S-35390A是可以在超低消耗电流、宽工作电压范围内工作的2线CMOS实时时钟IC。工作电 压为1.3 ~ 5.5 V、可适用于从主电源电压到备用电池电压的宽幅电源电压。通过0.25 μA的计 时消耗电流和宽范围的计时电源电压，可大幅度地改善电池的持续时间。在使用备用电池工 作的系统中，内置的自由寄存器可作为用户备用存储器来使用。在主电源切断前存储在寄存 器中的信息，可在电压恢复后的任何时候读出。 本产品因为内置了时钟校正功能，所以可以在很宽的范围内校正因振荡电路的频率偏差所导 致的时钟数据的提前或滞后。通过此功能和温度传感器的结合，可根据温度变化来对时钟进 行校正，从而实现不受环境温度影响的高精度的计时功能

Top module name : SHIFTER (File name : SHIFTER.v) 2. Input pins: SHIFT [3:0], IN [15:0], SIGN, RIGHT. 3. Output pins: OUT [15:0]. 4. Input signals generated from test pattern are latched in one cycle and are synchronized at clock rising edge. 5. The SHIFT signal describes the shift number. The shift range is 0 to 15. 6. When the signal RIGHT is high, it shifts input data to right. On the other hand, it shifts input data to left. 7. When the signal SIGN is high, the input data is a signed number and it shifts with sign extension. However, the input data is an unsigned number if the signal SIGN is low. 8. You can only use following gates in Table I and need to include the delay information (Tplh, Tphl) in your design.
