Functional Description
The V62C3162048L 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.
