N04M1618L1A
4Mb Ultra-Low Power Asynchronous Medical CMOS SRAM
256Kx16 bit
Overview
The N04M1618L1A is an integrated memory
device
intended for non life-support (Class 1 or
2) medical applications.
This device is a 4
megabit memory organized as 262,144 words by
16 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
N04M1618L2A, 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. Byte
controls (UB and LB) allow the upper and lower
bytes to be accessed independently and can also
be used to deselect the device. This device 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 -40
o
C to +85
o
C and is
available in a JEDEC standard BGA package
Features
• Dual Power Supply for lowest power
1.4 to 2.3 Volts - VCC
1.4 to 3.6 Volts - VCCQ
• Very low standby current
400nA at 2.0V and 37 deg C Maximum
• Very low operating current
0.7mA at 1.8V and 1µs (Typical)
• Low Page Mode operating current
0.5mA at 1.8V 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 = 1.2V
• Automatic power down to standby mode
• Special Processing to reduce Soft Error Rate
(SER)
• Space saving BGA package available
