The 93C86BT-I/SN is a typical serial EEPROM that belongs to the memory category. It has a wide range of applications and is an important component for many devices. In this article, we will discuss the features, applications and working principles of the 93C86BT-I/SN.

Features of the 93C86BT-I/SN

The 93C86BT-I/SN is a serial static random access memory (SRAM) manufactured by STMicroelectronics. It has 1024 bits of memory, 16 bytes of memory in each device, and capabilities for address and data protection. It is constructed with a CMOS technology for superior performance at low power consumption. It operates with a single power supply voltage of 2.7 V to 5.5 V or 3 V to 5.5 V. Its standby current consumption level is extremely low, around 10microamperes. It also offers higher write speeds than other stand-alone serial EEPROMs.

Applications of the 93C86BT-I/SN

The 93C86BT-I/SN is suitable for many applications, including digital audio players, PDAs, automotive systems, light toys, games, and other data storage products. It is used in industrial applications such as power supplies, analysers and sensors. It is also used in medical products, including electronic thermometers, pulse oximeters, and blood pressure monitors. It can be used as a non-volatile memory to store configuration settings, application parameters and other small data that needs to be accessed quickly and occasionally written to.

Working Principle of the 93C86BT-I/SN

The 93C86BT-I/SN is an electrically erasable and programmable read only memory (EEPROM). It uses a simple serial interface that is compatible with microcontroller systems as well as other serial EEPROMs. It has self-timed write cycles for data storage and protection. A strobe signal and two address bits are sent during the write cycle, and the memory is written byte by byte. It uses two-wire serial data transmission according to the industry-standard two-wire protocol.

Read cycle operation is similar to write cycle. First, the two address bits are transmitted by the microcontroller, followed by the read command and a strobe signal. The desired data is then outputted through the serial interface. The microcontroller receives the data and stores it to enable online data verification and secure data integrity. The 93C86BT-I/SN also has an erase cycle which erases all data in the memory by sending a three-byte erase command.

The 93C86BT-I/SN has some protection features such as write-protect, write-only and password lock. write-protect and write-only protect the user from accidental writes and erases by disabling the write and erase cycles. Password lock enables content protection and secure operations by preventing access to the memory until the correct password is entered.

Conclusion

The 93C86BT-I/SN is a versatile and reliable serial EEPROM suitable for many applications. It has a wide operating voltage range and low power consumption, as well as fast write and erase cycles. It has a variety of protection features to prevent accidental writes and erases, and it can also be password protected. With these features, the 93C86BT-I/SN is an ideal memory component for various digital audio, automotive and medical products.
