Notes
CY62157EV30LL
1. Typical values are included for reference only and are not guaranteed or tested. Typical values are measured at V
2. NC pins are not connected on the die.
3. The 44-TSOP II package has only one chip enable (CE) pin.
4. The BYTE pin in the 48-TSOP I package must 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 I/O8 to I/O14 pins are not used (NC).
