PIC16F818/819
The PIC16F818/819 Rev. A4 parts you have received
conform functionally to the Device Data Sheet
(DS39598E), except for the anomalies described
below.
Microchip intends to address all issues listed here in
future revisions of the PIC16F818/819 silicon.
The following silicon errata apply only to
PIC16F818/819 devices with these Device/Revision
IDs:
1. Module: Internal RC Oscillator
The INTOSC and INTOSC with postscaler outputs
may exhibit a high amount of jitter.
Work around
None
Date Codes that pertain to this issue:
All date codes up to 0426xxx.
2. Module: PORTB
If the following conditions are present on RB3, a
device Reset may occur.
1. RC combination on RB3 (see Figure 1).
2. RB3 configured as an input via TRISB.
3. RB3 is driven low.
FIGURE 1:
Work around
1. A Reset condition may not occur if a specific
resistor/capacitor combination is used. It has
been observed that a 10 kΩ resistor and a
capacitor value of 4.7 nF or less does not cause
a device Reset. If the user must have a RC
configuration using RB3, then experimenting
with different RC values is recommended.
2. Do not configure RB3 with the above con-
ditions shown in Figure 1. Instead, use another
I/O pin for the RC configuration.
Date Codes that pertain to this issue:
All date codes up to 0426xxx.
