Power Distribution and I/O Ring Implementation
56F8346 Technical Data
Preliminary
155
Consider all device loads as well as parasitic capacitance due to PCB traces when calculating
capacitance. This is especially critical in systems with higher capacitive loads that could create
higher transient currents in the V
DD
and V
SS
circuits.
Take special care to minimize noise levels on the V
REF
, V
DDA
and V
SSA
pins
Designs that utilize the TRST pin for JTAG port or EOnCE module functionality (such as
development or debugging systems) should allow a means to assert TRST whenever RESET is
asserted, as well as a means to assert TRST independently of RESET. Designs that do not require
debugging functionality, such as consumer products, should tie these pins together.
Because the Flash memory is programmed through the JTAG/EOnCE port, the designer should
provide an interface to this port to allow in-circuit Flash programming
12.3 Power Distribution and I/O Ring Implementation
Figure 12-1
illustrates the general power control incorporated in the 56F8346. This chip contains
an internal regulator which cannot be disabled. The regulator takes regulated 3.3V power from the
V
DD_IO
pins and provides 2.5V to the internal logic of the chip. This means the entire part is
powered from the 3.3V supply.
Notes:
Flash, RAM and internal logic are powered from the core regulator output
V
PP
1 and V
PP
2 are not connected in the customer system
All circuitry, analog
and
digital, shares a common V
SS
bus
