M24C02-FMC6TG Application Field and Working Principle

Introduction

M24C02-FMC6TG is a dual-channel serial EEPROM memory for I2C-bus applications.This device is suited for applications requiring a small amount of NVRAM (Non-Volatile Random Access Memory) such as an configurable objects and write-once, read-many data elements. It provides an 8-pin dual-channel EEPROM package with an internal 256-byte data buffer. The device uses the I²C-bus protocol and is identified by the fixed address.

Application field

M24C02-FMC6TG memory is predominantly used in industrial and automotive applications. It is used as a solution for a wide range of in-circuit memory requirements, including application parameter settings and write-once product identification codes and system setup data. In automotive applications, the M24C02-FMC6TG is mainly used for key-less entry systems and door access control. In industrial and medical applications, applications include core ID systems that store and verify the product identity, serial number, and setup parameters. Typical applications are product authentication, customer specific serial numbers, production data for input/output control, product configuration, data logging, and product code assignment. The M24C02-FMC6TG memory is also used in a variety of consumer applications such as audio and video equipment, digital still cameras, camcorders, and extended temperature ranges.

Working Principle

The M24C02-FMC6TG memory has a typical byte access time of 3.5 ms. It is a non-volatile memory that requires no refresh cycles. The device can be programmed byte by byte and accessed randomly in random access read/write mode (R/W). Additionally, it is protected against code corruption caused by stray electrical fields, so it is resistant to noise. The device supports the I²C-bus protocol. The protocol includes an acknowledge function and indicates that the transmitted data has been received by the bus slave (the memory). The lower seven bits of the I²C-bus address define the device specific address, so up to eight devices can be connected to the bus. The M24C02-FMC6TG device stores up to 256 bytes of user-defined data in memory. Data can be programmed by supplying data and the corresponding address over the I²C-bus to the device. The device has the following additional features: EEPROM write protect (WP) and Page Write protection (PW). The WP pin is used to turn off the write function of the EEPROM, allowing the programming of the content of memory without disturbing the code. The PW pin allows the user to write-protect a 128 byte page or word. The device has an internal single bit latch for each byte that can be used for write protection.In conclusion, M24C02-FMC6TG memory is designed for industrial and automotive applications that require data storage and verification. This device is widely used in industrial and medical applications, as well as consumer applications such as audio and video equipment, digital still cameras, and camcorders. Furthermore, the device is used in extended temperature ranges, and offers an 8-pin dual-channel EEPROM package. It supports the I²C-bus protocol and stores up to 256 bytes of user-defined data in memory.
