PCF8563DTR

The PCF8563DTR, though not explicitly mentioned in the sources provided as a distinct variant, can be generally described based on the information available for the PCF8563 family of real-time clocks (RTCs) from NXP Semiconductors. Here’s a detailed description in English:

PCF8563DTR Description

The PCF8563DTR (or potentially a variant within the PCF8563 family, as “DTR” might denote a specific packaging or configuration) is a CMOS-based Real-Time Clock (RTC) and calendar designed for low power consumption. It is optimized for applications where power efficiency is critical, such as mobile telephones, portable instruments, electronic metering, and battery-powered products.

Key Features:

1. Low Power Consumption: The PCF8563DTR is designed to consume minimal power, making it ideal for battery-powered devices.
2. Real-Time Clock and Calendar: It provides accurate time and date information, including year, month, day, weekday, hours, minutes, and seconds.
3. Programmable Clock Output: The device offers a programmable clock output for peripheral devices, with options such as 32.768 kHz, 1024 Hz, 32 Hz, and 1 Hz.
4. Interrupt Output and Voltage-Low Detector: An interrupt output is provided for alerting the host system when a specific event occurs, such as an alarm or timer trigger. Additionally, a voltage-low detector monitors the power supply and can trigger an interrupt if the voltage drops below a certain threshold.
5. I2C-Bus Interface: The PCF8563DTR communicates with the host system via a two-wire bidirectional I2C-bus interface, with a maximum bus speed of 400 kbits/s. This allows for easy integration with microcontrollers and other I2C-compatible devices.
6. Built-In Oscillator and Divider: The device includes an integrated 32.768 kHz oscillator and a divider to provide the necessary clock signals for the RTC and calendar functions.
7. Wide Operating Voltage Range: The PCF8563DTR operates within a wide supply voltage range, typically from 1.0 to 5.5 V, providing flexibility in power source selection.
8. Alarm and Timer Functions: The RTC includes alarm and timer functions that can be configured to trigger at specific times or intervals.
9. Package Options: Depending on the specific variant (e.g., PCF8563T, PCF8563TS, etc.), the device is available in various package options such as SO8, TSSOP8, and others, allowing for flexibility in PCB layout and design.

Applications:

• Mobile Telephones
• Portable Instruments
• Electronic Metering
• Battery-Powered Products

Note:

While the specific suffix “DTR” is not explicitly mentioned in the sources provided, it is likely a reference to a particular packaging or configuration within the PCF8563 family. Therefore, it is important to consult the official datasheet or contact NXP Semiconductors for detailed information on any specific variant.

In summary, the PCF8563DTR (or its equivalent variant within the PCF8563 family) is a highly versatile and efficient RTC and calendar solution suitable for a wide range of low-power applications.
