Microchip Technology AT28C64-20SC EEPROM

The AT28C64-20SC is a high-performance, 64-Kilobit parallel EEPROM designed and manufactured by Microchip Technology. This non-volatile memory chip is ideal for applications that require data storage that must be preserved during power loss. With its 8K x 8 organization, the AT28C64-20SC provides ample storage for firmware storage, configuration parameters, and data logging in a variety of systems.

This EEPROM operates at a speed of 200ns (nanoseconds), ensuring quick data access and high-speed read operations, which is critical for performance-sensitive applications. The device is also characterized by its low-power consumption, making it suitable for battery-operated and power-conscious designs.

The AT28C64-20SC is packaged in a 28-lead SOIC (Small Outline Integrated Circuit) package, which allows for a compact footprint on printed circuit boards. It also features a simple byte and page write operation, which is both convenient and efficient, as it allows for 1 to 64 bytes of data to be written in a single write cycle, reducing overall programming time.

One of the key advantages of the AT28C64-20SC is its hardware data protection feature. The device includes a hardware and software data protection scheme designed to prevent inadvertent writes to the memory during power-up, power-down, or system reset, ensuring the integrity of the data stored within.

The AT28C64-20SC is also versatile in terms of its compatibility with different microprocessor systems. It supports rapid programming algorithms and has an industry-standard parallel interface, which makes it easy to integrate into existing designs without the need for significant re-engineering.

Overall, the Microchip Technology AT28C64-20SC EEPROM is a reliable and efficient solution for designers looking to add non-volatile memory to their electronic designs. Its combination of speed, low power consumption, data protection features, and ease of integration make it a smart choice for a wide range of applications.
