The Atmel AT27C1024 is a low-power, high-performance 1,048,576-bit, one-time programmable, read-only memory (OTP EPROM) organized as 64K by 16 bits. It requires only one 5V power supply in normal read mode operation. Any word can be accessed in less

than 45ns, eliminating the need for speed reducing WAIT states. The x16 organization makes this part ideal for high-performance, 16- and 32-bit microprocessor systems.



In read mode, the AT27C1024 typically consumes 15mA. Standby mode supply current is

typically less than 10µA.



The AT27C1024 is available in industry-standard, JEDEC-approved, one-time programmable (OTP) PDIP and PLCC packages. The device features two-line control (CE, OE) to eliminate bus contention in high-speed systems
