Microchip Technology AT27C4096-70PC

The AT27C4096-70PC is a high-performance 4-Megabit OTP (One-Time Programmable) EPROM (Erasable Programmable Read-Only Memory) produced by Microchip Technology. This memory component is designed for applications requiring fast access times and a large non-volatile storage capacity. It is particularly suitable for use in a wide range of industrial, commercial, and consumer products where reliable and durable memory storage is essential.

With a 70 ns access time, the AT27C4096-70PC offers swift read operations, making it an excellent choice for systems that cannot tolerate slow boot or access times. The device is organized as 256K x 16, providing a substantial amount of storage that can be used for code or data that must be preserved when power is removed from the system.

The EPROM operates from a single 5V power supply, making it compatible with many standard digital systems without the need for additional voltage converters. Its low-power consumption makes it an ideal choice for portable and battery-operated applications.

One of the key features of the AT27C4096-70PC is its windowed ceramic package, which allows the stored data to be erased by exposing the die to ultraviolet light. This feature is useful during the development phase when multiple programming cycles might be required. However, once the final code or data has been written, the window can be permanently covered to protect the memory from accidental erasure.

For ease of integration, the AT27C4096-70PC is offered in a 40-pin DIP (Dual In-line Package), which is widely used in the industry and known for its robustness and ease of handling. The device also features high-reliability CMOS technology and has been tested across extended temperature ranges, ensuring performance under various environmental conditions.

In summary, the AT27C4096-70PC from Microchip Technology is a reliable and efficient memory solution for storing large amounts of data in a permanent manner. Its fast access time, large storage capacity, and ease of use make it an attractive option for a multitude of applications that require a dependable non-volatile memory solution.
