APPENDIX A: DIFFERENCES
The dsPIC33FJXXXMCX06/X08/X10 Motor Control
Family devices marked “PS” have some key differ-
ences from the final production devices (devices not
marked “PS”). The major differences are listed in this
appendix. In addition, there are minor differences in
several SFR names, bits and Reset states, which are
described in Section 3.0 “Memory Organization”
and the corresponding peripheral sections.
A.1
The Prototype Sample devices have a suffix “PS” in
their names, as marked on the device package. This
distinguishes them from Engineering Sample devices
(which are suffixed “ES”) and final production devices
(that have neither a “PS” nor an “ES” suffix on the
device package marking).
Prototype samples are available only for a subset of the
final production devices. Please refer to the device
tables in this data sheet for a listing of all devices.
A.2
The total RAM size, including the size of the dual ported
DMA RAM, is different between each “PS” device and
the corresponding final production device. For exam-
ple, the final production devices have 2 Kbytes DMA
RAM, whereas the “PS” devices have 1 Kbyte DMA
RAM. Please refer to the device tables in this data
sheet
dsPIC33FJXXXMCX06/X08/X10 Motor Control Family
device.
A.3
The final production devices have four more interrupt
sources (vectors) than the “PS” devices do. Also, two
of the interrupt vectors are associated with slightly dif-
ferent events from the corresponding interrupts in the
“PS” devices. Please refer to Section 6.0 “Interrupt
Controller” for more details.
A.4
Both “PS” and final production devices can perform
Direct Memory Access (DMA) data transfers.
In addition to all of the features supported by the DMA
controller in the “PS” devices, the DMA controller in the
final production devices also supports the Peripheral
Indirect Addressing mode. Please refer to Section 7.0
“Direct Memory Access (DMA)” for a description of
this feature.

The default values of the PLL postscaler and feedback
divisor bits are different between the “PS” devices and
final production devices. Please refer to Section 8.0
“Oscillator Configuration” for the register definitions
and Reset states.
A.6
The dsPIC33FJXXXMCX06/X08/X10 Motor Control
Family devices marked “PS” have up to two CAN mod-
ules. The functionality and register layout of these mod-
ules are identical to those of dsPIC30F devices, and
are described in Section 20.0 “Enhanced CAN Mod-
ule” of this data sheet. These modules do not provide
DMA support.
The final production devices have up to two Enhanced
CAN (ECAN™ technology) modules. These modules
have significantly more features than the CAN mod-
ules, mainly in the form of an increased number of
available buffers, filters and masks, as well as DMA
support.
A.7
Both “PS” and final production devices contain up to
two ADC modules.
The “PS” devices have a 16-word deep ADC result
buffer.
The final production devices have enhanced DMA sup-
port in the form of additional DMA RAM and Peripheral
Indirect Addressing. This renders the 16-word ADC
buffer redundant. Hence, the buffer has been replaced
by a single ADC Result register.
A.8
The final production devices are offered in the following
TQFP packages:
• 64-pin TQFP 10x10x1 mm
• 80-pin TQFP 12x12x1 mm
• 100-pin TQFP 12x12x1 mm
• 100-pin TQFP 14x14x1 mm
The “PS” devices are offered in the following TQFP
packages:
• 64-pin TQFP 10x10x1 mm
• 80-pin TQFP 12x12x1 mm
• 100-pin TQFP 14x14x1 mm
