AT28C64X-20JC

AT28C64X-20JC is a type of memory integrated circuit. It is widely used in computers. It is also used in consumer electronics and vehicles, as well as in industrial aerospace and telecommunication applications.

AT28C64X-20JC has an 8K bit static RAM, an 8K bit EPROM, a POR, an outputenable and a write enable. It is a bipolar memory integrated circuit which combines an 8K bit EPROM and 8K bit SRAM in an 8-pin package. It is fabricated with a CMOS process that combines EPROM, RAM, and POR circuits into a single chip. The CMOS technology offers consumption and high speed write operations for higher system performance.

The static RAM is used for data storage, while the EPROM is used for memory storage. The POR (power on reset) ensures that all the memory contents are retained when the power is ON, and the output-enable ensures that the data is not overwritten or erased during write operations. The write enable indicates when a write operation is in progress.

AT28C64X-20JC works by retrieving and storing data in the EPROM and RAM. Data is retrieved from the EPROM through the address line, while the data is retrieved from RAM via a write operation. The data is then stored on the EPROM when the write enable is activated.

The AT28C64X-20JC has a read cycle time of 120ns, a write cycle time of 120ns, and an endurance rating of 200,000 cycles. The device is supported by a number of operating systems including Windows 98/2000/NT/XP, Linux, Mac OS9, SunOS, and others. It supports SPI and I2C data transfer protocols.

The AT28C64X-20JC memory integrated circuit is a highly reliable storage device, with the ability to meet the needs of the most complex applications. It is widely used in consumer electronics, industrial aerospace and telecommunication applications.
