    Abstract: Disclosed is a programmable impedance control circuit, comprising a voltage divider, the voltage divider comprising an MOS array supplied with a first voltage and an external resistance having an external impedance equal to N times said external resistance. The voltage divider outputs a second voltage. A reference voltage generator is provided for generating a third voltage corresponding to N/(N+M) times said first voltage as a reference voltage for said second voltage, and wherein M times internal impedance is used for N times external impedance (N=M or N<>M).

    Abstract: PURPOSE: A lead frame having a pre-plated part is provided to prevent degradation of bonding strength between the lead frame and molding resin and thereby to improve reliability of a package using the lead frame. CONSTITUTION: The lead frame(200) includes a plurality of leads(130), which are arranged in a pair of rows. Each of the leads(130) has an inner lead(110) to be connected with a bonding pad of a semiconductor chip, and an outer lead(120) extended from the inner lead(110) and also fastened to a side rail(140). The lead frame(200) further has a plating layer(132) previously formed on the leads(130) before forming the package to enhance the bonding strength between the leads(130) and the molding resin. In particular, the lead frame(200) has the pre-plated part(D) where the plating layer(132) is formed, and a non-plated part(C) where the plating layer(132) is not formed. When the inner and outer leads(110,120) are distinguished from each other by a boundary line(A), the pre-plated part(D) and the non-plated part(C) are separated by an imaginary dividing line(B) which is located inward from the boundary line(A).
