VCCQ = input voltage for core logic
VCCQL = independent input voltage for core logic
NC = not connected
VCCQH = independent input voltage for I/O lines
VCCA = voltage for external address lines
Unlisted pins are the same for both chips.
A pinout for the 196-pin PBGA package is included in the DSP56309 Technical Data Sheet. This package
will include the split power configuration described for the 144-pin TQFP package.
4 I/O Power Changes
The DSP56302 supports 5 V inputs for its peripherals. Complete requirements are described in the
DSP56302 Technical Data Sheet.
The DSP56309 supports 3.3 V inputs. Detailed voltage requirements are included in the DSP56309
Technical Data Sheet.
5 PLL Input Capacitor (CPCAP)
The process change results in a changed requirement for computing the size of CPCAP, the capacitor used
with the PCAP input. Table 1 lists the new formulas for computing the value of this input capacitor for the
DSP56309.
