Feature
Description
Hardware watchdog
See the
Traveo
TM
Platform Hardware Manual
in detail.
Hardware watchdog function stops during PSS mode. In the related register of HWDG_CFG, the
bit
ALLOWSTOPCLK is always read as 1 (HWDG_CFG.ALLOWSTOPCLK = 1).
The product series doesn’t support Watchdog Counter Monitor Output port. (Related register and
internal circuit is implemented.)
Standby mode
See the
Traveo
TM
Platform Hardware Manual
in detail.
Standby mode with 5 V (or 3 V) single external power supply is available.
Turning off the 1.2 V external power supply in standby mode is available.
The long term pulse of the indicator PWM can be outputted during RTC Standby mode.

Internal Memories
System SRAM
384 KByte
1 wait cycle is necessary for RAM read at over 120MHz.
Internal Memories
TCRAM
128 KByte
Internal Memories
Backup RAM
32 KByte
Backup RAM can only be operated in RUN mode (normal operation mode). In other mode the
memory content should be retained, but it cannot be operated. SLEEP control for Backup RAM
is not supported and cannot be used.
