Memory: 93LC66BT-E/MS Application Field and Working Principle

The 93LC66BT-E/MS is a 2K bit Microwire Serial EEPROM designed for use inemerging digital systems and applications where low power dissipation, spaceefficiency and high speed data communication are critical. With atremendous amount of technology advancements, this EEPROM brings aboutsignificant improvements, both in terms of cost and performance, in thememory market.

The 93LC66BT-E/MS, which can be employed in either Flash EEPROM orElectrically Erasable Programmable Read-Only Memory (EEPROM) applications,utilizes Microwire Serial interface protocol to transfer and receive data.It is composed of Flip-chip, Plastic Ball Grid Array (PBGA) andThin-Body Small Outline Package (TSOP) technologies, among others.

Applications of 93LC66BT-E/MS

93LC66BT-E/MS is suitable for various applications where a non-volatilememory is required. It can store and retrieve information in small,low-power portable devices, such as digital cameras, digital videorecorders, cell phone handsets, MP3 players, digital recorders andpersonal digital assistants (PDA). They are also suitable for controllingmicroprocessor parameters and small scale interface communication systems.The 93LC66BT-E/MS can be used for large scale systems where largevolumes of data need to be stored, such as in digital metering systems,factory automation systems, plant monitoring systems or digital assetmanagement systems.

Working Principles

The 93LC66BT-E/MS is controlled by the Microwire Serial interfaceprotocol. This protocol consists of an 8-bit command byte followed byoptional data bytes. All the data is sent and received through the SerialData Input/Output (SDI/SO) pins. The 93LC66BT-E/MS supports twodifferent types of commands; instruction and data. Instruction commandsinclude READ, WRITE, ERASE and TURN ON/OFF. The WRITE instruction commandwill start a write operation by setting up the circuitry required for thewrite operation. The ERASE instruction command will erase the entirememory in just 5 microsecond. The TURN ON/OFF command will enable anddisable the write mode.The data commands are used for communication between the EEPROM and thehost device. These commands can be used to read or write the data fromor to the EEPROM. The READ command will read the data from the EEPROMto the host device and the WRITE command will write the data from thehost device to the EEPROM.

Conclusion

The 93LC66BT-E/MS is an efficient and cost-effective solution forstoring and retrieving data in microprocessor based applications. Withits advanced technologies, the 93LC66BT-E/MS provides a non-volatilememory solution which is both reliable and power efficient.
