Supply voltage(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 5 V.

3.0

3.6

VIH

High level input voltage

(Ports 1, 3, 4, MCUAD0-7, MCUA8-11, XTAL1,

RESET)

5 V tolerant - max voltage 5.5 V

3.0 V < VCC < 3.6 V

0.7VCC

5.5(2)

Port 1 is not 5 V tolerant; maximum VIH = VCC + 0.5

VIL

Low level input voltage

(Ports 1, 3, 4, MCUAD0-7, MCUA8-11, XTAL1,

RESET)

3.0 V < VCC < 3.6 V VSS – 0.5

0.3VCC

VOL1

Output low voltage (Port 4)

IOL = 10 mA

0.6

VOL2

Output low voltage (Other Ports)

IOL =5 mA

0.6

VOH1

Output high voltage (Ports 4 push-pull)

IOH = –10 mA

2.4

VOH2

Output high voltage (Port 0 push-pull)

IOH = –5 mA

2.4

VOH3

Output high voltage (Other Ports Bi-directional

mode)

IOH = –20 µA

2.4

VOP

XTAL open bias voltage (XTAL1, XTAL2)

IOL = 3.2 mA

1.0

µA

IFR

XTAL feedback resistor current (XTAL1)

XTAL1 = VCC;

XTAL2 = VSS

–20

µA

IIHL1

Input high leakage current (Port 0)

VSS < VIN < 5.5 V

–10

µA

IIHL2

Input high leakage current (Port 1, 2, 3, 4)

VIH = 2.3 V

–10

µA

IILL

Input low leakage current (Port 1, 2, 3, 4)

VIL < 0.5 V

–10

µA

IPD

(3)

IPD (Power-down mode) is measured with: XTAL1 = VSS; XTAL2 = NC; RESET = VCC; Port 0 = VCC; all other pins are

disconnected.

Power-down mode

VCC = 3.6 V

µA

ICC-CPU

(4)(5)(6)

ICC-CPU (Active mode) is measured with: XTAL1 driven with tCLCH, tCHCL = 5ns, VIL = VSS + 0.5 V, VIH = VCC – 0.5 V,

XTAL2 = NC; RESET = VSS; Port 0 = VCC; all other pins are disconnected. ICC would be slightly higher if a crystal oscillator

is used (approximately 1 mA).

ICC-CPU (Idle mode) is measured with: XTAL1 driven with tCLCH, tCHCL = 5ns, VIL = VSS + 0.5 V, VIH = VCC – 0.5 V, XTAL2

= NC; RESET = VCC; Port 0 = VCC; all other pins are disconnected. ICC would be slightly higher if a crystal oscillator is used

(approximately 1 mA). All IP clocks are disabled.

I/O current = 0 mA, all I/O pins are disconnected.

Active - 12 MHz

VCC = 3.6 V

Idle - 12 MHz

Active - 24 MHz

VCC = 3.6 V

Idle - 24 MHz

Active - 40 MHz

VCC = 3.6 V

Idle - 40 MHz
