AT27C2048-12PC [Microchip]

The AT27C2048 is a low-power, high performance 2,097,152-bit one-time programmable read only memory (OTP EPROM) organized 128K 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. Features include: Fast Read Access Time - 55 ns, Low Power CMOS Operation (100 µA Maximum Standby, 35 mA Maximum Active at 5 MHz), JEDEC Standard Packages (40-Lead 600 mil PDIP, 44-Lead PLCC, 40-Lead VSOP), Direct Upgrade from 512K-bit and 1M-bit 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.
