The AT27C256R-45TC is a low-power, high-performance 256Kbit one-time programmable (OTP) EPROM, organized as 32K x 8 bits. It features a fast read access time of 45 ns and operates on a single 5V power supply. The device consumes a maximum of 20 mA during active operation at 5 MHz and only 100 ¬µA in standby mode, making it suitable for low-power applications. This memory chip is available in various industry-standard packages, including 28-Lead PDIP, 32-Lead PLCC, and 28-Lead TSOP. It incorporates a Rapid,Ñ¢ Programming Algorithm that allows for programming times of approximately 100 ¬µs per byte. The AT27C256R also offers high reliability with 2,000V ESD protection and 200 mA latchup immunity. The device supports both CMOS and TTL compatible inputs and outputs, and includes an integrated product identification code for easy recognition by programming equipment. It is designed to operate across commercial, industrial, and automotive temperature ranges, making it versatile for different applications.
