Product Description
Microchip AT27C256R-70JU is a 256 kB One Time Programmable (OTP) Erasable Programmable Read-Only Memory (EPROM) device housed in a 32-pin Plastic Leaded Chip Carrier (PLCC) package. Designed for through-hole mounting, this memory chip offers a parallel interface and fast maximum random access time of 70 nanoseconds, making it suitable for diverse electronic applications.
This EPROM is programmed once and cannot be erased due to the absence of a UV erase window, ensuring data permanence and reliability. It operates within a supply voltage range of 4.5 V to 5.5 V and supports operational temperatures ranging from -40°C to 85°C, making it adaptable for industrial and commercial electronic systems.
With a memory organisation of 32K words by 8 bits and a low supply current of 100 μA, it is energy efficient and appropriate for embedded system designs where space and power savings are critical. The compact dimensions of 11.5 mm x 14.3 mm x 3.37 mm provide ease of integration on boards with limited space.
This product meets no specific automotive or approval standards but is suitable for industrial, manufacturing, and electronic engineering projects requiring lasting programmable memory.
Memory size of 256 kB organised as 32K x 8 Bit. Parallel interface for fast data exchange. One Time Programmable OTP device for permanent memory storage. Through-hole PLCC package with 32 pins. Operating voltage from 4.5 V to 5.5 V.
