Auxiliary Block Specifications1 Parameter Symbol Test Condition Min Typ Max Unit Temperature Sensor Sensitivity TSS — 4.5 — ADC Codes/ °C Low Battery Detector Resolution LBDRES —50 — mV Microcontroller Clock Output Frequency Range2 FMC Configurable to Fxtal or Fxtal divided by 2, 3, 7.5, 10, 15, or 30 where Fxtal is the reference XTAL frequency. In addition, 32.768 kHz is also supported. 32.768K — Fxtal Hz Temperature Sensor Conversion TEMPCT Programmable setting — 3 — ms XTAL Range3 XTALRange 25 — 32 MHz 30 MHz XTAL Start-Up Time t30M Start-up time will vary with XTAL type and board layout. — 300 — µs 30 MHz XTAL Cap Resolution 30MRES —70 — fF 32 kHz XTAL Start-Up Time t32k —2 — sec 32 kHz Accuracy using Internal RC Oscillator 32KRCRES — 2500 — ppm POR Reset Time tPOR —— 6 ms Notes: 1. All minimum and maximum values are guaranteed across the recommended operating conditions of supply voltage and from –45 to +85 °C unless otherwise stated. All typical values apply at Vdd=3.3V and 25C unless otherwise stated. 2. Microcontroller clock frequency tested in production at 1 MHz, 30 MHz, 32 MHz, and 32.768 kHz. Other frequencies tested by bench characterization. 3. XTAL Range tested in production using an external clock source (similar to using a TCXO). |
