Manufacturer:YAMAHA
Description:Timekeeping supply voltage ranging from 1.45 to 5.5V Low power consumptionRx5C348A: 0.35µA TYP (0.8µA MAX) at VDD=3V   Rx5C348B: 0.55µA TYP (1.0µA MAX) at VDD=3V Only four signal lines (CE, SCLK, SI, and SO) required for connection to the CPU. Maximum clock frequency of 2 MHz (with VDD = 5V) Time counters (counting hours, minutes, and seconds) and calendar counters (counting years, months, days, and weeks) (in BCD format) 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 2 alarm interrupt circuits (Alarm_W for week, hour, and minute alarm settings and Alarm_D for hour and minute alarm settings) 32-kHz clock output circuit (Nch. open drain output) The Rx5C348A is designed to disable 32-kHz clock output in response to a command from the host computer and the Rx5C348B is designed to keep 32-kHz output enabled. 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 Ultra-compact SSOP10 (RS5C348A/B), SSOP10G (RV5C348A/B), TSSOP10G (RT5C348B) CMOS process
