N16T1630C2B
16Mb Ultra-Low Power Asynchronous CMOS SRAM
1M x 16 bit
Overview
The N16T1630C2B is an integrated memory
device containing a low power 16 Mbit SRAM built
using a self-refresh DRAM array organized as
1,024,576 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 N16T1630C2B 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 packages
compatible with other standard 1Mb x 16 SRAMs.
