Data Sheet Clarifications
The foll owing ty pographic corrections and clar ification s
are to be note d fo r the latest ve rsi on of th e device da ta
sheet (DS41268D). Changes described in Modules 1,
2, 3, and 4 below apply to the PIC12F510 on ly and n ot
to the PIC1 6F506, whi ch is de scrib ed in the same dat a
sheet (DS41268D):
1. Module: Analog-to-Digital Converter
(ADC)
The specifications listed in Table 1 supersede
Table 13-3 in DS41268D. The PIC12F510 will
meet the performance specifications stated in
Table 1 below if the device is operated as
described in this Errata.
TABLE 1: A/D CONVERTER CHARACTERISTICS
Work around

2. Module: Analog-to-Digital Converter
(ADC)
Section 9.1 “Clock Divisors”, paragraph 1
should read as shown in bold.
The ADC has 4 clock source settings,
ADCS<1:0>. There a re 3 divisor v alu es , 16, 8 an d
4. The fou r th se ttin g is INTOSC with a divis or of 4.
Table 9-2 below should replace the current
Table 9-2 in the data sheet.

Note: Corrections are shown in bold. Where
possible, the original bold text formatting

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 i t s family of products is one of the most secure families of it s 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 c onstantly evolving. We a t Microc hip are co m mitted to continuously improving the code prot ect ion featur es of our
products. Attempts to break Microchip’ s code protection feature may be a violation of the Digital Millennium Copyright Act. If such act s
