DC Characteristics
(VCC = 5.0 V
± 10%, VSS = AVSS = 0.0 V, TA = –40 °C to +85 °C)
*1 : P00 to P07, P10 to P17, P20 to P27, P30 to P37
*2 : X0, HST, RST, P40 to P47, P50 to P55, P60 to P67, P70 to P77, P80 to P87, P90 to P97, PA0 to PA4
*3 : MD0, MD1 and MD2
*4 : The current value is preliminary value and may be subject to change for enhanced characteristics without
previous notice. The power supply current is measured with an external clock.
