• 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:
