The part number M24C04-WMN6TP seems to belong to STMicroelectronics. Specifically, this part is a 4Kb I2C EEPROM.Package Type
The M24C04-WMN6TP typically comes in a SO8 package, which is a small outline IC package with 8 pins. This is a common package for EEPROM and other small-scale ICs.Pinout and Function Descriptions
The M24C04-WMN6TP has 8 pins, and here's a detailed breakdown of their functions:
Pin Number Pin Name Pin Function Description 1 A0 Address pin for addressing multiple devices on the I2C bus (used in multiple EEPROMs). 2 A1 Address pin for addressing multiple devices on the I2C bus (used in multiple EEPROMs). 3 SDA Serial Data Input/Output: I2C data line used for communication between devices. 4 SCL Serial Clock Input: I2C clock line used for synchronization of data transfer. 5 VSS Ground: Provides the reference ground for the circuit. 6 VCC Power Supply: Typically 2.5V to 5.5V, used to power the EEPROM. 7 WP Write Protect: This pin is used to protect the EEPROM data from accidental writes. 8 NC No Connection: This pin is not internally connected and is reserved for future use.Circuit Principle
The M24C04-WMN6TP is an EEPROM ( Electrical ly Erasable Programmable Read-Only Memory ) that communicates with microcontrollers via the I2C bus. The EEPROM stores data in a non-volatile memory, meaning it retains data even when power is removed. SDA (Serial Data Line) and SCL (Serial Clock Line) are the key I2C interface pins that allow data to be read and written. Data is transferred in byte-form, and the clock (SCL) synchronizes the data flow. VSS is the ground, while VCC provides the power necessary to operate the chip. A0 and A1 are used for selecting one of several devices if multiple EEPROMs are connected to the same I2C bus. WP provides write protection for the memory, which prevents accidental data writes.Frequently Asked Questions (FAQ)
1. What is the part number of the EEPROM? The part number of the EEPROM is M24C04-WMN6TP. 2. What is the EEPROM's communication protocol? The M24C04-WMN6TP uses the I2C communication protocol for data transfer. 3. How many pins does the M24C04-WMN6TP have? The M24C04-WMN6TP has 8 pins. 4. What is the maximum voltage for the VCC pin? The maximum voltage for the VCC pin is typically 5.5V. 5. What is the minimum voltage for the VCC pin? The minimum voltage for the VCC pin is typically 2.5V. 6. Can I use the M24C04-WMN6TP with 3.3V? Yes, the M24C04-WMN6TP is compatible with 3.3V systems, as long as the voltage stays within the 2.5V to 5.5V range. 7. What happens if I do not connect the WP pin? If the WP (Write Protect) pin is not connected, the EEPROM is not write-protected, and it is vulnerable to accidental writes. 8. What is the function of the A0 and A1 pins? The A0 and A1 pins are used for addressing multiple EEPROM devices on the same I2C bus. 9. Can I connect multiple M24C04-WMN6TP devices to the same I2C bus? Yes, by using different combinations of the A0 and A1 pins, multiple devices can be connected to the same I2C bus. 10. What is the data storage capacity of the M24C04-WMN6TP? The M24C04-WMN6TP has a 4Kb (kilobits) storage capacity. 11. Is the M24C04-WMN6TP capable of high-speed data transfer? The M24C04-WMN6TP supports standard I2C speeds (100kHz to 400kHz) for data transfer. 12. What is the power consumption of the M24C04-WMN6TP? The power consumption is very low in standby mode, typically in the microampere range. 13. What is the write endurance of the EEPROM? The M24C04-WMN6TP typically has a write endurance of 1 million write cycles. 14. How do I read data from the M24C04-WMN6TP?
