CY7C282A

The CY7C281A and CY7C282A are high-performance 1024-word by 8-bit CMOS PROMs.The CY7C281A and CY7C282A are functionally identical, but are packaged in 300-mil and 600-mil-wide packages respectively. The CY7C281A is also available in a 28-pin leadless chip carrier. The memory cells utilize proven EPROM floating-gate technology and byte-wide intelligent programming algorithms.

The CY7C281A and CY7C282A are plug-in replacements for bipolar devices and offer the advantages of lower power, superior performance, and programming yield. The EPROM cell requires only 12.5V for the super voltage, and low current requirements allow for gang programming. The EPROM cells allow each memory location to be tested 100% because each location is written into, erased, and repeatedly exercised prior to encapsulation. Each PROM is also tested for AC performance to guarantee that after customer programming, the product will meet DC and AC specification limits.

Reading of CY7C281A and CY7C282A  are accomplished by placing an active LOW signal on CS₁ and CS₂, and active HIGH signals on CS₃ and CS₄. The contents of the memory location addressed by the address lines (A₀ - A₉) will become available on the output lines (O₀ - O₇).
