It is organized as 512K bytes, operates from a single +5 V supply, has a static standby mode, and features fast single address location programming. The device is available in windowed ceramic DIP packages and plastic one-time programmable (OTP) packages. Data can be typically accessed in less than 90 ns, allowing high-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 100 mW in active mode, and 50 µW 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 µs pulses) resulting in typical programming time of 1 minute.
