Product Details
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. 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 |
