93AA66A-I/MS

Introduction

The 93AA66A-I/MS memory is a Serial Peripheral Interface (SPI) serial EEPROM with 8, 16, 24 or 32 Kbits of organized in 2, 4, 8 or 16 pages of 256 bytes each. It is designed in compliance with the SPI protocol and is optimized for low-voltage and low-power devices.

Application Field

The 93AA66A-I/MS memory offers a wide range of applications in many different fields. It is particularly suitable for storing configuration data, parameters or code in embedded systems, like industrial controllers, home automation, audio systems, medical equipment, portable battery-powered devices, as well as automotive and automotive-related systems.

The 93AA66A-I/MS memory is also suitable for multi-function printers and copiers, where it is used to store various printing profiles, fonts, and other related information. In addition, it is sometimes used in commercial and hobby applications, for instance for storing radio configuration data.

Working Principle

The 93AA66A-I/MS memory works by storing data in its internal memory cells. Data is written or read to/from the memory through a Serial Peripheral Interface (SPI) bus. Each memory location is a byte, so the memory address range is from 0 to 7FFh. The bus speed is up to 20 MHz.

The memory can be configured to use either the 3-wire SPI or the 4-wire SPI bus. Depending on the configuration, additional signals might be required. External logic can be used to control the memory operations, and the memory is capable of programmable power down and reset functions.

The 93AA66A-I/MS series features a range of features including write protection, write status, write status clear, and a Clock out/Slave out pin. The write protection provides a secure environment for data transfer and storage.

Conclusion

The 93AA66A-I/MS memory is ideal for use in many different application fields, including industrial controllers, multi-function printers, and other battery-powered devices. It is designed in compliance with the Serial Peripheral Interface (SPI) protocol, and is optimized for low-voltage, low-power devices. The device features write protection, write status, and write status clear, as well as a range of other features.
