Silicon Errata Issues
1. Module: ADC (Analog-to-Digital
1.1 ADC Power-down in Sleep
1.2 Error on Infrequent Conversions
 2011 Microchip Technology Inc.
Note:
The ADC module incorrectly fails to power-down
after a conversion if the device is in Sleep and the
ADC interrupt is disabled. The proper operation is
to power the ADC off after the conversion is
complete if the device is sleeping and the ADC
interrupt is disabled.
Work around
Use the ADC conversion complete interrupt
(ADIF) to wake-up and explicitly shut down the
ADC by clearing the ADON bit.
Affected Silicon Revisions
The offset error incorrectly exceeds the data sheet
specifications if time between conversions is
longer than 10 ms. If the time between
conversions is greater than 10 ms, the offset error
is 1 LSb typical and 3.3 LSb maximum.
Work around
The time dependent error is insignificant when the
time between conversions is less than 10 ms.
When the time between conversions is greater
than
conversions and discard the results of the first
conversion.

1.3 Incorrect Conversion below 0°C
2. Module: Timer1
2.1 Operation above 90°C
3. Module: Internal Oscillator
3.1 Frequency Shift on Reset
In some devices, the ADC may improperly convert
if the temperature is below 0°C and the ADC clock
source is set to F
64.
Work around
Set the ADC clock source to F
RC.
Affected Silicon Revisions
The Timer1 oscillator does not operate above
90C.
Work around
None.
Affected Silicon Revisions
The internal oscillator module on the PIC16F72X
family of devices may experience a ±1% frequency
shift after a Reset. The frequency shift is not
consistent and could cause the oscillator to
operate outside of the 2% specification.
Work around
To minimize the chances of experiencing the
frequency shift, the following steps should be
taken:
1. Operate the internal oscillator at 8 MHz or
2. Use an external pull-up on MCLR or use
3. Disable the Power Reset Timer (PWRT).
4. The bypass capacitor and Voltage Regulator
