IC EPROM 512KBIT PARALLEL 32PLCC
Stock Quantity: 0
The AT27C512R-70JU is a 512-kilobit (64K x 8) electrically programmable read-only memory (EPROM) integrated circuit manufactured by Atmel. This device features a parallel interface for data access and programming, enabling high-speed read operations. Organized as 65,536 bytes, it operates from a single 5V power supply and is housed in a 32-pin Plastic Leaded Chip Carrier (PLCC) package, suitable for surface mount assembly. The -70 suffix designates a maximum access time of 70 nanoseconds, indicating its suitability for applications demanding rapid data retrieval. Programming is achieved via application of a higher voltage to specific pins, allowing for erasure and reprogramming cycles. The device is typically used for storing firmware, boot code, and other non-volatile data in embedded systems.
