Silicon Errata Issues

1. Module: High-Frequency Internal

Oscillator (HFINTOSC)

1.1 Internal Oscillator min. VDD

The High-Frequency Internal Oscillator requires a

minimum voltage of 2.3V to operate.

Work around

None.

Affected Silicon Revisions

1.2 HFINTOSC Max. VDD at -40°C

For the LF devices only, the High-Frequency

Internal Oscillator may stop working at -40°C when

VDD is 3.6V.

Work around

None.

Affected Silicon Revisions

2. Module: FVR

2.1 FVR Ready Bit (FVRRDY)

After the FVR is stabilized, the FVR Ready bit may

not be set when the temperature is -40°C and VDD

= 1.8V.

Work around

Operate above -30°C or with VDD >2.0V.

Affected Silicon Revisions

3. Module: Oscillator

3.1 OSCSTAT bits: HFIOFR and HFIOFS

When HFINTOSC is selected, the HFIOFR and

HFIOFS bits will become set when the oscillator

becomes ready and stable. Once these bits are

set,

they

become

“stuck”,

indicating

that

HFINTOSC is always ready and stable. If the

HFINTOSC is disabled, the bits fail to be cleared.

Work around

None.

3.2 Clock Switching

When switching clock sources between INTOSC

clock source and an external clock source, one

corrupted instruction may be executed after the

switch occurs.

This issue affects Two-Speed Start-up and Fail-

Safe Clock Monitor operation.

Work around

When switching from an external oscillator clock

source, first switch to 16 MHz HFINTOSC. Once

running at 16 MHz HFINTOSC, configure IRCF to

run at desired internal oscillator frequency.

When switching from an internal oscillator

(INTOSC) to an external oscillator clock source,

first switch to HFINTOSC High-Power mode (8

MHz or 16 MHz). Once running from HFINTOSC,

switch to the external oscillator clock source.

Affected Silicon Revisions

Note:

This document summarizes all silicon

errata issues from all revisions of silicon,

previous as well as current. Only the

issues indicated by the shaded column in

the following tables apply to the current

silicon revision (A6).
