Family Silicon Errata and Data Sheet Clarification  
The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/  
X04 family devices that you have received conform  
functionally to the current Device Data Sheet  
(DS70318F), except for the anomalies described in this  
document.  
For example, to identify the silicon revision level  
using MPLAB IDE in conjunction with a hardware  
debugger:  
1. Using the appropriate interface, connect the  
device to the hardware debugger.  
The silicon issues discussed in the following pages are  
for silicon revisions with the Device and Revision IDs  
listed in Table 1. The silicon issues are summarized in  
Table 2.  
2. Open an MPLAB IDE project.  
3. Configure the MPLAB IDE project for the  
appropriate device and hardware debugger.  
4. Based on the version of MPLAB IDE you are  
using, do one of the following:  
The errata described in this document will be addressed  
in future revisions of the dsPIC33FJ06GS101/X02 and  
dsPIC33FJ16GSX02/X04 silicon.  
a) For MPLAB IDE 8, select Programmer >  
Reconnect.  
Note:  
This document summarizes all silicon  
errata issues from all revisions of silicon,  
previous as well as current. Only the  
issues indicated in the last column of  
Table 2 apply to the current silicon  
revision (A4).  
b) For MPLAB X IDE, select Window  
Dashboard and click the Refresh Debug  
Tool Status icon ( ).  
>
5. Depending on the development tool used, the  
part number and Device ID and Revision ID  
values appear in the Output window.  
Data Sheet clarifications and corrections start on page 17,  
following the discussion of silicon issues.  
Note:  
If you are unable to extract the silicon  
revision level, please contact your local  
Microchip sales office for assistance.  
The silicon revision level can be identified using the  
current version of MPLAB® IDE and Microchip’s  
programmers, debuggers and emulation tools, which  
are available at the Microchip corporate web site  
(www.microchip.com).  
The Device and Revision ID values for the various

Work around  
To synchronize the Independent PWM outputs

the Immediate Update Enable bit (IUE = 0), ensure  
that the three Least Significant bits of the period  
are zero, and that the duty cycle is between 8 ns  
and the period minus 0x8.  
• PWMxH is affected by Current-Limit source  
(FCLCON<CLSRC>) and the Current-Limit  
should be reset at the end of the primary local  
time base.  
• PWMxL is affected by Fault source  
(FCLCON<FLTSRC>) and the Fault should be  
reset at the end of the primary local time base.  
This work around will not work if the frequency of  
the PWM module is being updated on the fly.  
On silicon revisions affected by this erratum, the  
Current-Limit event works correctly for the PWMxH  
pin. However, the Fault event is reset by the  
secondary local time base although it is not used to  
generate the time base value. As a result, the Fault  
event on PWMxL pin may not work as expected.  
This erratum only applies to the cycle-by-cycle Fault

If PWM is in Complementary, Redundant or Push-  
Pull mode and (ITB = 1), set SPHASEx to have the

10. Module: Comparator  
If the slew rate of the Comparator input signal is  
lower than 198 mV/µs, the Comparator module  
generates erroneous triggers/interrupts.  
13. Module: Comparator  
The comparator interrupt should be generated on  
a rising edge of the comparator output. When  
using the inverted polarity setting for the analog  
comparator (CMPCONx<CMPPOL> = 1), the  
interrupt should be generated when the analog  
voltage at the comparator input falls below the  
programmable threshold determined by the  
CMPDAC register setting. However, with this  
setting the interrupts may be generated regardless  
of the state of the comparator.

3. Configure the STRIGx register to TRIGx + 0x8.  
4. Select the PWMx primary trigger as the ADC

If there are two I2C devices on the bus, one of  
them is acting as the Master receiver and the other  
as the Slave transmitter. If both devices are  
configured for 10-bit addressing mode, and have  
the same value in the A10 and A9 bits of their  
addresses, then when the Slave select address is  
sent from the Master, both the Master and Slave  
acknowledge it. When the Master sends out the  
read operation, both the Master and the Slave  
enter into Read mode and both of them transmit  
the data. The resultant data will be the ANDing of  
the two transmissions.  
If the PWM channel is configured for independent  
output mode and both channels are operating on  
the same time base, the phase difference between  
the two channels must be considered when setting  
the STRIGx register. This work around will not  
work for True Independent Time Base mode.  
With this work around, the PWMx secondary

During normal operation, if Leading-Edge  
Blanking (LEB) is triggered to start counting at a  
rising edge of PWM and the PWM module has a  
blanking time period less than the PWM assertive  
time (TON time), and the current-limit event occurs  
during the TON period and is still pending after the  
TON period is over, the current-limit event should  
be ignored during TON time, but should be  
recognized after the TON time is over.  
When using the PGEC3/PGED3 pins for device  
programming, the programming time may be  
slower as compared to other available PGECx/  
PGEDx pin pairs, because the Enhanced ICSP™  
programming algorithm cannot be executed on  
this pin pair.

