AM27C4096

The Am27C4096 is a 4 Mbit, ultraviolet erasable programmable read-only memory. It is organized as 256 Kwords, operates from a single +5 V supply, has a static standby mode, and features fast single address location programming. The Am27C4096 is ideal for use in 16-bit microprocessor systems. The device is available in windowed ceramic DIP packages, and plastic one time programmable (OTP) PDIP and PLCC packages.

Data can be typically accessed in less than 90 ns, allowinghigh-performance microprocessors to operate without any WAIT states. The device offers separate Output Enable (OE#) and Chip Enable (CE#) controls, thus eliminating bus contention in a multiple bus microprocessor system.

AMD's CMOS process technology provides high speed, low power, and high noise immunity. Typical power consumption is only 125 mW in active mode, and 125 W in standby mode.

All signals are TTL levels, including programming signals. Bit locations may be programmed singly, in blocks, or at random. The device supports AMD's Flashrite programming algorithm (100 s pulses), resulting in a typical programming time of 32 seconds.
