Description

The VG3617161ET is CMOS Synchronous Dynamic RAM organized as 524,288-word X 16-bit X 2-bank. It is fabricated with an advanced submicron CMOS technology and designed to operate from a single 3.3V power supply. This SDRAM is delicately designed with performance concern for current high-speed application. Programmable CAS Latency and Burst Length make it possible to be used in widely various domains. It is packaged by using JEDEC standard pinouts and standard plastic 50-pin TSOP II.
