Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. Functional operation only guaranteed below 0°C for digital core (VDDC) and system voltages above 1.0 V.
2. Parameters may exceed listed tolerances when out of the temperature range 0 to 50°C.
3. Extended range 55 to 125°C for storage temperature is under qualification.
Electrical Performance Specifications
The tests were performed at 20
°C with a clean 1.8 V supply voltage. BelaSigna 300 was running in low voltage mode (VDDC = 1.2 V).
The system clock (SYS_CLK) was set to 5.12 MHz and the sampling frequency is 16 kHz unless otherwise noted.
Parameters marked as screened are tested on each chip. Other parameters are qualified but not tested on every part.
