Flash memory
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.
Switching regulator supply
voltage (supplied via the
power jack or VIN pin)
unregulated, 8-20V input range, 12V nominal

(supplied via the 3.3V pin
bypassing the switching
regulator)
regulated, 3.3V +/- 10%
Available current on the 3.3V
pin (when powering through
the voltage regulator)
1.0A if the WA2000 is used
1.3A if the WA2000 is not used
Reset circuit trip voltage
(3.3V system power line)
3.0V on power-up (i.e. when the voltage is
rising)
2.9V on brown-out (i.e. when the voltage is
dropping)
Operating current when the
3.3V is supplied directly
through the 3.3V pin
