• Manufacturer: STMICROELECTRONICS [STMicroelectronics]

OPERATING CONDITIONS (Cont’d)
13.3.4.2 Devices with ‘”6” order code suffix (tested for T
Notes:
1. If the RC oscillator clock is selected, to improve clock stability and frequency accuracy, it is recommended to place a
decoupling capacitor, typically 100nF, between the V
2. See “INTERNAL RC OSCILLATOR ADJUSTMENT” on page 25.
3. Data based on characterization results, not tested in production
4. Averaged over a 4ms period. After the LOCKED bit is set, a period of t
5. After the LOCKED bit is set ACC
6. Guaranteed by design.
