PIC12F508/509 PIC12F508/509 Rev. B0 Silicon/Data Sheet Errata The PIC12F508/509 parts you have received conform functionally to the Device Data Sheet (DS41236E), except for the anomalies described below. All problems listed here will be addressed in future revisions of the PIC12F508/509 silicon. Where noted, problems apply to listed revision only. 1. Module: MPLAB® IDE, Revision 6.61 and Earlier MPLAB IDE 6.61 does not look for or set the Configuration Word in the hex file at the conventional logical location of 0xFFF. Work around: The CONFIG data must be assigned in two locations within the assembly code to ensure proper Configuration Word placement in the hex file. This is only required for MPLAB IDE version 6.61 and earlier. Fixed Code org 0xYYYY data _CP_OFF & _WDT_ON & etc. __CONFIG _CP_OFF & _WDT_ON & etc. 2. Module: PIC12F509 Debugging with ICD2 (PIC16F505-ICD Silicon) – Invalid FSR Power-Up Initialization The FSR on the PIC16F505-ICD debugger silicon initializes to an invalid state. When using the ICD to debug software with the PIC16F505-ICD, bit 5 in the FSR register must be manually cleared to ‘0’ prior to saving data in user RAM space. The power-up default is ‘1’, which causes the device to Access Bank 1. The power-up defaults are correct on the non-ICD version of the PIC12F509 devices. Work around: Add the following line of code to the top of your program; BCF FSR,5 ;set bank pointers to bank 0 This will have no effect on non-ICD devices, but will correct for the initialization errata on ICD devices. 3. Module: IPD, Power-Down Base Current .config code 0xYYYY On the PIC12F508/509 silicon, revisions earlier than A3, the power-down base current may remain higher than the specification for a short time when entering Sleep. data data _CP_OFF & _WDT_ON & etc. The following graph illustrates the device current upon entering Sleep: __CONFIG data _CP_OFF & _WDT_ON & etc. Re-locatable Code IDD Configuration Word Address Device YYYY PIC12F508 03FF PIC12F509 07FF Note: FIGURE 1: YYYY is the address of the Configuration Word for the part. IPD Time Device enters Sleep Device current reaches IPD The length of time between the device entering Sleep mode and the device current reaching IPD increases as both temperature and voltage decrease. Work around This issue is fixed in Revisions A3 and later. 2007-2016 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.