The UART error interrupt may not occur, or may  
occur at an incorrect time, if multiple errors occur  
during a short period of time.

modes when accessing the first four bytes of an  
PSV page. This occurs only when using the  
following addressing modes:

Read the error flags in the UxSTA register  
whenever a byte is received to verify the error  
status. In most cases, these bits will be correct,

If the ADC module is in an enabled state when the  
device enters Sleep mode as a result of executing  
a PWRSAV #0instruction, the device power-down  
current (IPD) may exceed the specifications listed  
in the device data sheet. This may happen even if  
the ADC module is disabled by clearing the ADON  
bit prior to entering Sleep mode.  
Work arounds  
Work around 1:  
In order to remain within the IPD specifications  
listed in the device data sheet, the user software  
must completely disable the ADC module by  
setting the ADC Module Disable bit in the  
corresponding Peripheral Module Disable register  
(PMDx), prior to executing a PWRSAV  
#0  
instruction.  
Note:  
The ADC module must be reinitialized by  
the user application before resuming ADC  
operation.  
Work around 2:  
If the ADC module was previously initialized and  
enabled, before entering Sleep, execute the lines  
of code provided in Example 2.  
Note:  
Unlike Work around 1, the user  
application does not need to reinitialize  
the ADC module; however, it is necessary  
to re-enable the ADC module by setting  
the ADON bit after waking from Sleep.  
EXAMPLE 2:  
AD1CON1bits.ADON = 0;  
//Disable the ADC module  
__asm__ volatile ("REPEAT #50"); //Wait 50 TCY  
__asm__ volatile ("NOP");

2. Assign pin ownership to the GPIO module by  
32. Module: High-Speed PWM  
configuring IOCONx<PENH>  
=
0
and  
The PENH and PENL bits in the IOCONx register  
are used to assign ownership of the pins to either  
the PWM module or the GPIO module. The correct  
procedure to configure the PWM module is to  
assign pin ownership to the PWM module and then  
enabling it using the PTEN bit in the PTCON  
register.  
IOCONx<PENL> = 0.  
3. Specify the PWM override state to the desired  
safe state for the PWM pins using the  
OVRDAT<1:0> bit field in the IOCONx register.  
4. Override  
the  
PWM  
outputs  
by  
setting IOCONx<OVRENH> = 1 and  
IOCONx<OVRENL> = 1.  
If the PWM module is enabled using the above  
sequence, then a glitch may be observed on the  
PWM pins before actual switching of the PWM  
outputs begins. This glitch may cause momentary  
turn-on of power MOSFETs that are driven by the  
PWM pins and may cause damage to the  
application hardware.  
5. Enable the PWM module by setting  
PTCON<PTEN> = 1.  
6. Remove  
the  
PWM  
overrides  
by  
making IOCONx<OVRENH>  
=
0
and  
IOCONx<OVRENL> = 0.  
7. Ensure a delay of at least one full PWM cycle.  
8. Assign pin ownership to the PWM module  
Work around  
by setting IOCONx<PENH>  
=
1
and  
Follow the given sequence to avoid any glitches  
from appearing on the PWM outputs at the time of  
enabling.  
IOCONx<PENL> = 1.  
The code in Example 3 illustrates the use of this  
work around.  
1. Configure the respective PWM pins to digital  
inputs using the TRISx registers. This step will  
put the PWM pins in a high-impedance state.  
The PWM outputs must be maintained in a safe

