AS4C8M16SA

128M - 8M x 16 bit Synchronous DRAM (SDRAM)

Confidential

Features

(Rev. 2.2, March 2014)

Overview

Fast access time from clock: 5/5.4 ns

Fast clock rate: 166/143 MHz

Fully synchronous operation

Internal pipelined architecture

2M word x 16-bit x 4-bank

Programmable Mode registers

- CAS Latency: 2, or 3

- Burst Length: 1, 2, 4, 8, or full page

- Burst Type: Sequential or Interleaved

- Burst stop function

The 128Mb SDRAM is a high-speed CMOS

synchronous DRAM containing 128 Mbits. It is

internally configured as 4 Banks of 2M word x 16

DRAM with a synchronous interface (all signals are

registered on the positive edge of the clock signal,

CLK). Read and write accesses to the SDRAM are

burst oriented; accesses start at a selected location

and continue for a programmed number of locations

in a programmed sequence. Accesses begin with

the registration of a BankActivate command which

is then followed by a Read or Write command.



Operating temperature range

- Commercial (0 ~ 70°C)

- Industrial (-40 ~ 85°C)

Auto Refresh and Self Refresh

4096 refresh cycles/64ms

CKE power down mode



The SDRAM provides for programmable Read

or Write burst lengths of 1, 2, 4, 8, or full page, with

a burst termination option. An auto precharge

function may be enabled to provide a self-timed row

precharge that is initiated at the end of the burst

sequence. The refresh functions, either Auto or Self

Refresh are easy to use.



Single +3.3V  0.3V power supply

Interface: LVTTL

54-pin 400 mil plastic TSOP II package

54-ball 8.0 x 8.0 x 1.2mm (max) FBGA package

By having a programmable mode register, the

system can choose the most suitable modes to

maximize its performance. These devices are well

suited for applications requiring high memory

bandwidth and particularly well suited to high

performance PC applications.

All parts ROHS Compliant
