CY7C261-20WC

The CY7C261-20WC is high-performance 8192-word by 8-bit CMOS PROMs. The CY7C261-20WC automatically power s down into a low-power standby mode,while deselected. It is packaged in a 300-mil-wide package.The reprogramm able package is equipped with an erasure window; when exposed to UV light, the PROM is erased and is able to th en be reprogrammed.The memory cells use proven EPROM floating-gate technology and byte-wide intelligent progra mming algorithms.

Features of the CY7C261-20WC are:(1) CMOS for optimum speed/power;(2)windowed for reprogrammability;(3)high speed:20 ns (commercial),25 ns (Military);(4)low power:660 mW (Commercial),770 mW (Military);(5)super low stand by power:Less than 220 mW when deselected,fast access is 20 ns;(6)EPROM technology 100% programmable;(7)sli m 300-mil or standard 600-mil packaging available;(8) 5V±10% VCC, commercial and military;(9)capable of withstan ding greater than 2001V static discharge.

The absolute maximum ratings of the CY7C261-20WC can be summarized as:(1):storage temperatures ranges from 65°C to+150°C;(2):ambient temperature with Power applied is55°C to+125°C;(3):supply voltage to ground potential(Pin 24 to Pin 12) is0.5V to+7.0V;(4):DC voltage applied to outputs in high Z state is0.5V to+7.0V; (5):D C input voltage is3.0V to + 7.0V;(6):DC program voltage(Pin 19 DIP, Pin 23 LCC) is 13.0V;(7):static discharge volt age is greater than 2001V;(8):latch-Up current is greater than 200 mA;(9):UV exposure is 7258 Wsec/cm2.
