299 / 320 page  299/320 ST92F120 - ELECTRICAL CHARACTERISTICS RCCU CHARACTERISTICS (VDD =5V ± 10%, TA = –40°C to +105°C, CLoad = 50pF, fINTCLK = 24MHz, unless otherwise specified) Note: (1) Unless otherwise stated, typical data are based on TA=25°C and VDD= 5V. They are only reported for design guide lines not tested in production. RCCU TIMING TABLE (VDD =5V ± 10%, TA = –40°C to +105°C, CLoad = 50pF, fINTCLK = 24MHz, unless otherwise specified) Note: (1) Unless otherwise stated, typical data are based on TA=25°C and VDD= 5V. They are only reported for design guide lines not tested in production. (2) Depending on the delay between rising edge of RESET pin and the first rising edge of CLOCK1, the value can differ from the typical value for +/- 1 CLOCK1 cycle. Legend:Tosc = OSCIN clock periods. PLL CHARACTERISTICS (VDD =5V ± 10%, TA = –40°C to +105°C, CLoad = 50pF, fINTCLK = 24MHz, unless otherwise specified) Note: (1) Unless otherwise stated, typical data are based on TA=25°C and VDD= 5V. They are only reported for design guide lines not tested in production. (2) Measured at 24MHz (INTCLK). Guaranteed by Design Characterisation (not tested). Legend: Tosc = OSCIN clock periods.
