M48Z18：5 V, 64 Kbit (8 Kb x 8) ZEROPOWER® SRAM

The M48Z08/18 ZEROPOWER^®RAM is an 8 K x 8 non-volatile static RAM which is pin and function compatible with the DS1225.

The monolithic chip provides a highly integrated battery-backed memory solution.

The M48Z08/18 is a non-volatile pin and function equivalent to any JEDEC standard 8 K x 8 SRAM. It also easily fits into many ROM, EPROM, and EEPROM sockets, providing the non-volatility of PROMs without any requirement for special write timing or limitations on the number of writes that can be performed.

The 28-pin, 600 mil DIP CAPHAT^™houses the M48Z08/18 silicon with a long-life lithium button cell in a single package.

Key Features

• Integrated, ultra low power SRAM and power-fail control circuit
• Unlimited WRITE cycles
• READ cycle time equals WRITE cycle time
• Automatic power-fail chip deselect and WRITE protection
• WRITE protect voltages (VPFD = power-fail deselect voltage):
  • M48Z08: VCC = 4.75 to 5.5 V; 4.5 V ≤ VPFD ≤ 4.75 V
  • M48Z18: VCC = 4.5 to 5.5 V; 4.2 V ≤ VPFD ≤ 4.5 V
• Self-contained battery in the CAPHAT™ DIP package
• Pin and function compatible with JEDEC standard 8 K x 8 SRAMs
• RoHS compliant
  • Lead-free second level interconnect
