Known limitations
6.1
Low Power Wait For Interrupt mode
When the STR73x device is put in Low Power Wait For Interrupt mode (LPWFI), the Flash
goes into Low Power mode or Power Down mode, depending on the setting of the PWD bit
in the Flash Control Register 0 (default is ‘0’, Low Power mode). This default mode can
create excessive voltage conditions on the transistor gates and may affect the long term
behavior of the Low Power mode circuitry.
Workaround
There is no workaround. If Low Power Wait For Interrupt mode is used, it is strongly
suggested to configure the Flash to enter Power Down mode (bit PWD = ‘1’).
6.2
PLL free running mode at high temperature
When the STR73x device is operated and an ambient temperature (T
A
) of more than 55°C
and the main system clock (f
MCLK
) is sourced by the PLL in free running mode, the device
may not work properly.
Workaround
At high temperature (more than 55°C), it is recommended to use the internal RC oscillator
as a backup clock source rather than the PLL free running mode.
