Pin Groupings
The DSP56156 is available in a 112-pin Ceramic Quad Flat Pack (CQFP) and a 112-pin Plastic
Thin Quad Flat Pack (TQFP). The input and output signals are organized into the functional
groups indicated in Table 3. Figure 2 illustrates the chip’s pin functions.

NOTE:
OVERBARS are used throughout this document to indicate a signal which is at Ground voltage (typi-
cally a TTL logic low — VIL or VOL) when the function is logically true. These signals are, likewise, at
VCC voltage (typically a TTL logic high — VIH or VOH) when the function is logically false.
