PIC16C54C/55A/56A/57C/58B
The PIC16C54C/55A/56A/57C/58B (Rev. A Silicon
ONLY) part s you have rec eive d conform functi onally to
the PIC16C5X Dev ice Data Sheet (DS30 453D), exce pt
for the anomalies described below.
All the problems list ed here will be addressed in future
revisions of the PIC 16C54C/55A/56A/57C/58B silicon.
1. Module: RESET
The minimum specification for the MCLR must be met
in order to RESET the PIC16C54C/55A/56A/57C/58B.
If a MCLR pulse occurs that is less than the minimum
specification (parameter #30), improper device opera-
tion can occur.
If the minimum specification cannot be met, then an
external circuit must be used to ensure that any pulse
width, less than the specif ication, will be filtered before
it reache s the MCLR pin.
Work around
A possible circuit is shown in Figure 1. Proper design
validation needs to be done to ensure desired opera-
tion over the applications operating conditions.

Note the following details of the code protection feature on PICm icro® MCUs.
• The PICmicro family meets the specifications contained in the Microchip Data Sheet.
• Microchip believes that its family of PICmicro microcontrollers is one of the most secure products 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 knowl-
edge, require using the PICmicro microcontroller in a manner outside the operating specifications contained in the data sheet.
The person doing so may be 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 a s “unbreakable”.
• Code protection is constant ly evolving. We at Microchip are committed to continuously i mproving the code protection features of
our product.
