66 / 98 page Preliminary Product Information U15436EJ1V0PM 66 µµµµPD703201, 703201Y, 703204, 703204Y, 70F3201, 70F3201Y, 70F3204, 70F3204Y Recommended Oscillator (1) Main clock oscillator (TA = –40 to +85°C) (a) Connection of ceramic resonator or crystal resonator X1 X2 Parameter Symbol Conditions MIN. TYP. MAX. Unit VDD = 2.3 to 2.7 V 2 17 MHz Oscillation frequency fX (fXX) VDD = 2.2 to 2.7 V 2 13.5 MHz Upon reset release 2 19/fX s Oscillation stabilization time Upon STOP mode release Note s Note The TYP. value differs depending on the setting of the oscillation stabilization time select register (OSTS). Caution Ensure that the duty of the oscillation waveform is between 45% and 55%. Remarks 1. Connect the oscillator as close as possible to the X1 and X2 pins. 2. Do not route the wiring near broken lines. 3. For the resonator selection and oscillator constant, customers are requested to either evaluate the oscillation themselves or apply to the resonator manufacturer for evaluation. (b) External clock input X1 X2 High-speed CMOS inverter External clock Open Cautions 1. Connect the high-speed CMOS inverter as close as possible to the X1 pin. 2. Sufficiently evaluate the matching between the V850ES/SA2, V850ES/SA3 and the high- speed CMOS inverter. |
