93C46C-I/MS

Introduction

93C46C-I/MS, a 16-bit serial EEPROM, is a product of Microchip Technology. It is used in various applications. It is most commonly used in electronic equipment, including communication systems, computers, automotive systems and medical device communication. This paper discusses the application fields and working principles of 93C46C-I/MS.

Memory Application Fields

The 93C46C-I/MS is used in a wide range of application fields.

• Computer field: It is used as a non-volatile memory for storing configuration data, such as system settings and parameters.
• Communication field: It can be used for storing temporary parameters that needs to be updated from time to time.
• Automotive field: It is used to store configuration data for car door, audio, navigation and engine control systems.

Working Principle

The 93C46C-I/MS utilizes a serial interface called SPI-bus. The use of a serial interface instead of a parallel one simplifies the design of the communication system and helps reduce the number of pins on the IC. The communication between the host device and the 93C46C-I/MS is based on the SPI protocol, which is a synchronous protocol.

The SPI protocol consists of four signal lines: clock (SCLK), slave select (SS/CS), master out-slave in (MOSI) and master in-slave out (MISO). The clock signal is used to keep the operation in synchronization, while the slave select signal is used to choose a particular slave in the system. The MOSI signal is used to transmit the data from the host device to the 93C46C-I/MS, while the MISO signal is used to receive the data from the 93C46C-I/MS.

The 93C46C-I/MS consists of 16 addressable memory locations. Each location can hold a byte of data. The address bus consists of four bits, and the data bus consists of eight bits. The read/write enable control pins are used to control the direction of data flow over the data bus. The write enable control pin is used to enable data writing. If enabled, data from the host device is stored in the specified location. The read enable control pin is used to enable data reading. If enabled, data from the specified location is transferred back to the host device.

Conclusion

The 93C46C-I/MS is a 16-bit serial EEPROM that is widely used in various applications, such as computers, communication systems and automotive systems. It utilizes the SPI protocol to communicate with the host device. Moreover, it consists of 16 addressable memory locations that can each store a byte of data. Through the use of the read/write enable control pins, data can be transferred between the 93C46C-I/MS and the host device.
