Benefits
of the DS1220AD 16k non-volatile SRAM over the M48Z12:
- Same 10% Vcc operation
- Pin-for-pin drop-in replacement for the M48Z12 in most cases
- Patented battery "freshness seal" extends shelf life prior to manufacturing
- 100ns, 120ns, 150ns, and 200ns access times
- A faster access time part may replace a slower access time part in most cases (i.e., a 100ns part can replace a 120ns part)
- 3V version in development
Benefits
of the M48Z12 ZEROPOWER® SRAM over the DS1220AD:
- 70ns, 150ns, and 200ns access times
