MCP795B21T-I/ST is an ultra-low power real time clock (RTC) and memory device manufactured by Microchip Technology. It is designed to provide timing/clock functions in portable and battery operated applications, such as in medical, wearables, industrial and automotive applications. With its robust features and wide range of support, MCP795B21T-I/ST is the perfect choice for applications requiring extended battery life, reliable time keeping and low power operation.

MCP795B21T-I/ST Clock/Timing - Real Time Clocks come with an embedded oscillator that helps keep time accurate, even when the main power is interrupted. This oscillator produces regular clock pulses, which are then converted into digital signals by the onboard digital circuitry. The digital signals are distributed to different components of the device to keep track of the time, to calculate intervals and to provide alarms. For instance, the device can be used to sound an alarm when a certain amount of time has passed, or when it detects a certain event occurring.

MCP795B21T-I/ST can be configured to provide various features, such as low power backup of real-time, calendar and alarm functions. It is designed to operate at temperatures between -40° Celsius to +85° Celsius (-40°F to +185°F). Operating at very low voltages, this device can realize the full benefit of battery backup and provide uninterrupted timekeeping for extended periods of time.

The device is also capable of providing calendar information, allowing easy transfer of dates and times from one system to another. It also supports leap year setting and leap second adjustment for added accuracy on time measurements. The Programmable Alarm is another useful feature of the device as it allows users to set alarms for different time periods, including a one time alarm only, a daily alarm and a weekly alarm.

In addition, MCP795B21T-I/ST offers 256 bytes of TinyEEPROMTM memory which can be used to store user-programmed data such as temperature readings, customer information and details of events or product initials. This memory is non-volatile and can retain data even when the device is powered off. Thus, it serves as a low-cost storage solution for today’s most complex embedded applications.

MCP795B21T-I/ST is highly configurable, allowing users to tailor the device to their specific needs. It includes an on-chip programmable frequency output so users can design their own timebase generator that provides a fixed frequency output in order to synchronize other electronic systems.

Overall, MCP795B21T-I/ST Clock/Timing - Real Time Clocks provide a unique feature and benefit set for both designers and batteries. It is a much-needed device for applications that require extended battery life, reliable time management and low power operation. The device is also highly configurable and cost-effective, making it a great choice for low-cost and real-time systems.
