3-WIRE SERIAL INTERFACE REAL-TIME CLOCK IC
WITH VOLTAGE MONITORING FUNCTION
RV5C339A
OUTLINE
The RV5C339A is a CMOS real-time clock IC connected to the CPU by three signal lines CE (Chip Enable), SCLK
(Serial Clock), and SIO (Serial Input/Output), and configured to perform serial transmission of time and calendar
data to the CPU. This model incorporates different functional circuits. 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 (Nch. open drain) is intended to
output sub-clock pulses for the external microcomputer. 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 (at 25˚C)
• Only three signal lines (SCLK, SIO, and CE) required for connection to the CPU.
Maximum clock frequency of 2 MHz (with VDD of 5 volts)
• 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 (Nch. open drain output)
Designed to disable 32-kHz clock output in response to a command from the host computer.
• 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
• Built-in oscillation stabilization capacitors (CG and CD)
• High precision oscillation adjustment circuit
• CMOS process
• Ultra-compact 10-pin SSOP-G (with a height of 1.20mm and size of 4.0
×2.9mm)
