N01L63W3A
1Mb Ultra-Low Power Asynchronous CMOS SRAM
64K × 16 bit
Features
Overview
• Single Wide Power Supply Range
2.3 to 3.6 Volts
The N01L63W3A is an integrated memory device
containing a 1 Mbit Static Random Access Memory
organized as 65,536 words by 16 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 a single chip
enable (CE) control 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. The N01L63W3A 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 64Kb x 16 SRAMs.

1. When UB and LB are in select mode (low), I/O0 - I/O15 are affected as shown. When LB only is in the select mode only I/O0 - I/O7
are affected as shown. When UB is in the select mode only I/O8 - I/O15 are affected as shown.
2. When the device is in standby mode, control inputs (WE, OE, UB, and LB), address inputs and data input/outputs are internally
isolated from any external influence and disabled from exerting any influence externally.
3. When WE is invoked, the OE input is internally disabled and has no effect on the circuit.

1. Typical values are measured at Vcc=Vcc Typ., TA=25°C and are not 100% tested.
2. This parameter is specified with the outputs disabled to avoid external loading effects. The user must add current required to drive
output capacitance expected in the actual system.
3. This device assumes a standby mode if the chip is disabled (CE high). In order to achieve low standby current all inputs must be
within 0.2 volts of either VCC or VSS

Note: Page mode operation is a method of addressing the SRAM to save operating current. The internal
organization of the SRAM is optimized to allow this unique operating mode to be used as a valuable power
saving feature.
The only thing that needs to be done is to address the SRAM in a manner that the internal page is left open
and 16-bit words of data are read from the open page. By treating addresses A0-A3 as the least significant
bits and addressing the 16 words within the open page, power is reduced to the page mode value which is
considerably lower than standard operating currents for low power SRAMs.
