8Banks×16) DDR2 SDRAM
The H2A302G1656B is a high speed Double Date Rate 2 (DDR2) Synchronous DRAM fabricated with ultra high performance CMOS process containing 2G bits which organized as 16Mbits x 8 banks by 16 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:
The 2Gb DDR2 devices operate with a single power supply: 1.8V ± 0.1V VDD and VDDQ.
Available package: TFBGA-84Ball.
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:
- posted CAS with additive latency,
- write latency = read latency -1,
- Off-Chip Driver (OCD) impedance adjustment and On Die Termination
- normal and weak strength data output driver.
The 2Gb DDR2 devices operate with a single power supply: 1.8V ± 0.1V VDD and VDDQ.
Available package: TFBGA-84Ball.
Features :
