266 / 293 page  DC and AC parameters uPSD34xx 266/293 Note: 1 Power supply (VCC, AVCC) is always 3.0 to 3.6V for the MCU Module. VDD for the PSD Module may be 3V or 5V. 2 Port 1 is not 5V tolerant; maximum VIH = VCC + 0.5. 3IPD (Power-down Mode) is measured with: XTAL1 = VSS; XTAL2 = NC; RESET = VCC; Port 0 = VCC; all other pins are disconnected. 4ICC-CPU (Active Mode) is measured with: XTAL1 driven with tCLCH, tCHCL = 5ns, VIL = VSS + 0.5V, VIH = VCC – 0.5V, XTAL2 = NC; RESET = VSS; Port 0 = VCC; all other pins are disconnected. ICC would be slightly higher if a crystal oscillator is used (approximately 1mA). 5ICC-CPU (Idle Mode) is measured with: XTAL1 driven with tCLCH, tCHCL = 5ns, VIL = VSS + 0.5V, VIH = VCC – 0.5V, XTAL2 = NC; RESET = VCC; Port 0 = VCC; all other pins are disconnected. ICC would be slightly higher if a crystal oscillator is used (approximately 1mA). All IP clocks are disabled and the MCU clock is set to fOSC/2048. 6 I/O current = 0mA, all I/O pins are disconnected. VOH1 Output High Voltage (Ports 4 push-pull) IOH = –10mA 2.4 V V VOH2 Output High Voltage (Port 0 push-pull) IOH = –5mA 2.4 V V VOH3 Output High Voltage (Other Ports Bi-directional mode) IOH = –20µA 2.4 V V VOP XTAL Open Bias Voltage (XTAL1, XTAL2) IOL = 3.2mA 1.0 2.0 V IRST RESET Pin Pull-up Current (RESET) VIN = VSS –10 –55 uA IFR XTAL Feedback Resistor Current (XTAL1) XTAL1 = VCC; XTAL2 = VSS –20 50 uA IIHL1 Input High Leakage Current (Port 0) VSS < VIN < 5.5V –10 10 uA IIHL2 Input High Leakage Current (Port 1, 3, 4) VIH = 2.3V –10 10 uA IILL Input Low Leakage Current (Port 1, 3, 4) VIL < 0.5V –10 10 uA IPD (3) Power-down Mode VCC = 3.6V 65 95 uA ICC-CPU (Notes 4,5,6) Active - 12MHz VCC = 3.6V 14 20 mA Idle - 12MHz 10 12 mA Active - 24MHz VCC = 3.6V 19 30 mA Idle - 24MHz 13 17 mA Active - 40MHz VCC = 3.6V 26 40 mA Idle - 40MHz 17 22 mA Symbol Parameter Test Conditions Min.
