Real Time RS 10+
The Real Time RS 10+ is a precision real-time clock module with integrated battery backup and high-accuracy timekeeping capabilities, designed for embedded systems and industrial automation applications. Electronics engineers, IoT developers, and automation technicians rely on this module to maintain accurate time synchronization in microcontroller-based projects, data logging systems, and networked devices without continuous power supply. This product solves the critical problem of time drift in offline operations by providing a dedicated real-time clock with non-volatile memory to preserve time information during power loss.
Product Overview
The Real Time RS 10+ operates on the principle of a battery-backed real-time clock (RTC) integrated circuit that maintains accurate date and time information independent of the main system power supply. The module features a crystal oscillator running at 32.768 kHz, which provides exceptional frequency stability and timing accuracy. The integrated lithium coin cell battery ensures continuous operation for extended periods during power outages, preserving critical timestamp data for industrial logging, financial transactions, and time-critical applications. Communication with host microcontrollers is established through I2C or SPI protocols, allowing seamless integration into existing embedded systems architectures.
What distinguishes the RS 10+ model is its enhanced temperature compensation algorithm and extended battery life specification, delivering accuracy within ±5 seconds per month across the operating temperature range of -40°C to +85°C. The module incorporates multiple alarm functions, programmable square wave output, and dedicated RAM for storing user configuration data. The compact design with standard pinout compatibility ensures drop-in replacement capability in legacy systems while maintaining full backward compatibility with previous Real Time clock modules.

How to Use
Begin by connecting the Real Time RS 10+ module to your microcontroller using the I2C or SPI protocol based on your system architecture. For I2C connection, link the SCL pin to the microcontroller's clock line and SDA pin to the data line, ensuring 4.7 kΩ pull-up resistors are installed on both signal lines. Connect the VCC pin to your 3.3V or 5V power supply and GND to the common ground. The CR2032 backup battery should be inserted into the coin cell holder on the module; the battery will automatically maintain timekeeping during main power loss.
After hardware connection, initialize the RTC through your microcontroller firmware by setting the current date and time using the I2C or SPI communication protocol. Configure the alarm registers if you require interrupt-driven time-based events, and program the square wave output frequency if external timing synchronization is needed. The module's non-volatile RAM can store calibration offsets to compensate for oscillator drift specific to your operating environment. Verify accurate operation by reading the time register periodically and comparing against a known time source; most applications achieve ±2 seconds accuracy after initial calibration.
Frequently Asked Questions
What is the difference between the RS 10+ and standard RTC modules?
The RS 10+ incorporates enhanced temperature compensation circuitry that maintains ±5 seconds per month accuracy across the full -40°C to +85°C industrial temperature range, compared to standard modules that typically achieve ±10-15 seconds per month. The extended battery life specification of 10 years provides superior long-term reliability in applications with infrequent power cycles. Additionally, the RS 10+ includes programmable alarm functions and square wave output capabilities that enable advanced timing applications without additional external components.
Can the RS 10+ be used in 3.3V systems, or does it require 5V?
The Real Time RS 10+ operates across the full 3.3V to 5.5V supply voltage range, making it compatible with both 3.3V and 5V microcontroller systems. When operating at 3.3V, ensure the backup battery voltage (3V CR2032) is sufficient to maintain timekeeping. The I2C and SPI signal levels will automatically adapt to your system voltage through proper pull-up resistor selection. For mixed-voltage systems, use appropriate level-shifting buffers on the communication lines to prevent signal integrity issues.
How long will the CR2032 battery maintain time if the main power is disconnected?
Under standard conditions at 25°C ambient temperature with no load on the module, the CR2032 lithium coin cell provides approximately 10 years of continuous timekeeping operation. However, this duration decreases in higher temperature environments; at 85°C, battery life reduces to approximately 3-5 years due to increased self-discharge rates. The backup current consumption is typically 100-200 microamperes when the main power is absent. We recommend replacing the battery every 5-7 years in critical applications to ensure uninterrupted operation, even though the specified 10-year life provides substantial safety margin.
What communication protocol should I use for my application?
Choose I2C if your microcontroller already has I2C peripherals and you require a simple two-wire connection with multiple devices on the same bus. I2C operates at 400 kHz standard speed and is ideal for systems with moderate timing requirements and space constraints. Select SPI if you need faster communication speeds (up to 1 MHz), lower latency for real-time applications, or if your system already implements SPI for other peripherals. SPI requires four wires (MOSI, MISO, CLK, CS) but provides superior noise immunity in electrically noisy industrial environments.
How do I set the time on the RS 10+ module?
Connect the module to your microcontroller and send the current date and time values through the I2C or SPI interface to the RTC's time registers. Most microcontroller development platforms provide RTC libraries that handle this initialization automatically. You can synchronize time from an external source such as GPS, NTP server, or manual entry. Once set, the module maintains accurate time independently; you only need to update it if the backup battery is depleted or if you require time adjustment for daylight saving time or other scheduling changes.
When will I receive my order?

What is your return and warranty policy?
