2Mb Ultra-Low Power Asynchronous Medical CMOS SRAM
256Kx8 bit
Overview
Features
The N02M0818L2A is an integrated memory
device intended for implanted life-support (Class 3)
medical applications. This device comprises a 2
Mbit Static Random Access Memory organized as
262,144 words by 8 bits. The device is designed
and fabricated using NanoAmp’s advanced CMOS
technology with reliability inhancements for
medical users. The base design is the same as
NanoAmp’s N02M0818L1A, which is intended for
non life-support (Class 1 and 2) medical
applications. The device operates with two chip
enable (CE1 and CE2) controls and output enable
(OE) to allow for easy memory expansion. The
N02M0818L2A is optimal for various applications
where low-power is critical such as implanted
pacemaker devices. The device can operate over a
very wide temperature range of -20oC to +60oC
and is available in die form as well as in JEDEC
standard packages compatible with other standard
256Kb x 8 SRAMs

1. When the device is in standby mode, control inputs (WE and OE), address inputs and data input/outputs are internally isolated
from any external influence and disabled from exerting any influence externally.
2. When WE is invoked, the OE input is internally disabled and has no effect on the circuit.

1. These limits are the expected operating conditions for this device. Only selected points within this range of conditions
are specifically tested and guaranteed.
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.
3. The chip is Disabled when CE1# is high or CE2 is low or UB# and LB# are high. The chip is Enabled when CE1# is
low and CE2 is high.
