N08T1630CxB
8Mb Ultra-Low Power Asynchronous CMOS SRAM
512Kx16 bit
Overview
The N08T1630CxB is an integrated memory
device containing a low power 8 Mbit SRAM built
using a self-refresh DRAM array organized as
512,288 words by 16 bits. It is designed to be
identical 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 operates with two chip enable (CE1 and
CE2) controls and output enable (OE) to allow for
easy memory expansion. Byte controls (UB and
LB) allow the upper and lower bytes to be
accessed independently and can also be used to
deselect the device. The N08T1630CxB is optimal
for various applications where low-power is critical
such as battery backup and hand-held devices.
The device can operate over a very wide
temperature range of -40
o
C to +85
o
C and is
available in JEDEC standard BGA and TSOP2
packages compatible with other standard 512Kb x
16 SRAMs.
