Product Description
Microchip AT27C512R-70PU is a 512 kB One-Time Programmable EPROM memory device packaged in a 28-pin PDIP form factor. It uses a parallel interface optimized for integrated circuit designs where non-volatile memory storage with fixed data is required. The device features a maximum random access time of 70 nanoseconds, making it suitable for fast read applications in embedded systems.
The chip's memory is organized as 64k words by 8 bits, offering a total capacity of 512 kB. It requires a supply voltage between 4.5V and 5.5V, aligning with typical digital logic power requirements. This EPROM uses OTP programming, meaning it can only be programmed once and does not support in-system programmability or erasure.
The 28-pin PDIP package ensures easy integration with through-hole PCB designs, measuring 37.3mm length, 13.9mm width, and 4.8mm height for precise mounting. The operating temperature range of -40°C to 85°C supports deployment in industrial and commercial environments.
The device's supply current is approximately 100 microamperes, enabling efficiency in low power systems. Although no specific industry approvals or automotive certifications apply, its robust design ensures reliable functionality. Manufactured in Thailand, this EPROM is suitable for industrial, laboratory, and embedded electronics applications where permanent non-volatile storage is needed.
The memory size is 512 kB organized as 64k x 8 bits. Reprogramming technique is OTP, supporting one-time programming. Interface type is parallel with 28-pin PDIP package. Operating voltage ranges between 4.5V minimum and 5.5V maximum.
Maximum random access time of 70 nanoseconds provides fast read capability.
This product is ideal for use in embedded electronic devices, industrial controls, instrumentation, and other applications requiring durable, one-time programmable memory. Browse the Electronics & Electricals category on EnvMart to find compatible components and memory solutions.
