N04L1618C2A
4Mb Ultra-Low Power Asynchronous CMOS SRAM
256Kx16 bit
Overview
The N04L1618C2A is an integrated memory
device containing a 4 Mbit Static Random Access
Memory organized as 262,144 words by 16 bits.
The device is designed and fabricated using
NanoAmp’s advanced CMOS technology to
provide both high-speed performance and ultra-low
power. The base design is the same as
NanoAmp’s N04L163WC1A, which is processed to
operate at higher voltages. 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 N04L1618C2A 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 packages compatible
with other standard 256Kb x 16 SRAMs
