Pin Configuration[2, 3, 4]

FBGA

48TSOPI

44 TSOPII

Notes:

2. NC pins are not internally connected to the die.

3. DNU pins have to be left floating.

4. The BYTE pin in the TSOPI package has to be tied LOW to use the device as 1M x 8 SRAM. The 48-TSOPI package can also be used as a 512K × 16 SRAM

by tying the BYTE signal HIGH. For 512K x 16 functionality, please refer to the CY62157DV30 data sheet.
