PIC16F7X7

The PIC16F7X7 Rev. A2 parts you have received

conform functionally to the Device Data Sheet

(DS30498C), except for the anomalies described

below.

All of the issues listed here will be addressed in future

revisions of the PIC16F7X7 silicon.

The following silicon errata apply only to

PIC16F7X7 devices with these Device/Revision IDs:

1. Module: Internal RC Oscillator

A high Sleep current will exist when the following

condition is met and procedures are followed:

CONDITION: FOSC<2:0> (Configuration Word

selection other than the internal RC oscillator.

PROCEDURE:

1. Clock switch occurs anywhere in the applica-

tion code where the internal RC oscillator is

selected via the SCS bits (‘10’).

2. Sleep mode is entered while the SCS bits are

configured for the internal RC oscillator (‘10’).

Work around

Before Sleep mode is entered, configure or clear

the SCS bits (‘00’) to switch back to the primary

clock source that is defined by FOSC<2:0>

(Configuration Word Register 1).

PIC16F7X7 PIC16F7X7 Rev. A2 Silicon/Data Sheet Errata The PIC16F7X7 Rev. A2 parts you have received conform functionally to the Device Data Sheet (DS30498C), except for the anomalies described below. All of the issues listed here will be addressed in future revisions of the PIC16F7X7 silicon.

PIC16F7X7 2. Module: Internal RC Oscillator IOFS bit The device data sheet states when an INTOSC frequency is selected (125, 250, 500 kHz, 1, 2, 4, 8 MHz), the frequency will be stable when the IOFS bit becomes set (IOFS = 1) at 4 ms. The following applies for applications relying on time dependent code. Under the following conditions, any of the INTOSC frequencies may not be stable when IOFS becomes set (IOFS = 1). Devices may vary from one to the next and may take as long as 60 ms to become stable. 1.

PIC16F7X7 3. Module: Internal RC Oscillator When any one of the seven INTOSC frequencies is enabled by the following conditions, it is possible for the oscillator to overshoot the selected frequency: 1. A clock switch from INTRC (31 kHz) to an INTOSC (125 kHz-8 MHz) frequency via the IRCF bits (OSCCON register). 2. Exit from Sleep mode with the IRCF bits already configured for an INTOSC frequency. 3.

PIC16F7X7 1. Module: DC Characteristics (BOR Specifications) Clarifications/Corrections to the Data Sheet: In the Device Data Sheet (DS30498C), the following clarifications and corrections should be noted. The specifications and parameter numbers for the Brown-out Voltage limits (VBOR, originally parameter D005) in Section 18.1 “DC Characteristics: Supply Voltage” of the Device Data Sheet have been changed. The new information is shown in bold text. 18.

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.
