Product Description
Microchip AT27C512R-70PU is a 512 kB EPROM (Erasable Programmable Read-Only Memory) memory chip housed in a 28-pin PDIP package designed for through-hole mounting. It offers a one-time programmable (OTP) reprogramming technique, making it suitable for applications requiring permanent stored data that doesn't need erasing.
This EPROM device uses a parallel interface and provides a maximum random access time of 70ns, enabling efficient read speeds in embedded systems, industrial electronics, and other electronic equipment. The memory organization is 64k words by 8 bits, allowing for robust data storage capacity.
Designed to operate within a supply voltage range of 4.5V to 5.5V, this chip draws a low operating current of 100μA, contributing to energy-efficient designs. It functions reliably across a wide temperature range from -40°C to 85°C, making it suitable for harsh industrial and automotive environments.
The chip's physical dimensions measure 37.3mm in length, 13.9mm in width, and 4.8mm in height, conforming to PDIP standards for easy PCB integration with standard sockets. The absence of a UV-erasable window indicates that the chip cannot be erased or reprogrammed once programmed, ensuring data permanence.
Microchip's AT27C512R-70PU EPROM is an ideal component for industrial, manufacturing, electronic prototype, and legacy system applications where reliable, permanent, and fast-read memory storage is required without the need for future modification.
This EPROM supports OTP programming acting as a permanent memory solution. Parallel interface ensures compatibility with common microcontrollers and systems. Wide temperature tolerance suits industrial and harsh environments.
Low power consumption enhances device energy efficiency. Robust 28-pin PDIP package for easy mounting and replacement. The chip is non-volatile memory holding data without power supply.
