QP27C256 & QP27C256L QP27C256 – 256 Kilobit (32K x 8) CMOS EPROM June 18, 2009 General Description The QP27C256 is a 32Kx8 (256-Kbit), UV erasable programmable read-only memory. It operates from a single +5 V supply, has a static standby mode, and features fast single address location programming. The QP27C256 meets the same specification requirements and utilizes the same programming methodology as the AMD 27C256 that it replaces. Products are available in windowed and non-windowed (OTP) ceramic hermetic packages. Data is typically accessed in less than 55 ns, allowing high-performance microprocessors to operate without any WAIT states. The device offers separate Output Enable ( OE ) and Chip Enable ( CE ) pins, eliminating bus contention in a multiple bus system. Typical power consumption is only 80 mW in active mode, and 100 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...
