N64T1618C1B

Advance Information

64Mb Ultra-Low Power Asynchronous CMOS PSRAM

4M × 16 Bits

Overview

Features

The N64T1618C1B is an integrated memory

device containing a 64 Mbit Pseudo Static Random

Access Memory using a self-refresh DRAM array

organized as 4,194,304 words by 16 bits. It is

designed to be compatible in operation and

interface to standard 6T SRAMS. The device is

designed for low standby and operating current

and includes a power-down feature to

automatically enter standby mode. The device

includes a ZZ input for deep sleep as well as

several other power saving modes: Partial Array

Self Refresh mode where data is retained in a

portion of the array and Temperature

Compensated Refresh. Both these modes reduce

standby current drain. The N64T1618C1B can be

operated in a standard asynchronous mode and

data can also be read in a 4-word page mode for

fast access times. The die has separate power

rails, VccQ and VssQ for the I/O to be run from a

separate power supply from the device core.
