V62C1161024L(L)
Ultra Low Power
64K x 16 CMOS SRAM
Features
Functional Description
• Ultra Low-power consumption
- Active: 30mA ICC at 70ns
- Stand-by: 5 µA (CMOS input/output)
1 µA (CMOS input/output, L version)
• 70/85/100/120 ns access time
• Equal access and cycle time
• Single +1.8V to 2.2V Power Supply
• Tri-state output
• Automatic power-down when deselected
The V62C1161024L is a Low Power CMOS Static RAM
organized as 65,536 words by 16 bits. Easy memory exp-
ansion is provided by an active LOW (CE) and (OE) pin.
This device has an automatic power-down mode feature
when deselected. Separate Byte Enable controls (BLE
and BHE) allow individual bytes to be accessed. BLE
controls the lower bits I/O1 - I/O8. BHE controls the
upper bits I/O9 - I/O16.
Writing to these devices is performed by taking Chip
Enable (CE) with Write Enable (WE) and Byte Enable
(BLE/BHE) LOW.
• Multiple center power and ground pins for
improved noise immunity
• Individual byte controls for both Read and
Write cycles
Reading from the device is performed by taking Chip
Enable (CE) with Output Enable (OE) and Byte Enable
(BLE/BHE) LOW while Write Enable (WE) is held
HIGH.
• Available in 44 pin TSOP (II) Package
