Active - 12 MHz

VCC = 3.6 V

Idle - 24 MHz

Active - 40 MHz

VCC = 3.6 V

Idle - 40 MHz

Power supply (VCC, AVCC) is always 3.0 to 3.6 V for the MCU module. VDD for the PSD module may be

3 V or 5 V.

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

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

other pins are disconnected.

ICC-CPU (Active mode) is measured with: XTAL1 driven with tCLCH, tCHCL = 5 ns, 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 1mA).

ICC-CPU (Idle Mode) is measured with: XTAL1 driven with tCLCH, tCHCL = 5 ns, 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 and the MCU clock is

set to fOSC/2048.

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