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.
