118 / 145 page  ST7263BDx ST7263BHx ST7263BKx ST7263BE 118/145 Figure 59. Typ. RPU vs. VDD 14.8.2 Output driving current Subject to general operating condition for VDD, fCPU, and TA unless otherwise specified. Notes: 1. The IIO current sunk must always respect the absolute maximum rating specified in Section 14.2 and the sum of IIO (I/ O ports and control pins) must not exceed IVSS. 2. The IIO current sourced must always respect the absolute maximum rating specified in Section 14.2 and the sum of IIO (I/O ports and control pins) must not exceed IVDD. True open drain I/O pins does not have VOH. 3. The minimum VOH value (with IIO=-10mA) depends on the chosen device type. For Flash devices, min = VDD - 1.3 V and for ROM devices, min = VDD - 1.7 V Rpu (KOhm) 0 20 40 60 80 100 120 140 4 4.2 4.4 4.6 4.8 5 5.2 5.4 Vdd (V) Symbol Parameter Conditions Min Max Unit VOL 1) Output low level voltage for a standard I/O pin when up to 8 pins are sunk at the same time, Port A0, Port A(3:7), Port C(0:2), Port D(0:7) IIO=+1.6mA 0.4 V Output low level voltage for a high sink I/O pin when up to 4 pins are sunk at the same time, Port B(0:7) IIO=+10mA 1.3 Output low level voltage for a very high sink I/O pin when up to 2 pins are sunk at the same time, Port A1, Port A2 IIO=+25mA 1.5 VOH 2) Output high level voltage for an I/O pin when up to 8 pins are sourced at same time IIO=-10mA VDD-1.3 3) IIO=-1.6mA VDD-0.8 |
