The PIC18F2450/4450 (Rev. A1) parts you have

received conform functionally to the Device Data Sheet

(DS39760A), except for the anomalies described

below. Any data sheet clarification issues related to this

device will be reported in a separate data sheet errata.

Please check the Microchip web site for any existing

issues.

The

PIC18F2450/4450 devices with these Device/Revision

IDs:

The Device IDs (DEVID1 and DEVID2) are located at

addresses 3FFFFEh:3FFFFFh in the device’s configu-

ration space. They are shown in hexadecimal in the

format “DEVID2 DEVID1”.

Param

In Asynchronous mode, the reception can get

corrupted if any bit of the TXSTA register is

modified during a reception.

Work around

Maintain

(TXSTA<4>) bits as ‘0’. Though the CSRC

(TXSTA<7>) bit is a don’t care in Asynchronous

mode, make sure that this bit is not set.

2. Module: A/D (Offset)

—

The A/D offset is greater than the specified limit in

Table 21-17 of the Device Data Sheet. The

updated conditions and limits are shown in bold

text in Table 1.

Work around

There are three work arounds:

1. Configure the A/D to use the V

2. Perform a conversion on a known voltage

3. Increase system clock speed and adjust A/D
