As shown, it consists of EEPROM 24C256 and calendar clock chip PCF8563. The 24C256 is a low voltage, serial interface with a 256K memory for storing measured blood pressure values. The PCF8563 is an industrial grade I2C bus with a very low power consumption multifunction clock/calendar chip from PHILIPS. It is used to provide the time and date when blood pressure is measured for later use. It is convenient for users to have a clear memory of their blood pressure for a period of time. Practicality, overcoming the shortcomings of some electronic sphygmomanometers.

Circular Connectors
Circular connectors, also called [circular interconnects," are cylindrical, multi-pin electrical connectors. These devices contain contacts that transmit both data and power. Cannon (now ITT Tech Solutions) introduced circular connectors in the 1930s for applications in military aircraft manufacturing. Today, you can find these connectors in medical devices and other environments where reliability is essential.
Circular Connectors is designed with a circular interface and housing to quickly and easily connect and disconnect signal, power, and optical circuits. Circular connectors are often preferred in military, aerospace, and industrial applications: these can be connected and disconnected without the use of coupling tools such as torque wrenches. Antenk`s circular connectors offer rugged solutions that have been engineered for reliable performance in a wide variety of harsh environment applications.
I/O connectors provide secure electrical contact and smooth, safe disconnect. They are used across a range of industries for communications devices, business equipment and computers. Top considerations when purchasing I/O connectors include pinout, gender, voltage rating, contact plating, and termination style.
Types of Circular Connectors
Circular connectors typically feature a plastic or metal shell surrounding the contacts, which are embedded in insulating material to maintain their alignment. These terminals usually pair with a cable, and this construction makes them especially resistant to environmental interference and accidental decoupling.
