N02L163WC2A
2Mb Ultra-Low Power Asynchronous CMOS SRAM
128Kx16 bit
Overview
Features
The N02L163WC2A is an integrated memory
device containing a 2 Mbit Static Random Access
Memory organized as 131,072 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
• Single Wide Power Supply Range
2.3 to 3.6 Volts
• Very low standby current
2.0µA at 3.0V (Typical)
• Very low operating current
2.0mA at 3.0V and 1µs (Typical)
NanoAmp’s N02L1618N1A, which is processed to
operate at lower 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 N02L163WC2A 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
• Very low Page Mode operating current
0.8mA at 3.0V and 1µs (Typical)
• Simple memory control
Dual Chip Enables (CE1 and CE2)
Byte control for independent byte operation
Output Enable (OE) for memory expansion
• Low voltage data retention
Vcc = 1.8V
• Very fast output enable access time
30ns OE access time
temperature range of -40oC to +85oC and is
available in JEDEC standard packages compatible
with other standard 128Kb x 16 SRAMs
• Automatic power down to standby mode
• TTL compatible three-state output driver
• Compact space saving BGA package avail-
