A (CMOS input/output)

A (CMOS input/output, L version)

• 70/85/100/120 ns access time

• Equal access and cycle time

• Single +1.8V to2.2V Power Supply

• Tri-state output

• Automatic power-down when deselected

• Multiple center power and ground pins for

improved noise immunity

• Individual byte controls for both Read and

Write cycles

• Available in 44 pin TSOPII / 48-fpBGA / 48-

BGA

Functional Description

The V62C1162048L is a Low Power CMOS Static

RAM organized as 131,072 words by 16 bits. Easy

Memory expansion 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.

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.
