Notes:For pin connections, see individual data sheets for M48T201Y/V and M68Z512/W at www.st. com.

The chip enable access time of the external SRAM will be the combination of the chip enable access for the SRAM itself, plus the chip

enable propagation delay tEPD for the M48T201Y/V.

1. For 5V, M48T513Y (M48T201Y + M68Z512). For 3.3V, M48T513V (M48T201V + M68Z512W).

2. SNAPHAT® Top ordered separately.

3. RSTIN input is the same input as RSTIN2 of M48T201Y/V.
