Name
A0-A19 Address Input
BS616LV1613
Function
These 20 address inputs select one of the 1,048,576 x 16-bit words in the RAM.
CE1 Chip Enable 1 Input
CE2 Chip Enable 2 Input
WE Write Enable Input
OE Output Enable Input
LB and UB Data Byte Control Input
CE1 is active LOW and CE2 is active HIGH. Both chip enables must be active when
data read from or write to the device. If either chip enable is not active, the device is
deselected and is in a standby power mode. The DQ pins will be in the high
impedance state when the device is deselected.
The write enable input is active LOW and controls read and write operations. With the
chip selected, when WE is HIGH and OE is LOW, output data will be present on the
DQ pins; when WE is LOW, the data present on the DQ pins will be written into the
selected memory location.
The output enable input is active LOW. If the output enable is active while the chip is
selected and the write enable is inactive, data will be present on the DQ pins and they
will be enabled. The DQ pins will be in the high impedance state when OE is inactive.
Lower byte and upper byte data input/output control pins.
D0 - D15 Data Input/Output Ports These 16 bi-directional ports are used to read data from or write data into the RAM.
