Description



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

Description

Pin No. Symbol Name Description
7 CE Chip Enable Input The CE pin is used for interfacing with the CPU. Should be held high to allow
access to the CPU. Incorporates a pull-down resistor. Should be held low or open
when the CPU is powered off. Allows a maximum input voltage of 5.5 volts regard-
less of supply voltage.
2 SCLK Serial Clock Input The SCLK pin is used to input clock pulses synchronizing the input and output of
data to and from the SIO pin. Allows a maximum input voltage of 5.5 volts regard-
less of supply voltage.
3 SIO Serial Input/Output The SIO pin is used to input and output data intended for writing and reading in
synchronization with the SCLK pin. CMOS input/output.
6 IATRA Interrupt Output A The IATRA  pin is used to output periodic interrupt signals to the CPU and alarm
interrupt signals (Alarm_D). Disabled at power-on from 0 volts.
Nch. open drain output.
4 IATRB Interrupt Output B The IATRB pin is used to output alarm interrupt signals (Alarm_W). Disable at
power-on from 0 volts. Nch. open drain output.
1 32KOUT 32-kHz Clock Output The 32KOUT pin is used to output 32.768-kHz clock pulses. Enabled at power-on
from 0 volts. Nch. open drain output. The RV5C339A is designed to be disabled
32-kHz clock output in response to a command from the host computer.
