Description

The AS4C16M32SC-7TIN, AS4C32M16SC-7TIN and AS4C64M8SC-7TIN are four bank Synchronous DRAMs organized as 4 banks x 4MBit x32, 4 banks x 8Mbit x 16 and 4 banks x 16MBit x 8MBit x 8 respectively. These synchronous devices achieve high speed data transfer rates for CAS latencies by employing a chip architecture that prefetches multiple bits and then synchronizes the output data to a system clock.

The device is designed to comply with all industry standards set for synchronous DRAM products, both electrically and mechanically.All of the control, address, data input and output circuits are synchronized with the positive edge externally supplied clock

Operating the four memory banks in an interleave fashion allows random access operation to occur at a higher rate than is possible with standard DRAMs. A sequential and gapless data rate is possible depending on burst length, CAS latency and speed grade of the device.

Auto Refresh (CBR) and Self Refresh operation are supported. These devices operate with a single 3.3 V ± 0.3 V power supply. All 512-Mbit components are available in TSOPII–[86/54] packages.
