Product Description
Microchip AT27C020-55JU is a 2 MB One Time Programmable (OTP) EPROM memory device housed in a 32-pin PLCC package with through-hole mount. This parallel interface memory offers 256k x 8 bit organization and a maximum random access time of 55ns, ensuring fast and reliable read performance.
Operating with a supply voltage range from 4.5V to 5.5V and low supply current of approximately 100μA, it supports a wide operating temperature range of -40°C to 85°C, making it suitable for industrial and commercial electronic circuits requiring robust and stable memory solutions.
The EPROM is programmed once and cannot be erased due to absence of a window in the package, eliminating reprogramming possibilities. This feature is ideal for applications where permanent data storage is necessary.
Its compact dimensions of 11.5mm length, 14.3mm width, and 3.37mm height enable space-efficient integration into circuit boards. The 32-pin PLCC package facilitates secure through-hole mounting.
2 MB Memory capacity organized as 256k x 8 bits. Maximum random access time of 55 nanoseconds. Operates with low 100μA supply current. Range of supply voltage from 4.5V to 5.5V. Operating temperature range is -40°C to 85°C.
One-time programmable; non-erasable. 32-Pin PLCC package with through hole mount. Compact dimensions suitable for dense PCB layouts.
This EPROM memory device is widely used in industrial electronics, communication equipment, instrumentation, and embedded systems requiring stable, permanent firmware or data storage. Its OTP technology ensures data integrity where rewriting or erasing is not desirable.
