Categories: EEPROMs

Quality Control: Learn More

The Microchip Technology AT28HC256-12FM is a 262,144-bit (32K x 8) parallel interface, high-speed CMOS Electrically Erasable Programmable Read-Only Memory (EEPROM). This component features a 120ns access time and supports asynchronous operation. It offers a data retention endurance of 10,000 write cycles. The AT28HC256-12FM includes automatic write and data polling capabilities, along with a toggle bit for status indication. Designed for robust performance, it operates within a temperature range of -40°C to +85°C and requires a supply voltage of 4.5V to 5.5V. The device is available in a 28-lead Ceramic Dual Flat Pack (CDFP28) package, conforming to MIL-STD-883 Class B screening standards. This memory solution is suitable for applications in industrial control, aerospace, and defense systems requiring reliable non-volatile data storage.

Integrated Circuit FAQs

An integrated circuit (IC) is a semiconductor chip that contains transistors, resistors, capacitors, and other electronic components on a single silicon substrate. ICs are the foundation of modern electronics and power devices such as smartphones, computers, automotive systems, and industrial equipment.

Integrated circuits work by routing electrical signals through microscopic semiconductor components fabricated onto a silicon chip. Depending on the design, ICs can process, amplify, store, or control electronic data.
