Opis produktu
M48Z08/18 - ZEROPOWER® RAM is an 8K x8 non-volatile static RAM which is pin and func-tional compatible with the DS1225. The monolithicchip is available in two special packages to providea highly integrated battery backed-up memory so-lution.
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
- Power Dissipation Pd: 1W
- Output Current Io: 20mA
- VCC = –0.3 to 7 V
- operating temperature–40 to 85 °C
