Function

ROSC

Oscillation control resistance

installation terminal

—

• 1.1 MΩ is installed between GND usually.

• Delay adjustment range of resistance: 650(kΩ) to 1.35(MΩ)

SLP

Sleep mode control

• L: Sleep mode (Power-supply current becomes several μA)

• H: Usually mode

• Terminal is open, Pull-down in GND

Manual reset input

• Low is input, 5pin(VOUT) output the low level

Set the low pulse width by value is longer 3

μs

• Terminal open, pull-up in VDD

GND

—

• Sorcing 0 V.

VOUT

Reset output

• Power-supply voltage reaches the value below the detection

voltage, low is output

• Low level is input to MR terminal, low is output

• Open drain output

• Range pull-up resistance: 10(kΩ) to 100(kΩ)

VREFO

Standard voltage output

• Standard voltage (3.05 V typ) for AD/DA is output

• Outside puts capacity (0.1 μF) by pursuant for microcomputer

VDD

Power-supply terminal

—

• Sorcing power-supply voltage.

Delay time switch

• Delay time is switched. Low: 50 (ms), High: 100 (ms)

• Terminal is open, pull-up in Vdd
