illustrated here required only 10 gates; when very thin gates are needed, 100 or more can be set.
The gmZAN1 is pin-compatible with the gmB120 chip and is available in a 160-pin PQFP
The HC11, which is packaged in a small 128-pin PQFP
, operates at 3.3V and is priced at $15.00 each in 1,000/shipment quantities.
Heat that is to be dissipated by a metal heat spreader embedded in the mold compound underneath the die paddle in a PQFP
or similar package must first cross the layer of minimally conductive mold compound between the die paddle and heat spreader (Figure 1).
The socket accommodates IC packages such as the Texas Instruments Power Pad PQFP
, 0.4 mm pitch.
The TW2700 uses a 256-pin PQFP
package, will began sampling in Q2 2006, and will go mass production in Q3 2006.
