The PIC18FXX8 Rev. C0 parts you have received

conform functionally to the Device Data Sheet

(DS41159D), except for the anomalies described

below.

The

PIC18FXX8 devices with these Device/Revision

IDs:

1. Module: Core (Program Memory Space)

The Device IDs (DEVID1 and DEVID2) are located at

addresses

configuration space. They are shown in hexadecimal

in the format “DEVID2 DEVID1”.

Performing table read operations above the user

program memory space (addresses over 1FFFFFh)

may yield erroneous results at the extreme low end

of the device’s rated temperature range (-40°C).

This applies specifically to addresses above

1FFFFFh,

(200000h-200007h),

(300000h-30000Dh) and the device ID locations

(3FFFFEh and 3FFFFFh). User program memory

is unaffected.

Work around

Two possible work arounds are presented. Other

solutions may exist.

1. Do not perform table read operations on areas

2. Insert NOP instructions (specifically, literal

suggested optimal number is 4 instructions

This may vary depending upon the particular

application and should be optimized by the user.

2. Module: Data EEPROM

3. Module: A/D (External Voltage Reference)

When reading the data EEPROM, the contents of

the EEDATA register may be corrupted if the RD

bit (EECON1<0>) is set immediately following a

write to the address byte (EEADR). The actual

contents of the data EEPROM remain unaffected.

Work around

Do not set EEADR immediately before the

execution of a read. Write to EEADR at least one

instruction cycle before setting the RD bit. The

instruction between the write to EEADR and the

read can be any valid instruction, including a NOP.
