PRELIMINARY DATA SHEET
6. Application Circuit
Note: Pin numbers refer to the PLCC68 package, numbers in brackets refer to the PSDIP64 package.
Application Note:
All ground pins should be connected to one low-resistive
ground plane.
All supply pins should be connected separately with
short and low-resistive lines to the power supply.
Decoupling capacitors from DVSUP to DVSS, AVSUP to
AVSS, and AHVSUP to AHVSS are recommended as
close as possible to these pins. Decoupling of DVSUP
and DVSS is most important. We recommend using
ResetQ
(from CCU,
see
section.3.3.)

more than one capacitor. By choosing different values,
the frequency range of active decoupling can be ex-
tended. In our application boards we use: 220 pF,
470 pF, 1.5 nF, and 10 F. The capacitor with lowest val-
ue should be placed nearest to the DVSUP and DVSS
pins.
The ASG1 pin should be connected as closely as pos-
sible to the MSP to ground. If it is lead with the SC1 input-
lines as shielding line, it should NOT be conneted to
ground at the SCART connector.
