AT27C512R-90RC, 512-Kbit (64K x 8) One-Time Programmable OTP EPROM, PLCC-32

The AT27C512R-90RC is a 512-Kbit (64K x 8-bit) One-Time Programmable (OTP) EPROM designed for high-speed firmware storage in embedded systems, industrial applications, and microprocessor-based designs. With a fast 90ns access time, it enables efficient data access without compromising system performance.

Operating with a single 5V supply, this EPROM eliminates the need for additional programming voltages, simplifying circuit integration. The rapid programming algorithm ensures fast and reliable programming with 100µs per byte, making it ideal for high-volume production environments.

To ensure data integrity and long-term stability, the AT27C512R is built using CMOS technology, featuring 2,000V electrostatic discharge (ESD) protection and 200mA latch-up immunity. This ensures high reliability in harsh operating environments.

Encased in a PLCC-32 package, the AT27C512R-90RC is JEDEC standard compliant, making it compatible with a wide range of microcontrollers and embedded platforms. The two-line control (CE and OE) further enhances system flexibility by preventing bus contention.

Ideal for BIOS storage, industrial automation, telecommunications, and control systems, this OTP EPROM provides a secure and cost-effective solution for permanent firmware storage.
