S-35390A是可以在超低消耗電流、寬工作電壓范圍內(nèi)工作的2線CMOS實時時鐘IC。工作電 壓為1.3 ~ 5.5 V、可適用于從主電源電壓到備用電池電壓的寬幅電源電壓。通過0.25 μA的計 時消耗電流和寬范圍的計時電源電壓，可大幅度地改善電池的持續(xù)時間。在使用備用電池工 作的系統(tǒng)中，內(nèi)置的自由寄存器可作為用戶備用存儲器來使用。在主電源切斷前存儲在寄存 器中的信息，可在電壓恢復(fù)后的任何時候讀出。 本產(chǎn)品因為內(nèi)置了時鐘校正功能，所以可以在很寬的范圍內(nèi)校正因振蕩電路的頻率偏差所導(dǎo) 致的時鐘數(shù)據(jù)的提前或滯后。通過此功能和溫度傳感器的結(jié)合，可根據(jù)溫度變化來對時鐘進 行校正，從而實現(xiàn)不受環(huán)境溫度影響的高精度的計時功能

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.
