Notes
2. Typical values are included for reference only and are not guaranteed or tested. Typical values are measured at V
CC
= V
CC(typ)
, T
A
= 25°C.
3. NC pins are not connected on the die.
4. The 44-TSOP II package has only one chip enable (CE) pin.
5. The BYTE pin in the 48-TSOP I package has to be tied HIGH to use the device as a 512K × 16 SRAM. The 48-TSOP I package can also be used as a 1M × 8
SRAM by tying the BYTE signal LOW. In the 1M x 8 configuration, Pin 45 is A19, while BHE, BLE and IO8 to IO14 pins are not used (DNU).
