Microchip Technology 27C64 EPROM
The 27C64 is a high-performance, 64-Kilobit (8K x 8) UV erasable and programmable read-only memory (EPROM) device produced by Microchip Technology. It is a versatile and reliable memory component, widely used in the storage of firmware and software in various electronic systems. The 27C64 is designed for applications that require fast read access and data stability over an extended period.
Featuring a fast access time of as low as 150 nanoseconds, the 27C64 allows for quick data retrieval, enhancing the overall performance of systems it is integrated into. Its compatibility with industry-standard microprocessor buses makes it a suitable choice for a wide range of applications in the computing, automotive, telecommunications, and consumer electronics industries.
The device is organized as 8,192 words by 8 bits, which allows for a substantial amount of data to be stored. It comes in a 28-pin dual in-line package (DIP) that includes a quartz window, through which the silicon chip is exposed to ultraviolet light for erasure. The programming of the 27C64 is performed in a byte-by-byte or word-by-word fashion, which provides designers with flexibility in data management.
The 27C64 also features programmable chip enable and output enable controls, which provide system-level control over the EPROM's operations. This ensures that data integrity is maintained during system power-up and power-down cycles. The product operates within a single 5V power supply, which simplifies the power design of the overall system.
Microchip Technology's commitment to quality means the 27C64 is manufactured to high standards, ensuring its reliability and longevity in the field. Its UV erasable nature allows the device to be reused, which can be particularly advantageous during the development and testing phases of a product.
Overall, the 27C64 EPROM from Microchip Technology stands out as a solid choice for designers looking for a dependable and flexible non-volatile memory solution.
