Memory is an essential component in the design of computing systems. AT93C86A-10PU-2.7, as a kind of Memory, is commonly used in applications such as automotive and industrial systems. In this article, AT93C86A-10PU-2.7’s application field and working principle will be explained in detail.

AT93C86A-10PU-2.7 is a nonvolatile 8-Kb Serial CMOS EEPROM device organized as 128 pages of 64 bytes each. It is designed for use in multiple-access applications such as automotive and industrial systems, which require tremendous amount of data storage and communication protocol. As a standard EEPROM device, AT93C86A-10PU-2.7 provides 1,048,576 bits of Serial Peripheral Interface (SPI) EEPROM memory, which is organized as 128 pages of 8 bits each.

The device provides a 16-bit address space and is capable of random, page write/erase, multi-byte operations as well as simultaneous read and write operations, making it an ideal solution for multiple access applications. It features a low-power consumption (1 mW at 5 VCC and 10 kΩ in order to guarantee data retention of 10 years), a fast page access time (30 Вµsec) and a low standby current (3.6 ВµA). In addition, it features a hardware write-protect pin, which allows the devices to be put in write-protected mode.

The AT93C86A-10PU-2.7 memory device is designed to operate in either a serial or parallel mode. The serial mode (or SPI) uses a chip-select (CS), serial clock (SCLK), data out (DO), and data in (DI) interface signals. In the parallel mode, an additional 9-bit data bus is used. Both modes provide an 8-bit data register. The SPI mode provides a full-duplex Serial Peripheral Interface (SPI) for maximum compatibility with parent processor units.

The AT93C86A-10PU-2.7 device supports two distinct write modes. The Standard (Byte-Write) mode allows single bytes of data to be written within the page. A page write consists of 64 bytes within one page, with each byte specified by its address. The Fast Page-Write mode allows data to be written within a page in larger blocks (up to page size), with all the data in the page written in the same cycle.

The AT93C86A-10PU-2.7 operates with a single power supply ranging from 2.7V to 5.5V. The device provides low-power consumption, high-reliability, and a long data retention time. In addition, the device provides global write-protect pin and write/erase status bits to track the status of the erase and write cycles.

In summary, AT93C86A-10PU-2.7 is a nonvolatile 8-Kb Serial CMOS EEPROM device, featuring low-power consumption, fast page access time, low standby current and a long data retention time. The device provides random access, multi-byte operations, simultaneous read and write operations. It is designed for automotive and industrial systems, and can be operated in either SPI mode or parallel mode, providing a full-duplex SPI interface. This comprehensive set of features makes AT93C86A-10PU-2.7 a reliable and effective memory solution for multiple access applications.
