IS42/45SM/RM/VM16160E
4M x 16Bits x 4Banks Mobile Synchronous DRAM
Description
These IS42/45SM/RM/VM16160E are mobile 268,435,456 bits CMOS Synchronous DRAM organized as 4 banks of 4,194,304 words x 16
bits. These products are offering fully synchronous operation and are referenced to a positive edge of the clock. All inputs and outputs
are synchronized with the rising edge of the clock input. The data paths are internally pipelined to achieve high bandwidth. All input
and output voltage levels are compatible with LVCMOS.
Features
JEDEC standard 3.3V, 2.5V, 1.8V power supply.
Auto refresh and self refresh.
All pins are compatible with LVCMOS interface.
8K refresh cycle / 64ms.
Programmable Burst Length and Burst Type.
- 1, 2, 4, 8 or Full Page for Sequential Burst.
- 4 or 8 for Interleave Burst.
