MX27C4000MC-12
MX27C4000 4M-BIT [512K x8] CMOS EPROM FEATURES • • • • • • • Operating current: 40mA • Standby current: 100uA • Package type: 512K x 8 organization Single +5V power supply +12.5V programming voltage Fast access time: 90/100/120/150 ns Totally static operation Completely TTL compatible - 32 pin plastic DIP - 32 pin PLCC/SOP - 32 pin TSOP GENERAL DESCRIPTION programmers may be used. The MX27C4000 supports a intelligent fast programming algorithm which can result in programming time of less than two minutes. The MX27C4000 is a 5V only, 4M-bit, One Time Programmable Read Only Memory. It is organized as 512K 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 This EPROM is packaged in industry standard 32 pin dual-in-line packages, 32 lead PLCC, 32 lead SOP, and 32 lead TSOP packages.
