AT27C512R OTP EPROM, 64 K × 8 (512 Kbit), DIP/PLCC Package, 45 ns, 5 V One-Time Programmable Memory

The AT27C512R is a high-performance, low-power 524,288-bit One-Time Programmable (OTP) EPROM organized as 64 K × 8 bits. Manufactured using advanced CMOS technology, it offers fast read access times (as low as 45 ns) and low power consumption. This makes it ideal for embedded systems, firmware storage, and applications where reprogramming is not required. Designed for high-speed applications, the AT27C512R is available in standard DIP-28 and PLCC-32 packages, with compatibility across a wide range of EPROM programmers. It features high noise immunity, input/output TTL compatibility, and data retention exceeding 10 years. This EPROM is perfect for systems requiring permanent code storage, bootloaders, or fixed-function firmware—where cost-effective, tamper-proof memory is needed.

Key Features:

• 512 Kbit memory organized as 64 K × 8 (byte-wide)
• Fast read access time: as low as 45 ns
• CMOS technology for low power consumption
• Available in DIP-28 and PLCC-32 package formats
