Description
The RV5C338A-E2-F is a CMOS real-time clock IC that is designed to be connected to the CPU using three signal lines: Chip Enable (CE), Serial Clock (SCLK), and Serial Input/Output (SIO). It is capable of performing serial transmission of time and calendar data to the CPU. This model incorporates various functional circuits to provide reliable timekeeping and calendar functions.
Specifications and 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 (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
- Built-in oscillation stabilization capacitors (CG and CD)
- High precision oscillation adjustment circuit
- CMOS process
- Ultra-compact 10-pin SSOP (RS5C338A with a height of 1.25mm and size of 6.4×3.5mm)
- Ultra-compact 10-pin SSOP-G (RV5C338A with a height of 1.20mm and size of 4.0×2.9mm)
Application Scenarios
The RV5C338A-E2-F can be used in a wide range of applications that require accurate timekeeping and calendar functions. It is especially suitable for devices that need to keep track of time and date, such as timers, clocks, data loggers, and electronic calendars.
