8Mb Ultra-Low Power Asynchronous CMOS SRAM
512K × 16 bit
Overview
The N08L163WC1C is an integrated memory
device containing a 8 Mbit Static Random Access
Memory organized as 524,288 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. 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
N08L163WC1C 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 -40oC to
+85oC and is available in JEDEC standard
packages compatible with other standard 512Kb x
16 SRAMs
Features
• Single Wide Power Supply Range
2.2 to 3.6 Volts
• Very low standby current
2.0µA at 3.0V (Typical)
• Very low operating current
1.5mA at 3.0V and 1µs(Typical)
• Simple memory control
Byte control for independent byte operation
Output Enable (OE) for memory expansion
• Low voltage data retention
Vcc = 1.5V
• Very fast output enable access time
25ns OE access time
• Automatic power down to standby mode
• TTL compatible three-state output driver
• Ultra Low Power Sort Avaliable

1. When UB and LB are in select mode (low), I/O0 - I/O15 are affected as shown. When LB only is in the select mode only I/O0
- I/O7 are affected as shown. When UB is in the select mode only I/O8 - I/O15 are affected as shown.
2. When the device is in standby mode, control inputs (WE, OE, UB, and LB), address inputs and data input/outputs are inter-
nally isolated from any external influence and disabled from exerting any influence externally.
3. When WE is invoked, the OE input is internally disabled and has no effect on the circuit.

1. Typical values are measured at Vcc=Vcc Typ., TA=25°C and not 100% tested.
2. This parameter is specified with the outputs disabled to avoid external loading effects. The user must add current required to drive
output capacitance expected in the actual system.
