external buzzer
Real-time counter (RTC)
40 bit, increments at 128Hz, has its own backup
power input
RTC backup power source
Supercapacitor, supports RTC for app. 6 days ("-S"
version only); alternatively, external supercapacitor
or backup battery can be connected.

Flash memory
512KBytes or 1024KBytes, the entire memory minus
64KB is available for storing Tibbo BASIC/C
application and data.
Typical write endurance is 100'000 write cycles per
256-byte sector. See the warning in Flash and
EEPROM Memory.
EEPROM memory
2048 bytes, 2020 bytes available for storing
application data.
Typical write endurance is around 1'000'000 write
cycles per 16-byte EEPROM sector. See Prolonging
and Estimating EEPROM life.
