| dsPIC33FJ12GP201/202 dsPIC33FJ12GP201/202 Rev. A2 Silicon Errata The dsPIC33FJ12GP201/202 (Rev. A2) devices you received were found to conform to the specifications and functionality described in the following documents: * DS70264 - "dsPIC33FJ12GP201/202 Data Sheet" * DS70157 - "dsPIC30F/33F Programmer's Reference Manual" The exceptions to the specifications in the documents listed above are described in this section. The specific devices for which these exceptions are described are listed below: * dsPIC33FJ12GP201 * DSPIC33FJ12GP202 dsPIC33FJ12GP201/202 Rev. A2 silicon is identified by performing a "Reset and Connect" operation to the device using MPLAB(R) ICD 2 or MPLAB REAL ICETM in-circuit emulator, with MPLAB IDE v7.60 or later. The output window will show a successful connection to the device specified in Configure>Select Device. The errata described in this document will be addressed in future revisions of silicon. 6. 4. Silicon Errata Summary The following list summarizes the errata described in further detail through the remainder of this document: 1. 2. JTAG Programming JTAG programming does not work. UART UART receptions may be corrupted if the Baud Rate Generator (BRG) is set up for 4x mode. 3. UART The auto-baud feature may not calculate the correct baud rate when the BRG is set up for 4x mode. UART With the auto-baud feature selected, the Sync Break character (0x55) may be loaded into the FIFO as data. 5. UART The auto-baud feature measures baud rate inaccurately for certain baud rate and clock speed combinations. Traps and Idle Mode If a clock failure occurs when the device is in Idle mode, the oscillator failure trap does not vector to the Trap Service Routine. The following sections describe the errata and work around to these errata, where they may apply. (c) 2007 Microchip Technology Inc. DS80327A-page 1 dsPIC33FJ12GP201/202 1. Module: JTAG Programming JTAG programming does not work. Work around None. 5. Module: UART The auto-baud feature may miscalculate for certain baud rate and clock speed combinations, resulting in a BRG value that is greater than or less than the expected value by 1. This may result in reception or transmission failures. Work around Test the auto-baud rate at various clock speed and baud rate combinations that would be used in an application. If an inaccurate BRG value is generated, manually correct the baud rate in user software. 2. Module: UART UART receptions may be corrupted if the Baud Rate Generator is set up for 4x mode (BRGH = 1). Work around Use the 16x baud rate option (BRGH = 0) and adjust the baud rate accordingly. 3. Module: UART The auto-baud feature may not calculate the correct baud rate when the High Baud Rate Enable bit, BRGH, is set. With the BRGH bit set, the baud rate calculation used is the same as BRG = 0. Work around If the auto-baud feature is needed, use the Low Baud Rate mode by clearing the BRGH bit. 6. Module: Traps and Idle Mode If a clock failure occurs when the device is in Idle mode, the oscillator failure trap does not vector to the Trap Service Routine. Instead, the device will simply wake-up from Idle mode and continue code execution if the Fail-Safe Clock Monitor (FSCM) is enabled. Work around Whenever the device wakes up from Idle (assuming the FSCM is enabled) the user software should check the state of the OSCFAIL bit (INTCON1<1>) to determine whether a clock failure occurred, and then perform the appropriate clock switch operation. 4. Module: UART With the auto-baud feature selected, the Sync Break character (0x55) may be loaded into the FIFO as data. Work around To prevent the Sync Break character from being loaded into the FIFO, load the UxBRG register with either 0x0000 or 0xFFFF prior to enabling the auto-baud feature (ABAUD = 1).

REVISION HISTORY (c) 2007 Microchip Technology Inc. DS80327A-page 3 dsPIC33FJ12GP201/202 NOTES: DS80327A-page 4 (c) 2007 Microchip Technology Inc. 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.
