Benefits
of the DS1220AB 16k nonvolatile SRAM over the M48Z02:
- Same 5% Vcc operation
- Virtually identical replacement for the M48Z02
- 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 M48Z02 ZEROPOWER® SRAM over the DS1220AB:
- 70ns, 150ns, and 200ns access times
- 0.030" shorter package (same footprint)
