To create a high level block diagram for U3, which is a DS3231 AT24C32 module by BanKhok, I'll illustrate the primary components and connections based on the description. The DS3231 AT24C32 module integrates a real-time clock (RTC) and an EEPROM (AT24C32) into one module. This combination makes it a compact solution for time-keeping and data storage applications.
Diagram
A: DS3231 AT24C32 Module: This is the core component which houses both the RTC and EEPROM functionalities.
B: RTC (DS3231): This is the real-time clock component of the module, providing accurate timekeeping.
D: VCC: Power supply for the RTC.
E: GND: Ground connection for the RTC.
F: SCL: Serial Clock Line for I2C communication for the RTC.
G: SDA: Serial Data Line for I2C communication for the RTC.
L: 32K Output: 32kHz Output.
M: SQW Output: Square Wave Output.
C: EEPROM (AT24C32): This is the electrically erasable programmable read-only memory that provides 32Kb of storage space.
H: VCC: Power supply for the EEPROM.
I: GND: Ground connection for the EEPROM.
J: SCL: Serial Clock Line for I2C communication for the EEPROM.
K: SDA: Serial Data Line for I2C communication for the EEPROM.
This basic block diagram illustrates how the components within the U3 module are interconnected and their main functions. The DS3231 provides precise time-tracking capabilities, while the AT24C32 offers non-volatile storage for application data. Both components utilize the I2C bus for communication, simplifying the integration into larger systems.
