Microchip 512 kB EPROM Memory Chip 32-Pin PLCC Package Through Hole Mount AT27C512R-70JU

Microchip AT27C512R-70JU is a 512 kB EPROM memory chip housed in a robust 32-Pin PLCC through hole package. It provides reliable data storage with an OTP (One Time Programmable) reprogramming technique, ensuring that once programmed, the data cannot be erased or altered.

The memory chip features a 64k x 8 bit organization and operates with a parallel interface type, facilitating efficient data communication speeds. It supports a maximum random access time of 70ns, enabling quick memory access suitable for medium-speed applications.

The device operates over a voltage range of 4.5V to 5.5V and can function reliably in temperatures from -40°C to 85°C, making it suitable for industrial and embedded system environments where temperature tolerance is essential.

Its compact physical dimensions of 11.5mm length, 14.3mm width, and 3.37mm height optimize PCB space usage. The total of 32 pins conform to the PLCC package standard, providing secure and stable mounting on through hole PCBs.

This EPROM requires programming before use as it lacks in-system programmability. It is not designed for reprogramming and contains no UV-erasable window, differentiating it from UV-erasable EPROM types. The supply current is approximately 100μA, favoring low power consumption scenarios.

This device is OTP (One Time Programmable), making it suitable for applications where permanent memory storage is required. Parallel interface ensures fast access to memory locations. Wide operating temperature and voltage ranges enhance reliability in various industrial conditions.

Compact PLCC package aids in reducing board space. Low supply current improves energy efficiency in embedded systems. Its 512kB capacity supports sizeable data storage for firmware or configuration settings. Through hole mount style facilitates manual or automated board assembly.

No automotive standards compliance; recommended for general industrial use. OTP nature prevents accidental data modification, ensuring data integrity. Ideal for legacy systems and embedded applications requiring stable non-volatile storage.

Use this Microchip EPROM memory chip in electronic component assemblies, semiconductor applications, industrial electronics, and embedded system designs to provide reliable one-time programmable memory functionality.
