CY7C263

1 CY7C261 CY7C263/CY7C264 8K x 8 Power-Switched and Reprogrammable PROM Features CMOS for optimum speed/power Windowed for reprogrammability High speed — 20 ns (Commercial) — 25 ns (Military) Low power — 660 mW (Commercial) — 770 mW (Military) Super low standby power (7C261) — Less than 220 mW when deselected — Fast access: 20 ns EPROM technology 100% programmable Slim 300-mil or standard 600-mil packaging available 5V ± 10% VCC, commercial and military Capable of withstanding greater than 2001V static discharge TTL-compatible I/O Direct replacement for bipolar PROMs Functional Description The CY7C261, CY7C263, and CY7C264 are high-performance 8192-word by 8-bit CMOS PROMs. When deselected, the CY7C261 automatically powers down into a low-power standby mode. It is packaged in a 300-mil-wide package. The CY7C263 and CY7C264 are packaged in 300-mil-wide and 600-mil-wide packages respectively, and do not power down when deselected. The reprogrammable packages are equipped with an erasure window; when exposed to UV light, these PROMs are erased and can then be reprogrammed. The memory cells utilize proven EPROM floating-gate technology and byte-wide intelligent programming algorithms. The CY7C261, CY7C263, and CY7C264 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 supervoltage and low current requirements allow for gang programmin...
