Silicon Errata and Data Sheet Clarification
The Rev. C0 PIC16F506 devices that you have received
conform functionally to the current Device Data Sheet
(DS41268D), except for the anomalies described in this
document.
The silicon/specification issues discussed in the
following pages are for silicon revision C0. If questions
arise concerning the silicon revision received in a
particular factory shipment, please contact your local

Data Sheet Clarifications
The following typographic corrections and clarifications
are to be noted for the latest version of the device data
sheet (DS41268D):
Note:
Corrections are shown in
bold.
Where
possible, the original bold text formatting
has been removed for clarity.
1. Module: Analog-to-Digital Converter
(ADC)
For the PIC16F506, the specifications listed in
Table 1 below supersede Table 13-3 in the device
data sheet (DS41268D). These changes do not
apply to the PIC12F510, which is also described on
data sheet DS41268D.

Data in the Typical (“Typ”) column is based on characterization results at 25°C. This data is for design
guidance only and is not tested.
The supply current is mainly a function of the operating voltage and frequency. Other factors such as bus
loading, oscillator type, bus rate, internal code execution pattern and temperature also have an impact on
the current consumption.
The test conditions for all I

measurements in active operation mode are:
OSC1 = external square wave, from rail-to-rail; all I/O pins tri-stated, pulled to V
