AT27C1024 Features Fast Read Access Time - 45 ns Low Power CMOS Operation – 100 µA max. Standby – 30 mA max. Active at 5 MHz JEDEC Standard Packages – 40-Lead 600-mil PDIP – 44-Lead PLCC – 40-Lead TSOP (10 mm x 14 mm) Direct Upgrade from 512K (AT27C516) EPROM 5V ± 10% Power Supply High Reliability CMOS Technology – 2000V ESD Protection – 200 mA Latchup Immunity Rapid™ Programming Algorithm - 100 µs/word (typical) CMOS and TTL Compatible Inputs and Outputs Integrated Product Identification Code Commercial and Industrial Temperature Ranges AT27C1024 1-Megabit (64K x 16) OTP EPROM AT27C1024 Description The AT27C1024 is a low-power, high-performance 1,048,576 bit one-time programmable read only memory (OTP EPROM) organized 64K by 16 bits. It requires only one 5V power supply in normal read mode operation. Any word can be accessed in less than 45 ns, eliminating the need for speed reducing WAIT states. The by-16 organization make this part ideal for high-performance 16- and 32-bit microprocessor systems.
