The Microchip AT27C512R-70JU-T: A High-Performance OTP EPROM Solution

In the realm of embedded systems and legacy hardware support, the need for reliable, non-volatile memory remains paramount. The Microchip AT27C512R-70JU-T stands as a robust and efficient solution, delivering 512 kilobits (64K x 8) of one-time programmable (OTP) memory. This EPROM (Erasable Programmable Read-Only Memory) chip is engineered for applications where data permanence is critical and firmware updates are either infrequent or unnecessary.

A key feature of this memory IC is its impressive 70ns maximum access time, which ensures swift data retrieval and is crucial for maintaining performance in systems synchronized with high-speed microprocessors. This speed makes it suitable for a range of demanding applications, from industrial automation and telecommunications infrastructure to automotive control systems and sophisticated consumer electronics.

Housed in a 32-lead PLCC (Plastic Leaded Chip Carrier) package, the AT27C512R-70JU-T offers a compact form factor and reliable connectivity, which is beneficial for space-constrained PCB designs. The OTP nature of this EPROM provides a significant advantage: once programmed, the data is permanently stored and immune to accidental erasure from UV light or electrical noise, guaranteeing integrity over the entire lifespan of the product. Its operation from a single 5V power supply simplifies system design and ensures compatibility with a wide array of digital logic families.

ICGOODFIND: The Microchip AT27C512R-70JU-T is a high-speed, high-reliability OTP EPROM memory chip. Its 70ns access speed, 512K density, and permanent data storage make it an excellent choice for final-code storage in demanding embedded systems that require long-term data stability.
