M93C46-WDW6TP Application Field and Working Principle

M93C46-WDW6TP is a type of surface mounted device (SMD) Non Volatile Serial Electrically Erasable Programmable Data Memory (EEPROM). It is a memory IC that has been designed by ST Microelectronics. This IC is a low-power, easy-to-use memory device that is ideal for applications that require low-cost nonvolatile data storage.

Application Field

M93C46-WDW6TP is used in a wide range of applications including automotive systems, industrial control, transponder systems, security systems and consumer electronics. The principal application fields of M93C46-WDW6TP include:

• Automotive systems: M93C46-WDW6TP can be used to store vehicle identification data, odometer readings, DTC (diagnostics trouble codes) and other vehicle related data.
• Industrial control: M93C46-WDW6TP can be used to store system configuration information, process control data, and other non-volatile data.
• Transponder systems: M93C46-WDW6TP memory can be used to store authorization codes, frequency information and other data associated with transponder systems.
• Security systems: M93C46-WDW6TP is suited for use in entry systems, access control systems and other security applications.
• Consumer electronics: M93C46-WDW6TP can be used for digital TV remote control devices and other consumer electronics.

Working Principle

M93C46-WDW6TP has a total capacity of 4Kbits or 512 bytes, organized in sixteen pages of 32 bytes each. The serial interface is an eight-line multiplexed bus, which consists of serial data line (SI), serial clock (SK), write enable (WE)/(byte write enable (EWR)) line and data inputs/outputs (DIO). This serial EEPROM is single-power supply and is only two pins wide.

M93C46-WDW6TP adopt 3-wire serial protocol which is the most simple and convenient way of serial data transmission. It utilizes the SI and SK port as the data resource and makes sure the nonvolatile data. The chip has 2 operating modes: write mode and read mode. In write mode, the state of WE port decides whether the bytes can be written and data can also be written by page. The page write mode allows 32 bytes (1 page) of data to be written in one time. In read mode, data can be read out through SI, SK and DIO ports.

M93C46-WDW6TP can also support writing-protection feature, which can prevent data from being updated or damages. It has the feature of data sheet programming which enables the user to write one bit for every write cycle and lock the bits after the programming, thus preventing unauthorized data modification. It also has write-verification which enables the device to verify if data is written correctly.

M93C46-WDW6TP has numerous advantages over other memory devices, such as low power consumption, fast write cycle and write-protection features. It is also ultra-small and can be easily implemented in a wide range of products, making it an ideal solution for applications that require efficient non-volatile data storage.
