Product Description
Microchip AT27C020-90JU is a high-reliability 2 MB One-Time Programmable (OTP) EPROM memory chip featuring a parallel interface and housed in a 32-pin Plastic Leaded Chip Carrier (PLCC) package. This memory device provides permanent data storage suitable for applications that require non-volatile storage with one-time programming capability.
The memory organization of 256k x 8 bits delivers 2 megabits of storage. It operates within a supply voltage range of 4.5 to 5.5 volts, making it compatible with standard 5V logic systems. The device's maximum random access time is 90 nanoseconds, ensuring efficient and fast read operations.
Absent of a UV-erasable window, this OTP EPROM cannot be erased or reprogrammed once programmed, providing tamper-proof memory storage ideal for critical data retention in industrial and embedded system environments. It mounts through-hole on PCBs for robust mechanical stability.
Operating temperature is rated from -40°C to 85°C, which suits extended industrial environmental conditions. The 32-pin PLCC package measures 11.5 mm in length, 14.3 mm in width, and 3.37 mm in height, balancing compact form with ease of installation.
The device’s supply current is low, at 100 microamps, significantly reducing power consumption in embedded applications. Typical use cases include industrial control, consumer electronics, and repair replacement memory where permanent data is essential.
The device’s OTP architecture allows permanent programming for secure memory storage. Parallel interface facilitates high-speed data communication. Compact 32-pin PLCC package provides durable mounting and easy integration.
Wide operating temperature range supports use in harsh industrial environments. Low supply current enhances energy-efficient designs. Through-hole mount type suitable for durable PCB assembly. Supports applications in embedded systems, industrial controls, and electronic devices.
