Product Summary

The K4T1G164QF-BCE7 is a 512Mb G-die DDR2 SDRAM. It is organized as a 32Mbit x 4 I/Os x 4banks or 16Mbit x 8 I/Os x 4banks or 8Mbit x 16 I/Os x 4 banks device. The K4T1G164QF-BCE7 achieves high speed doubledata-rate transfer rates of up to 800Mb/sec/pin (DDR2-800) for general applications. The chip is designed to comply with the following key DDR2 SDRAM features such as posted CAS with additive latency, write latency = read latency -1, Off-Chip Driver(OCD) impedance adjustment and On Die Termination. The K4T1G164QF-BCE7 operates with a single 1.8V ± 0.1V power supply and 1.8V ± 0.1V VDDQ. It is available in 60ball FBGAs(x8) and in 84ball FBGAs(x16).
