The ICS9131 offers a tiny footprint solution for generating a selectable CPU clock from a 32.768 kHz crystal. The device allows a variety of microprocessors to be clocked by changing the state of address lines FS0, FS1, and FS2. The ICS9131 i s the ideal solution for replacing high speed oscillators and for reducing clock speeds to save power in computers. The device provides smooth, glitch-free frequency transitions so that the CPU can continue to operate during slow down or speed up. The rate of frequency change makes the ICS9131 compatible with all 386DX, 386SX, 486DX, 486DXZ, 486SX and PentiumTM microprocessors. |
