CY7C293A

92A CY7C291A CY7C292A/CY7C293A 2K x 8 Reprogrammable PROM Features Windowed for reprogrammability CMOS for optimum speed/power High speed — 20 ns (commercial) — 25 ns (military) Low power — 660 mW (commercial and military) Low standby power — 220 mW (commercial and military) EPROM technology 100% programmable Slim 300-mil or standard 600-mil packaging available 5V ±10% VCC, commercial and military TTL-compatible I/O Direct replacement for bipolar PROMs Capable of withstanding >2001V static discharge Functional Description The CY7C291A, CY7C292A, and CY7C293A are high-performance 2K-word by 8-bit CMOS PROMs. They are functionally identical, but are packaged in 300-mil (7C291A, 7C293A) and 600-mil wide plastic and hermetic DIP packages (7C292A). The CY7C293A has an automatic power down feature which reduces the power consumption by over 70% when deselected. The 300-mil ceramic package may be equipped with an erasure window; when exposed to UV light the PROM is erased and can then be reprogrammed. The memory cells utilize proven EPROM floating-gate technology and byte-wide intelligent programming algorithms. The CY7C291A, CY7C292A, and CY7C293A are plug-in replacements for bipolar devices and offer the advantages of lower power, reprogrammability, superior performance and programming yield. The EPROM cell requires only 12.5V for the supervoltage and low current requirements allow for gang programming. The EPROM cells allow for each memory location to be...
