93C86A-I/ST

The 93C86A-I/ST is a type of memory device. It is a serial CMOS EEPROM (Electrically Erasable Programmable Read-Only Memory) which is capable of being addressed and programmed via a serial interface. The device is ideal for a wide range of applications, from secure data storage in secure access devices to the storage of important system parameters in computers and embedded systems.

The 93C86A-I/ST employs a static random-access memory (SRAM) cell array technology and has a wide temperature range of -40°C to +85°C, making it suitable for a variety of harsh conditions. It has a number of pin configurations and two write cycle times available to meet the needs of various applications.

The 93C86A-I/ST has a few different methods of programming and works well with various combination of software and hardware. The device has an 8-bit parallel Write Mode, 2-wire Serial Mode, 4-wire Serial Mode, and a Combined Mode. In addition, for the 8-bit parallel Write Mode, the device supports an external clock or timing generation. The level of the external clock must be compatible with the device.

The 8-bit parallel Write Mode of the 93C86A-I/ST is the most widely used programming method. This mode allows for rapid programming as the data is written to the device in a parallel fashion. This is accomplished by presenting an 8-bit data word on the Data Input pins and then applying a high level write pulse to the write terminal. For writing more than eight data bytes to the device, multiple write cycles are necessary. In addition, the 8-bit parallel Write Mode supports an external clock. The timing of the output data is determined by a low-to-high transition of the write clock. Thus, devices with no internal clock source can be programmed very easily.

The 2-wire Serial Mode allows the transfer of serial data to and from the device, while the 4-wire Serial Mode gives greater freedom in the timing of the serial data transfers, making it a preferred method for certain applications. The Combined Mode is a combination of the 8-bit parallel Write Mode and the 4-wire Serial Mode and is utilized for certain secure data storage applications, where data security is paramount.

The 93C86A-I/ST is versatile and can be used in a broad range of applications. It is well suited for secure data storage, where data confidentiality is a key consideration. The device can be used for protecting secure data stored in a wide range of security systems, from access control systems to biometric identification or simply for storing application parameters where secure data encryption and secure operation are the top priority.

The 93C86A-I/ST is also commonly used in automotive, industrial, medical, and telecommunications applications, and is employed in various products ranging from automobile navigation systems to medical and home automation systems. The device is also a great option for storing system parameters in embedded systems and computers.

The 93C86A-I/ST is an excellent and reliable choice for a variety of memory device applications. It is a dependable serial CMOS EEPROM with multiple write cycle times, a wide temperature range, and several programming methods that can be tailored to meet the needs of various applications. The device is ideal for secure data storage and a variety of specialized applications.
