Functional Description

The V62C2161024L is a Low Power CMOS Static RAM
organized as 65,536 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
(BLE

) with Write Enable (WE) and Byte Enable

/BHE) LOW.

Reading from the device is performed by taking Chip
Enable (CE
(BLE

) with Output Enable (OE) and Byte Enable

/BHE) LOW while Write Enable (WE) is held

HIGH.
