27C4096

AT27C4096 Features Fast Read Access Time - 55 ns Low Power CMOS Operation – 100 µA Maximum Standby – 40 mA Maximum 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 bit, 1M bit, and 2M bit (AT27C516, AT27C1024, and AT27C2048) EPROMs 5V ± 10% Power Supply High Reliability CMOS Technology – 2,000V ESD Protection – 200 mA Latchup Immunity Rapid™ Programming Algorithm - 50 µs/word (typical) CMOS and TTL Compatible Inputs and Outputs Integrated Product Identification Code Commercial and Industrial Temperature Ranges 4-Megabit (256K x 16) OTP EPROM AT27C4096 Description The AT27C4096 is a low-power, high-performance 4,194,304-bit one-time programmable read only memory (OTP EPROM) organized 256K by 16 bits. It requires a single 5V power supply in normal read mode operation. Any word can be accessed in less than 55 ns, eliminating the need for speed-reducing WAIT states. The by-16 organization makes this part ideal for high-performance 16- and 32-bit microprocessor systems.
