The PIC16C781/782 parts you have received conform

functionally to the Device Data Sheet (DS41171A),

except for the anomalies described below.

Note:

Module:

Controller (PSMC)

In the Pulse Width Mode (PWM) when a compara-

tor threshold crossing event occurs after the mini-

mum duty cycle time (Min DC) and coincident with

a PSMC clock edge, the pulse output of the PSMC

will immediately and correctly go to the inactive

state. One PSMC clock period later, the output

may incorrectly become active and remain active

until the pulse terminates at the completion of the

maximum duty cycle time (Max DC).

Work around

If possible, use the Pulse Skipping Mode (PSM). If

your application requires PWM, then please

contact your local Microchip representative.

PIC16C781/782 Rev. B1 Silicon/Data Sheet Errata

The silicon revision of a specific compo-

nent is identified by its manufacture date

code: YYWW, YY is the year of manufac-

ture and WW is the specific work week. All

material with a date code of 0228 or earlier

is revision B1 silicon, and subject to the

Errata contained in this document. Any

components with a latter date code will be

silicon revision B3 or latter and will be cov-

ered in a separate Errata. For additional

information concerning date codes, refer to

the packaging information section of the

PIC16C781/782 data sheet (DS41171A).

Mode

PIC16C781/782

Note:

Module:

When the voltage comparator inputs are subjected

to fast rise time pulses, some units exhibit a

momentary invalid state on their output. The prob-

ability of generating an invalid output state is

dependant upon four factors:

1. Pulse slew rate

2. Supply Voltage (V

3. Ambient Temperature

4. Reference Voltage (V

Figures 1 through 5 show the input slew rate limits

for normal operation of the voltage comparators in

Fast mode, for a variety of Common mode volt-

ages, supply voltages and ambient temperatures.

If the PSMC is used in conjunction with the voltage

comparators, an invalid voltage comparator output

state can cause the premature termination of

PSMC output pulses.

Work around

The pulse rise time of inputs to the voltage com-

parators should be less than the limits shown in

Figures 1 through 5 for the specific conditions of

operation (supply voltage, temperature, Common

mode voltage). The values shown are for pulses

with a constant rise time. For pulses with com-

pound rise times (pulses with non-linear or chang-

ing slopes), the limits may be different.

The area below the line for any given tem-

perature is the safe operating area.
