PIC18F2480/2580/4480/4580 Data Sheet Errata
Clarifications/Corrections to the Data
Sheet
In the PIC18F2480/2580/4480/4580 Device Data
Sheet (DS39637C), the following clarifications and cor-
rections should be noted. Any silicon issues related to
this device will reported in a separate silicon errata.
Please check the Microchip web site for any existing
issues.
2. Module: Master Synchronous Serial Port
(MSSP) – Serial Peripheral
Interface (SPI)
The following note has been added to the end of
Section 17.3.3 “Enabling SPI I/O”.
Note:
1. Module: Enhanced Capture/Compare
PWM (ECCP1)
The following note has been added to the end of
Section 16.4.6 “Programmable Dead-Band
Delay”.
When the module is enabled and in
Master mode (CKE, SSPSTAT<6> =
1),
a
small glitch of approximately half a T
CY
may be seen on the SCK pin. To resolve
this, keep the SCK pin as an input while
setting SPEN. Then, configure the SCK
pin as an output (TRISC<3> =
0).
Note:
If the dead-band delay value is increased
after the dead-band time has elapsed, that
new value takes effect immediately. This
happens even if the PWM pulse is high
and can appear to be a glitch.
Dead-band values must be changed
during the dead-band time or before
ECCP is active.

Shading of rows is to assist in readability of the table.
This is the limit to which V
DD
can be lowered in Sleep mode, or during a device Reset, without losing RAM data.
With BOR enabled, full-speed operation (F
OSC
= 40 MHz) is supported until a BOR occurs. This is valid, although V
DD
may be below the minimum voltage for this frequency.

Note the following details of the code protection feature on Microchip devices:
•
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
Microchip is willing to work with the customer who is concerned about the integrity of their code.
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
