MX27C2000

MX27C2000 2M-BIT [256K x 8] CMOS EPROM FEATURES 256Kx 8 organization Single +5V power supply +12.5V programming voltage Fast access time:35/45/55/70/90/100/120/150 ns Totally static operation Completely TTL compatible Operating current:30mA Standby current: 100uA Package type: 32 pin plastic DIP 32 pin SOP 32 pin PLCC 32 pin TSOP(I) GENERAL DESCRIPTION The MX27C2000 is a 5V only, 2M-bit, One Time Programmable Read Only Memory. It is organized as 256K words by 8 bits per word, operates from a single + 5 volt supply, has a static standby mode, and features fast single address location programming. All programming signals are TTL levels, requiring a single pulse. For programming outside from the system, existing EPROM programmers may be used. The MX27C2000 supports a intelligent fast programming algorithm which can result in programming time of less than one minute. This EPROM is packaged in industry standard 32 pin dual-in-line packages, 32 lead SOP, 32 lead PLCC and 32 lead TSOP (I) packages.
