TS8xCx2X2
4184I–8051–02/08
Port 0: 26 mA
Ports 1, 2 and 3: 15 mA
Maximum total IOL for all output pins: 71 mA
If IOL exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater
than the listed test conditions.
7. For other values, please contact your sales office.
8. Operating ICC is measured with all output pins disconnected; XTAL1 driven with TCLCH, TCHCL = 5 ns (see Figure 17.), VIL =
VSS + 0.5V,
VIH = VCC - 0.5V; XTAL2 N.C.; EA = Port 0 = VCC; RST = VSS. The internal ROM runs the code 80 FE (label: SJMP label). ICC
would be slightly higher if a crystal oscillator is used. Measurements are made with OTP products when possible, which is
the worst case.
