ST52510xx ST52513xx
16.8 Programmable Low Voltage Detector (PLVD)
Operating Conditions: TA= 25 C, unless otherwise specified.
Notes:
1. Measured with V
2. Duration of the glitch not detected by the PLVD. Values by design, not tested in production.
16.9 Internal oscillator
The frequency of the internal oscillator is centered at 10 MHz but can be subject to variation due to process
spread: this may be calibrated by using the related option byte.
Operating Conditions: V
Notes:
1. Drift values in temperature are calculated with respect to internal oscillator frequency value at T
