Product Description
Microchip AT27C040-70JU is a 4 MB EPROM (Erasable Programmable Read-Only Memory) available in a 32-pin PLCC package, featuring OTP (One-Time Programmable) capability. The device is designed to store 512K words by 8 bits each, providing a reliable memory solution for applications requiring solid-state storage with fast access times of 70 nanoseconds.
This chip utilizes a parallel interface for data transfer and requires a supply voltage between 4.5V and 5.5V. The PLCC 32-pin form factor supports through-hole mounting on printed circuit boards, enabling ease of installation in various electronic designs.
The chip’s OTP technology means it is programmed once and cannot be reprogrammed or erased, making it ideal for permanent data storage. It does not support in-system programmability. Operating temperature ranges from -40°C to 85°C, allowing use in demanding industrial and commercial environments.
The memory chip’s dimensions are compact (11.5mm length, 14.3mm width, 3.37mm height), and it operates with low power consumption at a supply current of 100 microamperes. It does not carry any specific standards or automotive certifications but serves well in semiconductor manufacturing, embedded systems, and electronic component replacement applications.
This EPROM is OTP type, suitable for permanent programming and high data retention. Parallel interface enhances communication speed and reliability. 32-pin PLCC package ensures compatibility with standard sockets and PCBs.
Wide operating temperature range supports industrial and commercial uses. Low supply current reduces overall device power consumption. Compact size facilitates integration into space-constrained designs. Provides 4 MB memory capacity for substantial data storage needs.
Ideal for use in semiconductors, embedded systems, and memory replacement parts.
Microchip products are widely used in industrial automation, electronic instrumentation, and embedded system design. This EPROM supports developers and engineers in creating robust and reliable electronic devices. Check EnvMart categories for more semiconductor and memory chip solutions suitable for your projects.
