Notes
2. NC pins are not connected internally to the die and are typically used for address expansion to a higher-density device. Refer to the respective datasheets for pin
configuration.
3. Tie the BYTE pin in the 48-pin TSOP I package to V
CC
to use the device as a 1 M × 16 SRAM. The 48-pin TSOP I package can also be used as a 2 M × 8 SRAM by
tying the BYTE signal to V
SS
. In the 2 M × 8 configuration, Pin 45 is the extra address line A20, while BHE, BLE, and I/O
8
to I/O
14
pins are not used and can be left
floating.
