The H2A402G1666O is a high speed Double Date Rate 3 (DDR3) Synchronous DRAM fabricated with ultra high performance CMOS process containing 1G 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 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.
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. The 2Gb DDR3 devices operates with a single power supply: 1.5V ± 0.075V VDD andVDDQ. Available package: WBGA-96Ball (with 0.8mm - 0.8mm ball pitch)
