PIC16F83 Rev. A Silicon Errata Sheet
The PIC16F83 (Rev. A) parts you have received conform
functionally to the Device Data Sheet (DS30430
C
),
except for the anomalies described below.
All the problems listed here will be addressed in future
revisions of the PIC16F83 silicon.
1.
Module: CPU (STATUS bit)
The operation of the power-down (PD) bit in the STA-
TUS register may not function correctly for tempera-
tures below - 20 ˚C.
Work Around
None
2.
Module: Data EEPROM
Do not perform a modify (set or clear a bit) of the
EECON1 register one instruction cycle after an
EEPROM read. This will corrupt the EEDATA regis-
ter.
Example:
BSF
BCF
EECON1, RD
EECON1, WREN
3.
Module: Timer0
The TMR0 register may increment when the WDT
postscaler is switched to the Timer0 prescaler. If
TMR0 = FFh, this will cause TMR0 to overflow (set-
ting T0IF).
Work Around
Follow the following sequence:
a)
b)
c)
d)
Read the 8-bit TMR0 register into the W register
Clear the TMR0 register
Assign WDT postscaler to Timer0
Write W register to TMR0
Work Around
Use either of the following two code segment in place
of the above example.
BSF
NOP
BCF
EECON1, RD
EECON1, WREN
or
BCF
BSF
EECON1, WREN
EECON1, RD
Note:
As with any windowed EPROM device, please cover the window at all times, except when erasing.

Instruction cycle!!! Please help!
What is the clock pulse period of the following instructions? Is it 4us or 6us!!!?? As I understand it, scl2 is 1us, and two empty instructions are 2us, so one cycle should be 6us. But the operating f...
