N02M083WL1A
2Mb Ultra-Low Power Asynchronous Medical CMOS SRAM
256Kx8 bit
Overview
Features
The N02M083WL1A is an integrated memory
device intended for non life-support (Class 1 or 2)
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
• Single Wide Power Supply Range
2.3 to 3.6 Volts
• Low standby current
3µA maximum at 3.6V
• Very low operating current
2 mA at 3.6V and 1Mhz (Typical)
medical users. The base design is the same as
NanoAmp’s N02M0818L2A, 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 N02M083WL1A is optimal for various
• Very low Page Mode operating current
0.5mA at 3.6V and 1Mhz (Typical)
• Simple memory control
Dual Chip Enables (CE1 and CE2)
Output Enable (OE) for memory expansion
• Low voltage data retention
Vcc = 1.8V
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
• Automatic power down to standby mode
• TTL compatible three-state output driver
