The AT28C010-12PI is a high-performance electrically-erasable and programmable read-only memory (EEPROM) integrated circuit from Microchip Technology. This device offers a substantial 1 megabit of memory, providing designers with the flexibility to store large amounts of data in a compact form factor. The part number suffix '12PI' indicates that this EEPROM operates at a speed of 120 ns (nanoseconds) and comes in a PDIP (Plastic Dual In-line Package) format, making it suitable for through-hole PCB mounting.

Designed with reliability and efficiency in mind, the AT28C010-12PI features a parallel interface for high-speed data transfer, allowing for quick and easy access to the stored information. This makes it an excellent choice for applications that require fast data retrieval, such as real-time computing systems and sophisticated industrial controls.

The device operates across a standard voltage range of 5V ± 10%, fitting seamlessly into most existing 5V systems without the need for additional power regulation. It also boasts low power consumption, which is crucial for energy-sensitive applications. The EEPROM's endurance and data retention capabilities are robust, ensuring data integrity over an extended period, even under strenuous conditions.

The AT28C010-12PI is also notable for its user-friendly programming characteristics. It is designed to interface with the industry-standard microprocessors, with no complex programming algorithms required for data write operations. This ease of use extends to the erasure process, which can be accomplished with a simple command sequence, allowing for in-system reprogramming and updates without the need for external programming devices.

This EEPROM's versatility is further enhanced by its hardware features like the chip enable (CE) and output enable (OE) control lines, which provide additional flexibility for system integration. Its robustness, coupled with the manufacturer's commitment to quality, makes the AT28C010-12PI a reliable and cost-effective solution for storing non-volatile data across a wide range of electronic applications.
