Operating Temperature

The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.

0°C ~ 70°C

Max Operating Temperature

The Maximum Operating Temperature is the maximum body temperature at which the thermistor is designed to operate for extended periods of time with acceptable stability of its electrical characteristics.

70 °C

Min Operating Temperature

0 °C

Voltage - Supply

2.7V ~ 3.7V

Operating Supply Voltage

The voltage level by which an electrical system is designated and to which certain operating characteristics of the system are related.

3 V

Interface

Parallel

Max Supply Voltage

In general, the absolute maximum common-mode voltage is VEE-0.3V and VCC+0.3V, but for products without a protection element at the VCC side, voltages up to the absolute maximum rated supply voltage (i.e. VEE+36V) can be supplied, regardless of supply voltage.

3.7 V

Min Supply Voltage

The minimum supply voltage (V min ) is explored for sequential logic circuits by statistically simulating the impact of within-die process variations and gate-dielectric soft breakdown on data retention and hold time.

2.7 V

Memory Size

The memory capacity is the amount of data a device can store at any given time in its memory.

8KB

Clock

Time Format

Time is based on a 24 hour system. This is frequently referred to as "military time". The 24 hour system is the default format.

HH:MM:SS (12/24 hr)

Date Format

The international standard recommends writing the date as year, then month, then the day:?YYYY-MM-DD.

Radiation Hardening

Radiation hardening is the process of making electronic components and circuits resistant to damage or malfunction caused by high levels of ionizing radiation, especially for environments in outer space (especially beyond the low Earth orbit), around nuclear reactors and particle accelerators, or during nuclear accidents or nuclear warfare.
