N02L83W2A  
2Mb Ultra-Low Power Asynchronous CMOS SRAM  
256K × 8 bit  
Overview  
containing a 2 Mbit Static Random Access Memory  
organized as 262,144 words by 8 bits. The device  
is designed and fabricated using ON  
Features  
2.3 to 3.6 Volts  
• Very low standby current  
2.0µA at 3.0V (Typical)  
The N02L83W2A is an integrated memory device  
• Single Wide Power Supply Range  
Semiconductor’s advanced CMOS technology to  
provide both high-speed performance and ultra-low  
power. The device operates with two chip enable  
(CE1 and CE2) controls and output enable (OE) to  
allow for easy memory expansion. The  
• Very low operating current  
2.0mA at 3.0V and 1µs (Typical)  
• Very low Page Mode operating current  
0.8mA at 3.0V and 1µs (Typical)  
• Simple memory control  
Dual Chip Enables (CE1 and CE2)  
Output Enable (OE) for memory expansion  
• Low voltage data retention  
Vcc = 1.8V  
• Very fast output enable access time  
30ns OE access time  
• Automatic power down to standby mode  
• TTL compatible three-state output driver  
N02L83W2A is optimal for various applications  
where low-power is critical such as battery backup  
and hand-held devices. The device can operate  
o
over a very wide temperature range of -40 C to  
o
+85 C and is available in JEDEC standard  
packages compatible with other standard 256Kb x  
8 SRAMs
