LOW POWER 3V CMOS SRAM
1 MEG (64K x 16-BIT)
ADVANCE
INFORMATION
IDT71L016
FEATURES:
• 64K x 16 Organization
• Wide Operating Voltage Range: 2.7V to 3.6V
• Speed Grades: 70ns, 100ns
• Low Operating Power: 45mA (max)
• Low Standby Power: 5µA (max)
• Low-Voltage Data Retention: 1.5V (min)
• Available in a 44-pin TSOP package
DESCRIPTION:
The IDT71L016 is a 1,048,576-bit very low-power Static
RAM organized as 64K x 16. It is fabricated using IDT’s high-
reliability CMOS technology. This state-of-the-art technology,
combined with innovative circuit design techniques, provides
a cost-effective solution for low-power memory needs. It uses
a 6-transistor memory cell.
All input and output signals of the IDT71L016 are LVTTL-
compatible and operation is from a single extended-range
3.3V supply. This extended supply range makes the device
ideally suited for unregulated battery-powered applications.
Fully static asynchronous circuitry is used, requiring no clocks
or refresh for operation.
The IDT71L016 is packaged in a JEDEC standard 44-pin
TSOP Type II.
