N02M0818L2A
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
• Single Wide Power Supply Range
1.3 to 2.3 Volts
• Very low standby current
200nA typical at 2.1V and 37 deg C
• Very low operating current
1 mA at 2.0V and 1µs (Typical)
medical users. The base design is the same as
NanoAmp’s N02M0818L1A, which is intended for
non life-support (Class 1 and 2) medical
• Very low Page Mode operating current
0.5mA at 1.0V and 1µs (Typical)
• Simple memory control
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
Dual Chip Enables (CE1 and CE2)
Output Enable (OE) for memory expansion
• Low voltage data retention
Vcc = 1.0V
• Automatic power down to standby mode
• TTL compatible three-state output driver
