Описание

The DS1248Y-70+ is a 1024K NV SRAM with Phantom clock in 32 pin EDIP package. The 1024K NV SRAM with phantom clock is a fully static, non-volatile RAM (organized as 128K words by 8 bits) with a built-in real time clock. The DS1248 has a self-contained lithium energy source and control circuitry which constantly monitors VCC for an out of tolerance condition. When such a condition occurs, the lithium energy source is automatically switched on and writes protection is unconditionally enabled to prevent garbled data in both the memory and real time clock. The phantom clock provides timekeeping information for hundredths of seconds, minutes, hours, days, date, month and years.

• Supply voltage range is 4.5V to 5.5V
• Operating temperature range from 0°C to 70°C
• 128K x 8 NV SRAM directly replaces volatile static RAM or EEPROM
• Read cycle time and access time is 70ns
• Embedded lithium energy cell maintains calendar operation and retains RAM data
• Watch function is transparent to RAM operation
• Automatic leap year compensation valid up to 2100
• Over 10 years of data retention in the absence of power
• Lithium energy source is disconnected to retain freshness until power is applied for the first time
• UL recognized
