PCF8563MDTR

The PCF8563MDTR is a low-power CMOS real-time clock/calendar chip produced by NXP Semiconductors (formerly Philips Semiconductors). While “MDTR” is not a standard suffix or terminology associated with the PCF8563, it could potentially refer to a specific version, package type, or additional features of the chip. However, due to the lack of a direct reference to “MDTR” in relation to the PCF8563 in standard documentation, the following description focuses on the general characteristics and features of the PCF8563, which are likely to be applicable to any variant, including the hypothetical PCF8563MDTR.

Key Features and Specifications

• Low Power Consumption: The PCF8563 is designed for low power applications, with a typical backup current of 0.25μA at VDD = 3.0V and Tamb = 25°C. This makes it suitable for battery-powered devices.
• Wide Operating Voltage Range: The chip operates within a wide voltage range of 1.0V to 5.5V, providing flexibility in power supply design.
• Real-Time Clock/Calendar Function: The PCF8563 provides accurate time and date information, including seconds, minutes, hours, days, months, years, and even a century flag for century-based dating.
• Alarm and Timer Functions: It supports multiple alarm settings and timer functions, allowing for flexible scheduling and event triggering.
• Programmable Clock Output: The chip offers programmable clock outputs at frequencies such as 32.768kHz, 1024Hz, 32Hz, and 1Hz, suitable for various peripheral devices.
• Interrupt Output: An open-drain interrupt pin is provided, which can be used to generate interrupt signals for external processing when specific events occur, such as alarms or timer expiration.
• I²C Bus Interface: The PCF8563 communicates with the host system via the I²C bus interface, which supports standard-speed (100kbps) and low-speed (10kbps) modes. This simplifies system design and integration with other microcontrollers.

Package and Applications

• Package Types: Depending on the specific variant (e.g., PCF8563MDTR), the chip may be available in different package types such as DIP8, SO8, or SOIC-8. These packages are designed to fit various application requirements and board layouts.
• Applications: The PCF8563 is widely used in various electronic devices that require precise time management, including embedded systems, consumer electronics, industrial controllers, mobile phones, portable instruments, and battery-powered products.

Additional Notes

• While “MDTR” is not a standard terminology for the PCF8563, it could potentially refer to a specific version or variant of the chip with additional features or optimizations. Therefore, it is important to consult the official documentation or contact the manufacturer for accurate information about the PCF8563MDTR (if it exists).
• In general, the PCF8563 is a reliable and versatile real-time clock/calendar chip that offers a combination of low power consumption, wide operating voltage range, and flexible features. It is well-suited for a wide range of applications that require accurate timekeeping and event scheduling.
