N02L83W2A/D

2Mb Ultra-Low Power Asynchronous CMOS SRAM

256K × 8 bit

Overview

The N02L83W2A is an integrated memory device

containing a 2 Mbit Static Random Access Memory

organized as 262,144 words by 8 bits. The device

is designed and fabricated using ON

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

N02L83W2A 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 -40oC to

+85oC and is available in JEDEC standard

packages compatible with other standard 256Kb x

8 SRAMs

Features

• Single Wide Power Supply Range

2.3 to 3.6 Volts

• Very low standby current

2.0µA at 3.0V (Typical)

• 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
