RS5C348A-E2-F Descrizione generale

Epson's RS5C348A-E2-F real-time clock (RTC) module is a highly reliable and accurate timekeeping solution for electronic devices. This module operates within a voltage range of 1.6V to 5.5V, making it suitable for a variety of applications. Its low power consumption of 130μA ensures minimal energy usage, ideal for battery-powered devices. The integrated 32.768 kHz crystal oscillator provides precise timing, while the built-in calendar with automatic leap year correction and leap year transition ensures accurate date tracking. The RS5C348A-E2-F supports both 24-hour and 12-hour formats and includes alarm functions with programmable interrupt output, offering versatile functionality for different application needs. Additionally, its compact size of 3.2mm x 2.5mm x 1.0mm makes it suitable for space-constrained designs. With an operating temperature range from -40°C to +85°C, this module guarantees reliable performance in various environmental conditions

Caratteristiche principali

● Timekeeping supply voltage ranging from 1.45 to 5.5V
● Low power consumption
Rx5C348A: 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
