Advance Information
8Mb Ultra-Low Power Asynchronous CMOS SRAM
512K × 16 bit
Overview
Features
The N08L163WC2C 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. 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 N08L163WC2C 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
• 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
Dual Chip Enables (CE1 and CE2)
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 Available

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 internally
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.

Note:
1. Full device AC operation assumes a 100us ramp time from 0 to Vcc(min) and 200us wait time after Vcc stablization.
2. Full device operation requires linear Vcc ramp from VDR to Vcc(min) ≥ 100us or stable at Vcc(min) ≥ 100us.
