114 / 138 page  ST7L15, ST7L19 114/138 I/O PORT PIN CHARACTERISTICS (cont’d) 13.8.2 Output Driving Current Subject to general operating conditions for VDD, fCPU and TA (-40 to +125°C), unless otherwise specified. Notes: 1. The IIO current sunk must always respect the absolute maximum rating specified in section 13.2.2 on page 99 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 13.2.2 on page 99 and the sum of IIO (I/O ports and control pins) must not exceed IVDD. 3. Not tested in production, based on characterization results. Symbol Parameter Conditions Min Typ Max Unit VOL 1) Output low level voltage for a standard I/O pin when eight pins are sunk at same time (see Figure 77) VDD =5V IIO =+5mA 1.0 V IIO =+2mA 0.4 Output low level voltage for a high sink I/O pin when four pins are sunk at same time (see Figure 80) IIO = +20mA 1.3 IIO =+8mA 0.75 VOH 2) Output high level voltage for an I/O pin when four pins are sourced at same time (see Figure 86) IIO =-5mA VDD -1.5 IIO =-2mA VDD -0.8 VOL 1)3) Output low level voltage for a standard I/O pin when eight pins are sunk at same time (see Figure 76) VDD =3.3V IIO =+2mA, TA ≤ +85°C 0.5 Output low level voltage for a high sink I/O pin when four pins are sunk at same time IIO = +8mA, TA ≤ +85°C VOH 2)3) Output high level voltage for an I/O pin when four pins are sourced at same time (Figure 85) IIO =-2mA, TA ≤ +85°C VDD -0.8 |
