The Atmel AT27C256R-70PU is a high-performance, low-power, 262,144-bit one-time programmable (OTP) EPROM. Organized as 32K by 8 bits, it operates from a single 5V power supply and features a fast read access time of 45ns, eliminating the need for WAIT states in high-performance microprocessor systems.
This device utilizes Atmel's scaled CMOS technology, providing low active power consumption (typically 8mA) and minimal standby power (less than 10µA). It includes features such as 2,000V ESD protection and 200mA latchup immunity for high reliability. The rapid programming algorithm allows for efficient programming, typically at 100µs per byte.
The AT27C256R-70PU is available in industry-standard JEDEC packages, including 28-lead PDIP and 32-lead PLCC. It supports industrial and automotive temperature ranges and offers a green (Pb/halide-free) packaging option. Two-line control (CE, OE) provides flexibility to prevent bus contention.
