Product Description
Microchip AT27C4096-55JU is a 4 MB EPROM memory chip in a 44-pin PLCC package featuring parallel interface and OTP (One Time Programmable) technology with a maximum random access time of 55ns. Designed for applications requiring reliable memory storage, this chip is ideal for industrial, electronics development, and embedded systems.
This EPROM device contains 256K words with 16 bits each, providing ample memory capacity in a compact form factor. Its OTP architecture means it cannot be erased or reprogrammed once programmed, ensuring stable data retention and security.
Operating voltage range is set between 4.5V minimum and 5.5V maximum, making it compatible with standard 5V logic systems. The chip's operating temperature spans from -40°C to 85°C, supporting industrial-grade temperature requirements.
The PLCC 44-pin package supports through-hole mounting and measures 16.6mm by 16.6mm by 4.4mm, allowing efficient placement on printed circuit boards with limited space. The power consumption is optimized with a 100 μA supply current, suitable for low-power applications.
This component does not feature in-system programmability, so programming must be done prior to assembly. Not certified with additional standards or automotive grade but manufactured to reliable quality suitable for multiple electronics sectors.
This EPROM chip has a memory size of 4MB organized as 256 k x 16 bits. The one-time programmable architecture secures data integrity after programming. Package type is PLCC with 44 pins for through-hole mounting. Operating voltage range is 4.5V to 5.5V with low supply current of 100 μA.
Designed to operate over a temperature range of -40°C to 85°C. Dimensions of 16.6mm length, 16.6mm width, and 4.4mm height. No in-system programmability is supported.
Commonly used in industrial automation, embedded systems, and electronics manufacturing for stable and secure memory requirements. For more semiconductor products and memory chip options, browse the Electronics & Electricals category at EnvMart.
