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.
