Notes
CY62157EV30LL
1. NC pins are not connected on the die.
2. The 44-pin TSOP II package has only one chip enable (CE) pin.
3. The BYTE pin in the 48-pin TSOP I package must be tied HIGH to use the device as a 512 K × 16 SRAM. The 48-pin TSOP I package can also be used as a 1 M × 8
4. Typical values are included for reference only and are not guaranteed or tested. Typical values are measured at V
SRAM by tying the BYTE signal LOW. In the 1 M x 8 configuration, Pin 45 is A19, while BHE, BLE and I/O
