CY7C276

The CY7C276 is a high-performance 16K-word by 16-bit CMOS PROM. The  CY7C276 is available in a 44-pin PLCC/CLCC and a 44-pin LCC packages, and is 100% reprogrammable in windowed packages. The memory cells utilize proven EPROM floating gate technology and word-wide programming algorithms.

The CY7C276 allows the user to independently program the polarity of each chip select (CS₂-CS₀). This provides on-chip decoding of up to eight banks of PROM. The polarity of the asynchronous output enable pin (OE) is also programmable.

In order to read the CY7C276, all three chip selects must be active and OE must be asserted. The contents of the memory location addressed by the address lines (A₁₃-A₀) will become available on the output lines (D₁₅-D₀). The data will remain on the outputs until the address changes or the outputs are disabled.
