N01M0818L1A
1Mb Ultra-Low Power Asynchronous Medical CMOS SRAM
128Kx8 bit
Overview
Features
The N01M0818L1A is an integrated memory
device intended for non life-support (Class 1 or
2) medical applications. This device comprises a
1 Mbit Static Random Access Memory organized
as 131,072 words by 8 bits. The device is designed
and fabricated using NanoAmp’s advanced CMOS
technology with reliability inhancements for
• Single Wide Power Supply Range
1.4 to 2.3 Volts - STSOP package
• Dual Power Supply - Die Only
1.4 to 2.3 Volts - VCC
1.4 to 3.6 Volts - VCCQ
• Very low standby current
200nA maximum at 2.0V and 37 deg C
medical users. The base design is the same as
NanoAmp’s N01M0818L2A, which has further
reliability processing for life-support (Class 3)
medical applications. The device operates with two
chip enable (CE1 and CE2) controls and output
enable (OE) to allow for easy memory expansion.
The N01M0818L1A is optimal for various
• Very low operating current
1 mA at 2.0V and 1µs (Typical)
• Very low Page Mode operating current
0.5mA at 1.0V and 1µs (Typical)
• Simple memory control
Dual Chip Enables (CE1 and CE2)
Output Enable (OE) for memory expansion
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
• Low voltage data retention

o
Vcc = 1.2V
-40 C to +85 C and is available in JEDEC
standard packages compatible with other standard
256Kb x 8 SRAMs
• Automatic power down to standby mode
• Special Processing to reduce Soft Error Rate
