1024k NV SRAM，带有隐含时钟

具有隐含时钟的DS1248 1024k NV SRAM为全静态非易失RAM (按照8位、128k字排列)，内置实时时钟。DS1248自带锂电池及控制电路，控制电路连续监视VCC是否超出容差范围，一旦超出容差，锂电池便自动切换至供电状态，写保护将无条件使能、以防存储器和实时时钟数据被破坏。 \n• 实时时钟(RTC)保持跟踪百分之一秒、秒、分、时、星期、日、月和年 \n• 128k x 8 NV SRAM可直接替代易失静态RAM或EEPROM \n• 内置锂电池维持日历运行及保存RAM数据 \n• 时钟功能对RAM操作完全透明 \n• 月和年决定每个月的天数，有效期至2100年 \n• 10%工作范围 \n• 工作温度范围：0°C至+70°C \n• 无外部电源时可保存数据10年以上 \n• 第一次上电前，锂电池与电路断开、维持保鲜状态 \n• 提供DIP模块 \n• 标准32引脚JEDEC引脚排列 \n• 提供无引线封装 \n• PowerCap模板 \n• 表面贴装可;