33. Module: Reserved  
36. Module: SPI  
The issue in a previous version of the document  
was removed.  
When the SPI module is configured in Framed  
Master mode and the Frame Sync Pulse Edge  
Select bit (FRMDLY) is set to ‘1’, transmitting a  
word and then buffering another word in the SPIx-  
BUF register before the transmission has com-  
pleted, results in an incomplete transmission of the  
first data word. Only the first 15 bits from the first  
data word are transmitted, followed by the sync  
pulse and the complete second word.  
34. Module: PWM  
The High-Speed PWM provides a feature to  
update the PWM duty cycle at any time during the  
PWM period. The new duty cycle should take  
effect:  
• On the next PWM period when immediate duty  
cycle updates are disabled  
(PWMCONx<IUE> = 0).  
Work around  
Between the two back-to-back SPI operations,  
add a delay to ensure that the first word is fully  
transmitted before the second word is written to  
the SPIxBUF register, as shown in Example 4.  
• On the same PWM period when immediate  
duty cycle updates are enabled  
(PWMCONx<IUE> = 1).  
However, when the immediate duty cycle updates  
are disabled and the duty cycle update coincides  
with a PWM period roll-over, the PWM output may  
be corrupted and exhibit a 100% duty cycle for one  
PWM period. The new duty cycle value will take  
effect on the next PWM period.  
EXAMPLE 4:  
SPI1BUF = 0x0001;  
while (SPI1STATbits.SPITBF);  
asm("REPEAT #50");.  
asm("NOP");  
Work around  
Enable immediate duty cycle updates by  
configuring PWMCONx<IUE> = 1.  
// The number of NOPs depends on the SPI  
// clock prescalers  
SPI1BUF = 0x0002;

In JTAG mode, the TMS pin will not have an active  
pull-up as required by the JTAG specification.  
Instead, the pull-up function will be enabled on the  
TCK pin.  
37. Module: Comparator  
With the DAC output is disabled by clearing the  
DACOEN bit (CMPCONx<8>), output signal  
transitions occurring on the DACOUT pin can  
cause the comparator trigger voltage level to  
change. For example, if the UART1 Transmit  
(U1TX) signal is mapped to the same pin as  
DACOUT, UART data transmissions can cause  
the comparator to get triggered at different trigger  
levels than what is programmed through the  
CMPDACx register.  
Note:  
This issue is only present in the  
dsPIC33FJ06GS101 device.  
Work around  
An external pull-up resistor can be connected to  
the TMS pin to ensure that the signal does not  
enter a tri-state condition when in JTAG mode.  
There is no work around for the wrongly enabled  
pull-up function on the TCK pin.  
Work around  
When the comparator is enabled, do not use the  
DACOUT pin, either as a general purpose I/O pin  
or a peripheral output signal.

44. Module: PWM  
45. Module: PWM  
If the PWM is configured for Complimentary mode  
and the SWAP bit is enabled, the PWM outputs  
might operate as Redundant mode when the  
PHASE value is greater than the programmed  
dead-time (DTRx) value.  
The PWM current-limit operation allows the PWM  
module to set/reset the output signals when a  
specific current limit is detected with a minimum  
latency delay. When operating the PWM module in  
Complementary mode (PMOD = 0), positive dead  
time, and with Current-Limit Interrupt Enable  
(CLIEN = 1), a less than 8-ns pulse glitch on the  
complementary output may be present right after  
the current limit is detected. This glitch, if present,  
will occur prior to the implementation of the dead  
time.  
Work around  
Using true independent output mode with the  
independent Time Base mode bit (ITB) set to ‘0’,  
the PWM module can be configured to replicate  
the original complementary signal by properly  
setting up the phase (PHASEx, SPASEx) and the  
independent duty cycle (PDCx, SDCx).  
Work around  
In order to avoid the <8 ns glitch to be propagated  
into the MOSFET gate driver, a low-pass filter  
(e.g., resistor-capacitor network) should be  
implemented between the dsPIC® DSC PWM  
output pin and the gate driver IC input pin.

Note the following details of the code protection feature on Microchip devices:  
Microchip products meet the specification contained in their particular Microchip Data Sheet.  
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the  
intended manner and under normal conditions.  
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our  
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data  
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.  
Microchip is willing to work with the customer who is concerned about the integrity of their code.  
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not  
mean that we are guaranteeing the product as “unbreakable.”  
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our  
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts  
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.  
Information contained in this publication regarding device  
applications and the like is provided only for your convenience  
and may be superseded by updates. It is your responsibility to  
ensure that your application meets with your specifications.
