I²C bus SERIAL INTERFACE REAL-TIME CLOCK IC

WITH VOLTAGE MONITORING FUNCTION

NO.EA-079-0208

RV5C386A

OUTLINE

The RV5C386A is a CMOS real-time clock IC connected to the CPU by two signal lines, SCL and SDA, and

configured to perform serial transmission of time and calendar data to the CPU. The periodic interrupt circuit is

configured to generate interrupt signals with six selectable interrupts ranging from 0.5 seconds to 1 month. The 2

alarm circuits generate interrupt signals at preset times. The oscillation circuit is driven under constant voltage so

that fluctuations in oscillation frequency due to voltage are small and supply current is also small (TYP. 0.35µA at 3

volts). The oscillation halt sensing circuit can be used to judge the validity of internal data in such events as power-

on. The supply voltage monitoring circuit is configured to record a drop in supply voltage below two selectable

supply voltage monitoring threshold settings. The 32-kHz clock output function (CMOS push-pull) is intended to

output sub-clock pulses for the external microcomputer. The 32-kHz clock circuit can be disabled by certain input

pin. The oscillation adjustment circuit is intended to adjust time counts with high precision by correcting deviations

in the oscillation frequency of the crystal oscillator. This model comes in an ultra-compact 10-pin SSOP-G (with a

height of 1.20mm and a pin pitch of 0.5mm).

FEATURES

• Timekeeping supply voltage ranging from 1.45 to 5.5 volts

• Low supply current: TYP. 0.35µA (MAX. 0.8µA) at 3 volts

• Only two signal lines (SCL, SDA) required for connection to the CPU.

(I²C bus compatible, 400kHz at VDD≥2.5V, address 7bits)

• Time counters (counting hours, minutes, and seconds) and calendar counters (counting years, months, days,

and weeks) (in BCD format)

• 1900/2000 identification bit for Year 2000 compliance

• Interrupt circuit configured to generate interrupt signals (with interrupts ranging from 0.5 seconds to 1 month)

to the CPU and provided with an interrupt flag and an interrupt halt circuit

• 2 alarm circuits (Alarm_W for week, hour, and minute alarm settings and Alarm_D for hour and minute

alarm settings)

• 32-kHz clock circuit (CMOS output, equipped with a control pin)

• Oscillation halt sensing circuit which can be used to judge the validity of internal data

• Supply voltage monitoring circuit with two supply voltage monitoring threshold settings

• Automatic identification of leap years up to the year 2099

• Selectable 12-hour and 24-hour mode settings

• High precision oscillation adjustment circuit

• Built-in oscillation stabilization capacitors (C^Gand CD)

• CMOS process

• Ultra-compact 10-pin SSOP-G(with a height of 1.20mm and size 4.0mm×2.9mm)
