Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to VSS unless otherwise noted. 2. Under steady state (non-transient) conditions, IOL must be externally limited as follows: Maximum IOL per port pin: 10mA (NOTE: This is 85 °C spec.) Maximum IOL per 8-bit port: 26mA Maximum total IOL for all outputs: 67mA 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. 3. Pins of ports 1 and 3 source a transition current when they are being externally driven from 1 to 0. The transition current reaches its maximum value when VIN is approximately 2V. 4. Power-down ICC is measured with all output pins disconnected; port 0 = VCC; X2, X1 n.c.; RST = VSS. 5. Active ICC is measured with all output pins disconnected; X1 driven with tCLCH, tCHCL = 5ns, VIL = VSS + 0.5V, VIH = VCC – 0.5V; X2 n.c.; RST = port 0 = VCC. ICC will be slightly higher if a crystal oscillator is used. 6. Idle ICC is measured with all output pins disconnected; X1 driven with tCLCH, tCHCL = 5ns, VIL = VSS + 0.5V, VIH = VCC – 0.5V; X2 n.c.; port 0 = VCC; RST = VSS. AC ELECTRICAL CHARACTERISTICS Tamb = 0°C to +70°C or –40°C to +85°C, VCC = 5V ±10%, VSS = 0V1, 2 VARIABLE CLOCK SYMBOL PARAMETER MIN MAX MIN MAX UNIT 1/tCLCL Oscillator frequency: 3.5 16 3.5 40 MHz External Clock (Figure 2) tCHCX High time 20 10 ns tCLCX Low time 20 10 ns tCLCH Rise time 20 20 ns tCHCL Fall time 20 20 ns NOTES: 1. Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to VSS unless otherwise noted. 2. Load capacitance for ports = 80pF. |
