5 / 28 page  - 5 - SM5K3/SM5K4/SM5K5 RECOMMENDED OPERATING CONDITIONS (SM5K3/5K5) PARAMETER SYMBOL CONDITIONS RATING UNIT Supply voltage VDD 2.2 to 5.5 V Instruction cycle TSYS VDD = 2.2 to 5.5 V 2 to 61 µs VDD = 5.0 V ± 10% 1 to 61 Main clock frequency (OSCIN-OSCOUT) fOSC VDD = 2.2 to 5.5 V 1 M to 32.768 k Hz VDD = 5.0 V ± 10% 2 M to 32.768 k (SM5K4) NOTES : • The typical oscillation frequency shall be determined in consideration of operating condition and fluctuation frequency. • Mount Rf, RD, C1, C2, Oscillator (SM5K3/5K5)/Rf (SM5K4) as close as possible to the oscillator pins of the LSI, in order to reduce an influence from floating capacitance. • Since the value of resistor Rf, RD, C1, C2, Oscillator (SM5K3/5K5)/Rf (SM5K4) varies depending on circuit pattern and others, the final Rf, RD, C1, C2, Oscillator (SM5K3/5K5)/Rf (SM5K4) value shall be determined on the actual unit. • Don't connect any line to OSCIN and OSCOUT except oscillator circuit. • Don't put any signal line across the oscillator circuit line. • On the multilayer circuit, do not let the oscillator circuit wiring cross other circuit. • Minimize the wiring capacitance of GND and VDD . OSCILLATION CIRCUIT PARAMETER SYMBOL CONDITIONS RATING UNIT Supply voltage VDD 2.7 to 5.5 V Instruction cycle TSYS VDD = 2.7 to 5.5 V 2 to 5 µs VDD = 5.0 V ± 10% 1 to 5 Main clock frequency ∗ (OSCIN-OSCOUT) fOSC VDD = 2.7 to 5.5 V 1 M to 400 k Hz VDD = 5.0 V ± 10% 2 M to 400 k ∗ Degree of fluctuation frequency : ± 20% OSCOUT OSCIN Rf Rf = 33 k Ω (fosc = 1.67 MHz, TYP.) • SM5K3/5K5 ∗ Reference only : Circuit configuration varies according to oscillator used. • SM5K4 OSCOUT OSCIN Rf RD Oscillator C1 C2 |
