Requirements
All devices in the dsPIC33F/PIC24H family are dual volt-
age supply designs: one supply for the core and another
for the peripherals and I/O pins. A regulator is provided
on-chip to alleviate the need for two external voltage
supplies.
All of the dsPIC33F/PIC24H devices power their core
digital logic at a nominal 2.5V. To simplify system
design, all devices in the dsPIC33F/PIC24H Program-
ming Specification family incorporate an on-chip regu-
lator that allows the device to run its core logic from
V
DD
.
The regulator provides power to the core from the other
V
DD
pins. A low-ESR capacitor (such as tantalum) must
be connected to the V
DDCORE
pin (Figure 2-2). This
helps to maintain the stability of the regulator. The
specifications for core voltage and capacitance are
listed in
Section TABLE 8-1: 鈥淎C/DC Characteristics
and Timing Requirements鈥?
The program Flash memory on the dsPIC33F/PIC24H
has a specific write/erase requirement that must be
adhered to for proper device operation. The rule is that
any given word in memory must not be written without
first erasing the page in which it is located. Thus, the
easiest way to conform to this rule is to write all the data
in a programming block within one write cycle. The pro-
gramming methods specified in this document comply
with this requirement.
Note:
A program memory word can be pro-
grammed twice before an erase, but only
if (a) the same data is used in both pro-
gram operations or (b) bits containing 鈥?鈥?/div>
are set to 鈥?鈥?but no 鈥?鈥?is set to 鈥?鈥?
